In 2020, we employed three techniques to collect EAB at a North Carolina (NC) site located at 35.64° N (purple prism traps [PPTs], log emergence, Cerceris fumipennis biosurveillance). The study was repeated in 2021, but with green funnel traps replacing log emergence. EAB collected by C. fumipennis in three altitudinally disparate regions of NC were also measured. Overall, EAB collected in 2020 averaged 12.02 mm, with those emerged from logs significantly smaller than those from PPTs. Length of females collected from C. fumipennis at three elevations was not significantly different and averaged 12.01 mm. In 2021, females collected from funnel traps, PPTs and C. fumipennis were not significantly different and larger ( x¯  = 12.41 mm) than in 2020; eliminating the smaller log‐emerged EAB from the 2020 data set did not change the outcome. Mean EAB size in NC never reached the reported 12.6 mm at 37° N, regardless of the technique or altitude tested. Our expansion of the latitudinal range in which EAB body size has been studied may shift the proposed converse Bergmann's cline to that of a sawtooth or other non‐linear model, likely associated with a transition in EAB voltinism at or near NC latitudes.}, journal={AGRICULTURAL AND FOREST ENTOMOLOGY}, author={Nalepa, Christine A. and Bohannon, G.

Because genetic monogamy is a suggested requirement for evolution of cooperative breeding/eusociality, particularly in hymenopterans, clarification of the mating biology of Cryptocercus would help illuminate evolutionary trends in eusocial insects. To investigate possible extra‐pair paternity in C. punctulatus, microsatellite markers were used to analyse offspring parentage, the stored sperm in females and results of experimental manipulation of sperm competition. Extra‐pair paternity was common in field‐collected families, but a lack of maternal alleles in several nymphs suggests sampling error or adoption. Isolating prereproductive pairs and assaying subsequently produced nymphs confirmed that nymphs lacked alleles from the pair male in 40% of families, with extra‐pair male(s) siring 27%–77% of nymphs. Sperm of extra‐pair males was detected in the spermatheca of 51% of paired prereproductive females. Mate switching and surgical manipulation of male mating ability indicated a tendency towards last male sperm precedence. Overall, the results demonstrate that about half of young females are serially monogamous during their maturational year, but bond, overwinter and produce their only set of offspring in company of the last mated male (=pair male). Repeated mating by the pair male increases the number of nymphs sired, but because many females use stored sperm of previous copulatory partners to fertilize eggs, pair males extend parental care to unrelated nymphs. The results suggest that genetic monogamy either developed in the termite ancestor after splitting from the Cryptocercus lineage, or that genetic monogamy may not be a strict prerequisite for the evolution of termite eusociality.}, journal={MOLECULAR ECOLOGY}, author={Yaguchi, Hajime and Kobayashi, Itaru and Maekawa, Kiyoto and Nalepa, Christine A.}, year={2021}, month={Oct} } @misc{nalepa_2020, title={Origin of Mutualism Between Termites and Flagellated Gut Protists: Transition From Horizontal to Vertical Transmission}, volume={8}, ISSN={["2296-701X"]}, DOI={10.3389/fevo.2020.00014}, abstractNote={Lower termites, as well as their sister group, the subsocial wood-feeding cockroach Cryptocercus, rely on flagellated eukaryotic symbionts in the hindgut to cooperatively digest their wood diet. In Cryptocercus these flagellates undergo encystment cycles tightly coordinated with the molting cycle of their host, yet the resultant cysts play no demonstrated role in their transmission to neonates; the trophozoite stage of the flagellates is passed directly from parents to offspring via hindgut fluids (proctodeal trophallaxis). This pattern suggests that encystment is a vestige from a gregarious cockroach ancestor, when the flagellates had a functional, two-stage life cycle and the cysts were horizontally transmitted among hosts via coprophagy. The strong integration between flagellate encystment cycles and host developmental physiology in Cryptocercus indicates that the relationship of the flagellates with their proposed gregarious cockroach ancestor was not commensal, but parasitic, with flagellates likely obtaining benefits by taking advantage of host gut metabolites and ingested plant debris. When vertical transmission evolved the parasites were ‘captured,’ and their fitness became inescapably embedded in the fitness of their host. The vertical transmission of gut flagellates and the origin of host subsociality via proctodeal trophallaxis can be considered two sides of the same coin. From the host point of view proctodeal trophallaxis marks the origination of parental care by provisioning neonates with nourishment, metabolites and beneficial microbiota. From the flagellate point of view, proctodeal trophallaxis was a shift from horizontal to vertical transmission, pushing them from the parasitic to the mutualistic end of the symbiotic spectrum, arguably making this host behavioral change the most critical juncture in the evolutionary trajectory of the termite lineage.}, journal={FRONTIERS IN ECOLOGY AND EVOLUTION}, author={Nalepa, Christine A.}, year={2020}, month={Feb} } @article{nalepa_shimada_maekawa_luykx_2017, title={Distribution of Karyotypes of the Cryptocercus punctulatus Species Complex (Blattodea: Cryptocercidae) in Great Smoky Mountains National Park}, volume={17}, ISSN={["1536-2442"]}, DOI={10.1093/jisesa/iex045}, abstractNote={During the period between 1999 and 2006, wood-feeding cockroaches in the Cryptocercus punctulatus Scudder species complex were collected throughout Great Smoky Mountains National Park, USA.

