Small metallic black beetle with long antennae - Diabrotica cristata
Bunker Hill Forest Preserve, Chicago, Cook County, Illinois, USA
August 16, 2008
Size: ~4mm
Most of these beetles seemed to be hanging out on big bluestem grass, Andropogon gerardii, but there were a few that were on Liatris spicata, such as here, and some on Eryngium yuccifolium. Do they feed on leaves or nectar or both?!
