Order DIPTERA

Family BOMBYLIIDAE

(Bee Flies)

(Table of Species)

The Bee Flies (797 NA spp) generally have hairy bodies and patterned wings and several with long beaks feed at flowers. They are a conspicuous element of CCESR old fields and are routinely collected in small numbers from primarily xeric fields in mid-summer. Perhaps 20 species have been collected. The larvae of this family are predators on grasshopper egg pods or the larvae of ground-nesting bees and wasps. Adult females can be seen hovering over and flicking eggs into promising depressions in the soil. The most commonly collected species are in the genera: Villa (lateralis, alternata, fulviana), Hemipenthes sinuosa, Exoprosopa fascipennis., Anthrax spp(analis, irroratus, DK wing), Paravilla, Chrysanthrax cypris, and Poecilanthrax spp(alcyon, tegminipennis). Others often found at flowers include: Anastoechus barbatus, Systoechus vulgaris, Bombylius spp (major). The humpbacked Lepidophora? sp seems to prefer Pycnanthemumvirginianum and small yellow species of Phthiria are common on goldenrod. Aphoebantus sp, Geron sp, and Glabellula sp have also been collected. Glabellula being taken at Amelanchier blooms in May.