Based on molecular phylogenetic studies of multiple independent data (e.g., Lo et al., 2000; Inward et al., 2007), Cryptocercus and termites are shown to have a sister group relationship within the cockroach clade. The 2 groups also share multiple traits related to ecology, social structure, symbionts, and digestive physiology. Consequently, to discuss eusocial evolution in termites, Cryptocercus would serve as an important group for a “model-taxon by homology” (Klass et al., 2008). Adults of Cryptocercus spp. are completely wingless cockroaches. They typically pair up in late summer/early fall and initiate nest building, but they do not reproduce until the following summer (Nalepa, 1984). At that time, they produce several (up to 5) oothecae, each containing about 10−40 eggs; they then care for the hatched offspring (Nalepa, 1988, 1990). Coexisting with parents is necessary for the optimum development of offspring (Nalepa & Arellano, 2016). The logs these insects use for food and shelter vary greatly in size and are patchily distributed. Consequently, there is a possibility that new adults may either pair up and utilize decaying wood adjacent to their natal nest in a large log, leading to a relatively inbred mating strategy, or disperse to initiate nests in other logs on the forest floor, resulting in outbreeding.

This behavioural transition and the consequent transfer of costs associated with parental investment from adult parents to juvenile alloparents provides a baseline for the subsequent evolution of life history characteristics specific to extant OP termites, including a sterile soldier caste, small body size, extreme phenotypic plasticity, neotenic reproduction and interdependence of colony members. The hypothesis is also consistent with the reproductive and developmental physiology of cockroaches in a nitrogen-limited environment (Nalepa, 2011a,b, 2015). A contrary view, that alloparental brood care is not a necessary prerequisite for termite eusociality is advanced by Korb et al. (2012) and Korb (2007, 2015), who observed little to no brood care behaviour in alloparents originating from established colonies of drywood termites (Cryptotermes). It is further argued that one component of brood care, proctodeal trophallaxis, would be of little or no cost to individual caregivers because the behaviour is typically a reciprocal interaction (Korb, 2007, 2008a,b, 2010a). Here I suggest that there is little evidence to support claims of the absence of brood care and its correlate, independent offspring, in extant OP termites, and the notion that proctodeal feeding is not costly to individual alloparents is based on misconceptions regarding what may be considered ‘ancestral’ in a termite.}, number={1}, journal={ECOLOGICAL ENTOMOLOGY}, author={Nalepa, Christine A.}, year={2016}, month={Feb}, pages={27–30} } @article{tai_carpenter_weber_nalepa_perlman_keeling_2016, title={Genome Evolution and Nitrogen Fixation in Bacterial Ectosymbionts of a Protist Inhabiting Wood-Feeding Cockroaches}, volume={82}, ISSN={["1098-5336"]}, DOI={10.1128/aem.00611-16}, abstractNote={ABSTRACT}, number={15}, journal={APPLIED AND ENVIRONMENTAL MICROBIOLOGY}, author={Tai, Vera and Carpenter, Kevin J. and Weber, Peter K. and Nalepa, Christine A. and Perlman, Steve J. and Keeling, Patrick J.}, year={2016}, month={Aug}, pages={4682–4695} } @article{nalepa_arellano_2016, title={Parental social environment alters development of nutritionally independent nymphs in Cryptocercus punctulatus (Dictyoptera: Cryptocercidae)}, volume={70}, ISSN={["1432-0762"]}, DOI={10.1007/s00265-016-2110-6}, number={6}, journal={BEHAVIORAL ECOLOGY AND SOCIOBIOLOGY}, author={Nalepa, C.

