What are these weird bugs?

tiny brown hemipteran - Xylocoris cursitans Size: about 1.7 mm,Found in a rearing container that contains several small gro*und beetle species, and adult Eleo*des and a suspected Eleo*des larva -- that just keeps growing!!Although this insect appears flightless, I think it is an adult, otherwise it would not have hemelytra at all.For some reason I think this could be a bedbug for beetles. I noticed that the big larva had several wounds between its tergites (if that's what you call them in a larva), as if something had punctured its skin there. Am I way off base? Please set me straight!! Hope this helps , type the source or go to bugguide.net and find true bugs..
