Large, bee/wasp mimic. Body dark, head, thorax, and abdomen with narrow yellow margins.

Paraphrasing Martin Hauser:
If you check the wing venation you will see that Meromacrus has a deep dip in the vein R4+5, while Milesia has just a slight dip there. Compare Meromacrus acutas on the left, with Milesia virginiensis on the right:
Range
Southeastern United States
Habitat
Fields with flowers, etc.
Season
May-September (North Carolina). June-August (Oklahoma). Perhaps absent in mid-summer?
Food
Takes nectar at flowers.