Dealates had significantly fewer antennal segments than alates in 14 of the 16 termite species, with both exceptions belonging to the family Termitidae.

An examination of the literature indicates that the basis for these unique ontogenetic characters is not the prolongation of a pronymphal stage into postembryonic development, as recently suggested. Like other hemimetabolous insects, termites have three embryonic cuticles, and the pronymphal (EC3) cuticle is shed during or shortly after hatch. Nonetheless, a different developmental landmark, dorsal closure, occurs later during embryogenesis in termites than it does in their cockroach relatives, clearly indicating ontogenetic repatterning from an ancestral state. An alternate hypothesis for the origin of isopteran phenotypic plasticity becomes apparent if we remain focused on the phylogenetic and social context of termite evolution. Altricial development occurs in both vertebrate and invertebrate taxa, evolves in response to the parental environment, and is displayed by two distantly related, biparental, wood‐feeding cockroaches, includingCryptocercus, the sister‐group to termites. It is therefore likely the condition was present in subsocial termite ancestors, and played a complex, multidimensional role in the transition to eusociality. Most relevant to current arguments is that a shift in responsibility for the care of altricial dependents, from parents to the first nutritionally independent nymphs in the family (alloparents), resulted in the developmental stasis of alloparents at a relatively young age. Because early instar cockroaches are not metamorphically competent, these young alloparents would have provided a novel developmental template on which selection could act.}, number={1}, journal={EVOLUTION & DEVELOPMENT}, author={Nalepa, Christine A.}, year={2010}, pages={95–105} } @inproceedings{nalepa_2010, title={Elizabeth Anne McMahan: In Memorium (1924-2009)}, volume={56}, number={1}, booktitle={Sociobiology}, author={Nalepa, C.

In cockroaches, these glands produce secretions that cover two parallel rows of eggs during oviposition, and in oviparous species, these secretions become the tanned, sculpted, rigid outer casing of the ootheca. The goal of this study was to compare the gross anatomy of the colleterial glands and the ultrastructure of their component tubules in the phylogenetically significant genera Cryptocercus (Blattaria) and Mastotermes (Isoptera). Recent studies indicate that cockroaches in the genus Cryptocercus are the sister group of termites, and Mastotermes is the only termite known to produce a cockroach-like ootheca. One additional oviparous cockroach, Therea, and two additional termites, Zootermopsis and Pseudacanthotermes, were also examined. As in other cockroaches, the colleterial glands of Cryptocercus and Therea are asymmetrical, with a well developed bipartite left gland and a smaller right gland. In the termites Mastotermes, Zootermopsis, and Pseudacanthotermes, the colleterial glands are composed of a well-developed, paired, anterior gland and a small posterior gland; histological staining and cytological evidence suggest that these are homologues of the left and the right colleterial glands of cockroaches, respectively. At the ultrastructural level, colleterial gland tubules are made of cells belonging to a modified class 1 type cell in the cockroaches, in Mastotermes, and in Zootermopsis; the latter lays its eggs singly, without a surrounding ootheca-like structure. In the advanced termite Pseudacanthotermes, the tubules are made of secretory units belonging to the class 3 cell type. This study demonstrates that the cytological characteristics of colleterial glands in basal termites are similar to those of cockroaches, whether the termite secretes an oothecal casing that covers two parallel rows of eggs, as in Mastotermes, or lays its eggs singly, as in Zootermopsis.

Cryptocercus cockroaches have appeared to many as ideal models for inference on the early evolution of termites, due to their possible phylogenetic relationship and several shared key attributes in life history. Recently, Pellens, Grandcolas, and colleagues have proposed the blaberid cockroach Parasphaeria boleiriana to be an alternative model for the early evolution in termites. We compare the usefulness of Cryptocercus and P. boleiriana as models for termite evolution. Cryptocercus and lower Isoptera (1) can both feed on comparatively recalcitrant wood, (2) have an obligate, rich and unique hypermastigid and oxymonadid fauna in the hindgut, (3) transfer these flagellates to the next generation by anal trophallaxis, (4) have social systems that involve long-lasting biparental care, and, finally, (5) are strongly suggested to be sister groups, so that the key attributes (1)–(4) appear to be homologous between the two taxa. On the other hand, P. boleiriana (1) feeds on soft, ephemeral wood sources, (2) shows no trace of the oxymonadid and hypermastigid hindgut fauna unique to Cryptocercus and lower Isoptera, nor does it have any other demonstrated obligate relationship with hindgut flagellates, (3) is likely to lack anal trophallaxis, (4) has only a short period of uniparental brood care, and (5) is phylogenetically remote from the Cryptocercus + Isoptera clade. These facts would argue against any reasonable usage of P. boleiriana as a model for the early evolution of Isoptera or even of the clade Cryptocercus + Isoptera. Cryptocercus thus remains an appropriate model-taxon-by-homology for early termite evolution. As compared to P. boleiriana, some other Blaberidae (such as the Panesthiinae Salganea) appear more useful as model-taxa-by-homoplasy for the early evolution of the Cryptocercus + Isoptera clade, as their brooding behavior is more elaborate than in P. boleiriana.}, number={3}, journal={MOLECULAR PHYLOGENETICS AND EVOLUTION}, author={Klass, Klaus-Dieter and Nalepa, Christine and Lo, Nathan}, year={2008}, month={Mar}, pages={809–817} } @book{bell_roth_nalepa_2007, title={Cockroaches: Ecology, behavior, and natural history}, ISBN={0801886163}, publisher={Baltimore: Johns Hopkins University Press}, author={Bell, W.

