Random Insect: Margined leatherwing soldier beetle

Margined leatherwing soldier beetle (Coleoptera: Cantharidae: Chauliognathus marginatus) photographed 06/27/2012 at Side Cut Metropark in Maumee, Ohio.

The other day at Side Cut Metropark near Maumee, Ohio, I found this margined leatherwing soldier beetle (Coleoptera: CantharidaeChauliognathus marginatus) crawling around on a flower. Adults are often found on flowers because most eat nectar and pollen. The larvae, in contrast, eat the eggs and larvae of other insects. Their prey include beetles and moths that are crop pests, so soldier beetles are considered beneficial to humans.

Judging by the photo above, however, it looks like something might have been preying on this leatherwing. The prominent red bump on the right side of the abdomen looks a lot like the egg of a parasitoid wasp or fly. It could also be a pollen grain. It’s hard to tell at this scale.
