Machimus virginicus

This species is very similar to M. notatus. In Baker and Fischer’s 1975 paper on the Michigan Asilidae, they say that this species is more likely to be found in areas with lighter colored substrate such as a light sand. This would seem to mean that it might be more likely to be seen in the central sand areas of Wisconsin , but I have only collected two individuas of this species in Wisconsin and one in the sandy central Wisconsin counties.

Identifying characteristics

This species has the hind femur completely black, the tibia on the front legs that are less than 50% yellow or red markings, tarsi with red or yellow areas, and the epandria that is thin and not decurved at the tip.

Similar species

M. notatus is similar except that the epandria is stouter and decurved at the tip.

Habitat

Woodland edges and open areas in woodlands.

Flight

late June through August.

Abundance

Not nearly as common as M. notatus in Wisconsin.