One of the primary recommendations for managing this annual influx is to prevent beetle entry by caulking or otherwise filling potential entry points in buildings. The goal of this study was to determine how small a gap the beetles are able to enter in choice and no-choice studies by experimentally exploiting their behavioral tendency to seek dark shelters at cool temperatures. Within the size range of adults collected in central North Carolina in 2003 (1.99–3.29 mm body height), no beetles entered a 2-mm access during no-choice experiments. Most (83%) entered a 3-mm gap; those failing to cross the 3-mm threshold were significantly larger than those that traversed it. In choice experiments, 98.2% of beetles entered shelters. As in the previous study, no beetles entered shelters with 2-mm gaps. Significantly fewer were found in shelters with 3-mm entrances than in those with 4- or 5-mm access; beetles that entered 3-mm gaps were significantly smaller than the remainder of the test population. Although no H. axyridis crossed a 2-mm threshold in either experiment, a gap of this size may nonetheless allow admission if it has flexible borders (e.g., foam weather stripping); beetles were observed attempting forced entry into too-small crevices.}, number={5}, journal={JOURNAL OF ECONOMIC ENTOMOLOGY}, author={Nalepa, Christine A.}, year={2007}, month={Oct}, pages={1633–1636} } @article{nalepa_weir_2007, title={Infection of Harmonia axyridis (Coleoptera : Coccinellidae) by Hesperomyces virescens (Ascomycetes : Laboulbeniales): Role of mating status and aggregation behavior}, volume={94}, ISSN={["0022-2011"]}, DOI={10.1016/j.jip.2006.11.002}, abstractNote={The ectoparasitic fungus Hesperomyces virescens was studied on Harmonia axyridis in North Carolina, in the southeastern United States. A primary goal was to investigate transmission of the disease by examining the correlation between the pattern of fungal infection and seasonal change in host behavior. Beetles were collected as they arrived at their winter quarters at two sites; in one site they were also subsampled at mid- and late winter. Insects were sexed and weighed, fungal thalli were counted, and their location on the host body mapped; spermathecae of females were examined for sperm. Infection levels varied between sites, differed significantly between the sexes in one site but not the other, and increased by approximately 40% during winter. The distribution of thalli on the body changed seasonally, in concert with behavioral changes in the host. At fall flight, thalli were found most often on the posterior elytra of mated females, virgin females, and males. This is suggestive that the disease had been spread among both sexes via successful and failed copulation attempts; however, the relatively low incidence of infection on the male venter does not fit the sexual transmission scenario. During winter, thallus location shifts in concert with beetle aggregation behavior, with infections more often located on the head and legs. Fresh weight of beetles decreased by approx. 20% during winter, but was not affected by disease status. Prior to spring flight, uninfected females were preferred as mating partners, but the probable relationship between female age and infection status complicates interpretation of the data.}, number={3}, journal={JOURNAL OF INVERTEBRATE PATHOLOGY}, author={Nalepa, Christine A. and Weir, Alexander}, year={2007}, month={Mar}, pages={196–203} } @article{lo_engel_cameron_nalepa_tokuda_grimaldi_kitade_krishna_klass_maekawa_et al._2007, title={Save Isoptera: A comment on Inward et al.}, volume={3}, ISSN={["1744-9561"]}, DOI={10.1098/rsbl.2007.0264}, abstractNote={A number of phylogenetic studies during the last decade have shown that termites—one of the main groups of eusocial insects—are a type of cockroach, whose closest living relative is the wood-feeding genus Cryptocercus (reviewed in [Klass & Meier (2006)][1] and [Inward et al.

