This is a Stiletto Fly of the Therevidae family. Not an abundant group with about 140 North American species and only half these in the east. The adults are not that commonly seen and little is known of the adult habits. Often found on sunny trails and paths. Water and nectar drinkers, they are not predaceous. This particular fly was in the burned area of the Seven Hollows Trail of Petit Jean mountain. It enjoyed an open log landing place. Preferred landing sites apparently can separate genera and species sometimes. There were several in this area in spring. Open meadows and beaches are also common habitats for these interesting flies.

Less hairy and darker winged species which is also from Petit Jean. Will have to see what variation we have. It appears there are about ten genera of the group that occur in my area. Many of these flies are restricted to the west and southwest. Local genera for now are:

Litolinga (3 spp. catalog / 2 Nearctic list) [very prominent ocellar tubercle]

Brachylinga (10 spp. catalog / 6 Nearctic list) [abdomen gray or black, whitish scaly hairs on forefemur]

Dichoglena (4 spp. catalog / 4 Nearctic list) [female tergite 4 entirely shiny black]

Spiriverpa (9 spp. catalog / 8 Nearctic list) [frons with whitish pile and upper lateral face with whitish pile]

Penniverpa festina Coquillett 1893 (only spp. catalog / 1 Nearctic list) [foretibia and first tarsomere very slender]
