Collected ten of the individuals that came pouring out of a cow spine I found along a dirt road and whacked several times on the ground to break apart. Before I had a firm ID I had a good idea these were clerids -- not just by their appearance but by their behavior. They settled right down to eating dead bugs and gnats among the small specimens I had sucked up with my aspirator, and I saw one attack a smaller beetle that later died. They held their food in their front pair or front two pairs of legs the way I had seen another clerid do. On occasion they used all six legs.