Open field experiments were conducted during the autumn flight to examine the role of linear contrast in visually attracting beetles. White targets printed with 61 by 15-cm stripes that varied in orientation and degree of contrast were covered in insect adhesive, attached to a white background panel, and erected in sites known to be attractive to flying beetles. Flights occurred when temperatures rose above 21°C. Diurnally, peak flight occurred between 1400 and 1600 hours but shifted progressively earlier within that framework as the flight season advanced. Beetles significantly chose targets with high contrast, black stripes; the number of beetles landing on all other contrast levels did not differ significantly from controls. Vertically positioned stripes attracted more beetles than horizontal ones, but not significantly. The effects of high contrast were absolute rather than relative. The number of beetles landing on targets with 50% contrast stripes did not increase when these were the highest contrast targets available. Results suggest that visual intensity contrast is key to understanding the behavior of H. axyridis in autumn and call into question some commonly accepted ideas regarding choice of overwintering sites. First, during migratory flight, H. axyridis is not visually attracted to the color white per se, and second, it is unlikely that, during flight, pheromones are involved in beetle orientation.}, number={2}, journal={ENVIRONMENTAL ENTOMOLOGY}, author={Nalepa, CA and Kennedy, GG and Brownie, C}, year={2005}, month={Apr}, pages={425–431} } @article{nalepa_kennedy_brownie_2004, title={Orientation of multicolored Asian lady beetles to buildings}, volume={50}, number={3}, journal={American Entomologist (Lanham, Md.)}, author={Nalepa, C.

A re-examination of the evidence, however, fails to support their hypothesis. First, their analysis of host preferences was based on a general description of forest type, rather than on the level at which host choice occurs: the dead tree on the forest floor. Cryptocercus in both East Asia and in the eastern United States have been collected from a range of evergreen and deciduous logs. Although C. clevelandi in the western United States is associated primarily with conifers, no evidence of host adaptation exists. Second, there is no support for the described evolutionary trend toward low-altitude habitats among karyotype groups of C. punctulatus in the eastern United States. The findings of Kambhampati et al. are based on inadequate sampling; they did not include the highest and most topographically complex regions of the Southern Appalachian Mountains, nor the lower elevation border regions to the north and east of the range. An analysis of elevational data from 71 collection sites revealed no significant difference in the range of altitudes at which karyotype groups of C. punctulatus are found. In contrast to the suggestions of these authors, a lack of specialization with regard to altitude and host logs was probably the factor that allowed all taxa in the genus to thrive during climatically driven shifts in the geographical location and plant species composition of northern hemisphere mesic forests. © 2003 The Linnean Society of London, Biological Journal of the Linnean Society, 2003, 80, 223–233.}, number={2}, journal={BIOLOGICAL JOURNAL OF THE LINNEAN SOCIETY}, author={Nalepa, CA}, year={2003}, month={Oct}, pages={223–233} } @article{deitz_nalepa_klass_2003, title={Phylogeny of the Dictyoptera Re-examined (Insecta)}, volume={61}, number={1}, journal={Entomologische Abhandlungen}, author={Deitz, L..

Populations with different karyotypes are geographically structured in a mosaic, with at least one karyotype occurring in two disjunct regions. Abrupt geographic transitions between karyotypes suggest a parapatric distribution. We found no overlap in the distribution of the different karyotypes, as recently suggested. Although the boundary zones between karyotypes do not appear to coincide with physical or ecological barriers to dispersal, several transitions between karyotypes occur on or near the highest mountains in the southern Appalachians. We suggest that the different karyotypes arose by vicariance, with current boundaries formed by secondary contact when populations isolated in glacial refugia subsequently spread into high-mountain habitats. Because of their dependence on mature mesic forests, populations of the cockroach likely advance up and down mountainsides in cycles of advances and retreats dictated by climatic oscillations that raise and lower the timberline. We discuss the taxonomic status of the different karyotype groups in the C. punctulatus complex, and conclude that more exacting evidence is required to establish if species-level status is warranted.

