Thresholds for flight were 18°C, 5.38 milliphots (5 ft-c) of light, and wind speed below 60–70 m/min. No gnats were captured at a vapor pressure deficit of 0.0 mm Hg. Graphs are presented for flight activity at various values of temperature, light, VPD, and wind speed. Comparisons are made between the responses of H. pusio and H. pallipes to temperature, light, VPD, and wind speed.}, number={3}, journal={Journal of Medical Entomology}, author={Gerhardt, R.
