We found what we believe to be an Edgar's trilobite cockroach in the filter of our turtle tank here at the nature center, but we would like to confirm that since it is unlikely. We ca provide pictures. It has long antennae that are not elbowed nor segmented. From the top, the bug is segmented like a pill bug. It's head is rounded and underneath its top portion. It is brown, gray, and black with distinctive markings. It has three pairs of legs and nothing tail-like.
