Dispersal is often the suggested mechanism of diversification in the South Pacific, specifically among remote island chains. Here, we provide a phylogeny of several related genera of Coenagrionidae (Odonata: Zygoptera) from the South Pacific, based on five molecular loci, in order to examine patterns of speciation in the region. We used the endemic damselfly genera Nesobasis, Nikoulabasis, and Vanuatubasis found across both Fiji and Vanuatu. Knowledge of the geologic history of the region was used to inform our understanding of the evolution of these genera. Both archipelagos used to be part of the Vitiaz arc which spanned from the Solomon Islands to Tonga and began to break apart 10–12 Ma. Results of our divergence-time estimations and biogeographic reconstructions support that the breakup of this arc acted as a significant vicariance event in the evolution of these taxa. Specifically, it led to the extant generic diversity seen in these damselflies. We find that within the archipelago of Vanuatu, that Espiritu Santo served as an important source for dispersal to other islands with Malekula acting as a stepping stone to Efate.}, journal={Molecular Phylogenetics and Evolution}, publisher={Elsevier BV}, author={Saxton, Natalie A. and Powell, Gareth S. and Bybee, Seth M.}, year={2023}, month={Sep}, pages={107831} }

Understanding the timing of its origins, however, can help elucidate the evolution of this ecologically important signal. Using fireflies, a prevalent bioluminescent group where bioluminescence primarily functions as aposematic and sexual signals, we explore the origins of this signal in the context of their potential predators. Divergence time estimations were performed using genomic-scale datasets providing a robust estimate for the origin of firefly bioluminescence as both a terrestrial and as an aerial signal. Our results recover the origin of terrestrial beetle bioluminescence at 141.17 (122.63–161.17) Ma and firefly aerial bioluminescence at 133.18 (117.86–152.47) Ma using a large dataset focused on Lampyridae; and terrestrial bioluminescence at 148.03 (130.12–166.80) Ma, with the age of aerial bioluminescence at 104.97 (99.00–120.90) Ma using a complementary Elateroidea dataset. These ages pre-date the origins of all known extant aerial predators (i.e. bats and birds) and support much older terrestrial predators (assassin bugs, frogs, ground beetles, lizards, snakes, hunting spiders and harvestmen) as the drivers of terrestrial bioluminescence in beetles. These ages also support the hypothesis that sexual signalling was probably the original function of this signal in aerial fireflies.}, number={1979}, journal={Proceedings of the Royal Society B: Biological Sciences}, author={Powell, Gareth S. and Saxton, Natalie A. and Pacheco, Yelena M. and Stanger-Hall, Kathrin F. and Martin, Gavin J. and Kusy, Dominik and Felipe Lima Da Silveira, Luiz and Bocak, Ladislav and Branham, Marc A. and Bybee, Seth M.}, year={2022}, month={Jul} }

In the case of visual cues, color signals are thought to have been shaped in large part by the spectral sensitivity of key pollinators, such as hymenopterans. Beetles were some of the first plant pollinators, pre-dating the angiosperm radiation but with the exception of a few well-studied species, the evolution of flower-visiting beetle visual systems is poorly understood. Thus, the ability of beetles to detect and distinguish flower color signals and perhaps their potential role in shaping flower coloration is not well understood. Traditional models of pollinator visual systems often assume a putative tri- or tetrachromatic flower-visitor, as is found in bees, flies and butterflies. Beetles are unique among modern pollinators as ancestrally they did not possess the machinery for trichromatic vision, lacking the blue-sensitive photoreceptor class. Research on the evolution of visual genes responsible for wavelength sensitivity (opsins) has revealed that beetles with putative tri- and tetrachromatic visual systems have evolved independently, along multiple lineages. We explore the evolution of beetle visual genes using newly generated and publicly available RNA-seq data from 25 species with flower associations, including previously unexplored key flower-visitor groups and 20 non-flower visiting relatives. Our findings serve as a resource to inform and guide future studies on beetle-flower interactions, where insight from both signal and receiver is needed to better understand these poorly explored systems.}, journal={Frontiers in Ecology and Evolution}, publisher={Frontiers Media SA}, author={Sharkey, Camilla R. and Powell, Gareth S. and Bybee, Seth M.}, year={2021}, month={Jun} }

According to Kirejtshuk (2008), there are seven genera and 13 subgenera within Carpophilinae. To date, however, no comprehensive tribal or generic phylogenetic reconstructions have been published for the subfamily. This work constitutes a preliminary stage of a larger project that will address the subfamily in a rigorous taxonomic and systematic framework. A stable taxonomic foundation for Carpophilus species and other Carpophilinae taxa is needed to ensure the validity of future work in the subfamily.

However, the regional variation in species composition remains unresolved and the seasonal phenology of several species has not been well documented. The latter gap is largely due to the inability to identify the larval stage to species-a confounding problem with several sympatric insect species. We used field trapping (adults) and soil sampling (larvae and pupae) surveys along with a DNA-based life-stage association to characterize the biology of billbugs associated with turfgrass in the Midwestern United States. Pitfall trapping at four locations in Indiana revealed four billbug species: S. venatus Say, S. parvulus Gyllenhaal, S. minimus Hart, and S. inaequalis Say. Sphenophorus venatus was the most abundant species on warm-season turfgrass while S. parvulus was most abundant on cool-season turfgrass. Investigation of S. venatus seasonal biology revealed two overwintered life stages-larva and adult-which resulted in two overlapping cohorts and two larval generations. Degree-day models describing S. venatus activity were more accurate for first-generation adults and larvae than for overwintering life stages. Maximum-likelihood analyses provided the first molecular species identification of billbug larvae and direct evidence that S. venatus larvae are capable of overwintering above 40°N latitude. Findings clarify the utility of molecular markers (CO1, 18S, and ITS2) for describing billbug larval population dynamics and seasonal phenology in regions where several sympatric billbug species occur. These results support the development of sustainable management strategies based on billbug seasonal phenology in different regions of North America.}, number={1}, journal={Journal of Economic Entomology}, publisher={Oxford University Press (OUP)}, author={Duffy, Alexandra G and Powell, Gareth S and Zaspel, Jennifer M and Richmond, Douglas S}, year={2018}, month={Jan}, pages={304–313} }

