These are sure puzzling creatures, and we cannot devote the time we would like to their identification at this moment. We are posting your images and we hope to hear from our readers while we do additional research. Are you able to provide any information on their size?
Update: We suspected these were Crustaceans. We wrote to Eric Eaton who wrote back “Some kind of amphipod, not sure beyond that as they are not insects nor arachnids.” In researching Freshwater Isopods, we found these image of a cave dwelling Isopod on Encyclopedia of Arkansas, and since there are numerous caves in Kentucky, we speculated that it would be easy for some cave species to survive in a sewer.
