These guys have been really abundant on a variety of spring wildflowers, especially cinquefoil as seen here. I'm unsure whether they are consuming the nectar or the actual flowers, since many of the blossoms show signs of being nibbled by something.

Yep...
...adults of this genus feed on petals and pollen. I don't think they are attracted to nectar, per se, since they visit a large variety of flowers that don't offer nectar, and they lack the modified (elongated) mouthparts necessary to get at nectar in many flowers. This species and the similar A. neglecta (south-central US) are especially fond of cinquefoil petals - also Ruellia and Taraxicum.