 The genus Calyptra Ochsenheimer is known for its atypical behavior of exhibiting both obligate fruit piercing and facultative blood feeding as adults. The genus has been reported piercing a vast array of fruits including citrus, figs, grapes, and raspberries. One species, Calyptra canadensis (Bethune), more commonly known as the Meadow Rue Owlet moth, is the only member of the genus known to occur in the New World. The extent of this species' range, along with its adult host breadth, remains unknown. Museum specimens of C. canadensis from 20 institutions and private collections were examined and georeferenced to generate the most comprehensive distribution map for the species to date. Locality data was analyzed to explore the phenology of C. canadensis, recovering an adult activity period from May to October. Larval rearing experiments were also undertaken, documenting the presence of five larval instar stages and a development time ranging from 6 to 8 weeks. Overall this study expands what is currently known about the biology of C. canadensis, specifically its larval development, adult distribution, and activity period.}, number={4}, journal={Journal of the Lepidopterists’ Society}, publisher={Lepidopterists' Society}, author={Snyder, Julia L. and Powell, Gareth S. and Behring, Robert S. and Alford, Adam M. and Mccarty, Megan E. and Zaspel, Jennifer M.}, year={2016}, month={Dec}, pages={253–259} }

While a few species of saproxylic beetles are considered to be pests, the majority of species perform important ecological roles such as decomposition, nutrient recycling, pollination in the mobile adult form, or act as food sources for other organisms. Their diversity and variable responses make them good biological indicators. Promoting biodiversity in managed areas, such as golf courses, may be relatively easy by creating saproxylic habitat. We examined the influence on saproxylic beetle communities of habitat type, log type, and distance from a fairway. Sentinel logs were provided for colonization for one season, and emergence was monitored over the following 2 years. We found that beetle species richness increased with log volume but did not change with distance from the fairway playing surface. Our findings suggest that although species richness may be low compared with that in less fragmented habitats, a diverse assortment of saproxylic beetles can be supported in golf course wooded habitats. This may be accomplished by leaving fallen trees in place when they do not pose a hazard or interfere with play. In particular, the provision of large woody debris that is more difficult to remove may maximize the benefit to superintendents and the saproxylic beetle community. Findings also support the idea that golf courses containing woody patches may increase habitat connectivity for these insects, and possibly other organisms, in otherwise highly fragmented urban areas.}, number={1}, journal={Crop, Forage & Turfgrass Management}, publisher={Wiley}, author={Powell, Gareth S. and Shukle, John T. and Richmond, Douglas S. and Holland, Jeffrey D.}, year={2016}, month={Apr}, pages={1–8} }

Recognition: This family may be recognized by the following combination of adult characters: maxilla lacking galea; antennae typically 11-segmented, with terminal three antennomeres forming a club; antennal insertions moderately to broadly separated; subocular antennal grooves on ventral surface of head present; procoxae transverse with exposed trochantins; prosternum transverse with intercoxal process extending between procoxal cavities, procoxae always separated; mesoventral procoxal rests present; typically five visible abdominal ventrites present; metendosternite stalk present; metasternum with discrimen present; and tarsal formula 5-5-5. Habitat: Several recent comprehensive reviews of Nitidulidae biology are available (Jelinek et al., 2010; Cline, 2005; Audisio et al., 2000; Audisio, 1993). Overall, nitidulid beetles exhibit a diverse set of life history strategies, including: fungivory, saprophagy, phytophagy, pollination activities, facultative predation, necrophagy, frugivory, and inquilinism with social insects. Nitidulids may be collected using a variety of directed (sweeping and beating vegetation/inflorescences, sifting leaf litter, searching under bark and various fungal substrates, as well as in nests of social Hymenoptera) and passive techniques (flight intercept traps, pitfall traps, malaise traps, and mercury vapor or black lights at night). Large numbers of nitidulids can typically be found in palm inflorescences (e.g., Mytrops and related genera); baited fruit or molasses traps (Carpophilus, Colopterus, Brachypeplus, Amphicrossus, Lobiopa, and Cryptarcha), and sifting leaf litter (Stelidota). Notes: Nitidulidae have long been confused with numerous other families of Cucujoidea. In particular, members of Cybocephalidae, Kateretidae, Monotomidae, Cryptophagidae, Biphyllidae, Smicripidae, and Erotylidae have been attributed to Nitidulidae. Recent and upcoming work on the New World Kateretidae (Cline and Audisio, 2010, and unpubl. data) will help improve the diagnostic capabilities for Nitidulidae. A recent treatment of Nitidulidae higher level phylogenetics formally elevated Cybocephalidae to family status and provided an extensive list of adult and larval characters to differentiate this group from Nitidulidae (Cline et al., 2014). Invasive species such as Urophorus humeralis (F.), Epuraea luteola Erichson, and Carpophilus hemipterus (L.) likely occur in the country as they have been transported around the world in various agricultural commodities, in conjunction with several other alien species more or less recently introduced into Peru (Carrasco, 1986; Leschen and Marris, 2005; EPPO, 2010).