DNA sequence analysis of the bacteria in the two taxa shows them to be phylogenetically related; thus, it has been suggested that the bacteriocyte symbiosis was established in an ancestor common to cockroaches and termites, with a loss of the symbiosis in all other known termite lineages. The offspring of both cockroaches and Mastotermes acquire the symbiosis via transovarial transmission. However, transmission of the bacteria in Mastotermes has not been examined since the pioneering works carried out by Koch in the 1930s. Here we report on transovariole transmission in primary and neotenic reproductives, and show that the ovarioles of both harbor fat body, which contains bacteriocytes. The conspicuous number of ovarian bacteriocytes in neotenic queens corresponds to the pattern previously observed in female nymphs. Bacterial transmission to offspring during the life of the colony thus occurs through continuous provisioning of symbionts to the ovariole from bacteriocytes in ovarian fat body. This pattern parallels that of cockroaches as does the entire mechanism of transovarial transmission.}, number={6}, journal={ANNALS OF THE ENTOMOLOGICAL SOCIETY OF AMERICA}, author={Sacchi, L and Nalepa, CA and Lenz, M and Bandi, C and Corona, S and Grigolo, A and Bigliardi, E}, year={2000}, month={Nov}, pages={1308–1313} } @article{frohlich_sass_babenzien_kuhnigk_varma_saxena_nalepa_pfeiffer_konig_1999, title={Isolation of Desulfovibrio intestinalis sp nov from the hindgut of the lower termite Mastotermes darwiniensis}, volume={45}, ISSN={["0008-4166"]}, DOI={10.1139/cjm-45-2-145}, number={2}, journal={CANADIAN JOURNAL OF MICROBIOLOGY}, author={Frohlich, J and Sass, H and Babenzien, HD and Kuhnigk, T and Varma, A and Saxena, S and Nalepa, C and Pfeiffer, P and Konig, H}, year={1999}, month={Feb}, pages={145–152} } @article{nalepa_bandi_1999, title={Phylogenetic status, distribution, and biogeography of Cryptocercus (Dictyoptera : Cryptocercidae)}, volume={92}, ISSN={["1938-2901"]}, DOI={10.1093/aesa/92.3.292}, abstractNote={Recent morphological studies on Blattaria, as well as molecular data on both these insects and their fat body bacterial endosymbionts, do not agree with Grandcolas's phylogenetic placement of Cryptocercus deep within the Polyphaginae [Grandcolas, P. 1999.

Postparturition parental care is likewise diverse, ranging from species in which females remain with neonates for a few hours, to biparental care that lasts several years and includes feeding the offspring on bodily fluids in a nest. Both ovoviviparity and parental care arose a number of times in the taxon. Evolution of reproductive mode seems most influenced by predators, parasites and cannibalism. Ovoviviparity, aggregation behavior of young nymphs, and diet are suggested as factors influential in the evolution of postparturition parental care. Females regulate parental investment via absorption of oocytes, abortion, cannibalism and brood reduction. The developmental status of cockroaches at hatching ranges along an altricial–precocial spectrum and is correlated with the presence and type of parental care. In several subsocial species neonates are blind, poorly sclerotized, and dependent for food, while in the sole viviparous cockroach nymphs hatch in an advanced state of development and require fewer molts to adulthood than any known cockroach. Association with microorganisms in both the digestive system and the fat body is suggested as one factor influential in the repro – ductive versatility of cockroaches. In particular, the endosymbiont flavobacteria which mediate the storage and recycling of nitrogenous waste products may allow for the variety of modes of postovulation provisioning of offspring.}, booktitle={Social competition and cooperation in insects and Arachnids}, publisher={Cambridge: Cambridge University Press}, author={Nalepa, C.

Females of the subsocial woodroach Cryptocercus punctulatus Scudder generally have a single oviposition period during which they produce one to four oöthecae. Monogamous pairs and their recently deposited oöthecae were collected in the field, and measured, weighed and analysed for nitrogen in the laboratory. Females put 9.8 ± 2.4% (mean ± SD) of their dry weight and 11.6 ±0.5% of their body nitrogen into oöthecae. The total nitrogen and dry weight of the brood were positively related to the post‐oviposition total nitrogen and dry weight of the mother. A female's investment, on a per nymph basis, averaged 0.06% of her post‐oviposition dry weight. Females may be able to recover up to 58.7% of the nitrogen invested into a brood by consuming the egg cases after hatch. Overall, there was little variation in the width of head capsules of adults in this species, and this parameter was not significantly different between the sexes. Females were heavier than males (dry weight) (P =0.06). Within pairs, the weights and nitrogen contents of males and females were positively correlated, probably because they feed together in the same log for nearly a year prior to reproduction.}, number={3}, journal={Physiological Entomology}, author={Nalepa, C.
