| Title: | Trigonalyidae (Hymenoptera) in the eastern United States: Seasonal flight activity, distributions, hosts |
| Abstract: | Three of the four Nearctic species of Trigonalyidae occur in the eastern United States, Orthogonalys pulchella (Cresson), Taeniogonalos gundlachii (Cresson) (= Poecilogonalos costalis (Cresson)), and Lycogaster pullata Shuckard. Seasonal flight data is determined from collections of 4272 specimens from eight study sites in Maryland, Virginia, and West Virginia. Orthogonalys pulchella and T. gundlachii flights begin in mid-May and peak in June and the first of July, but both species are present in low numbers through the first of October. The flight period of L. pullata could not be determined. Identification, distributions, hosts, and habitats are reviewed for each species. |
