Cockroach Mating Call

I found this impressively large two inch long cockroach just like this, sticking out its abdomen from the side of a creek bank after dark. I found the behavior odd, and I suspected that it might be releasing pheromones to attract a mate. I really had no idea if cockroaches did that or not. After some recent reading, that does appear to be part of the courtship ritual. To initiate courtship, a female will call nearby males in this manner. Presumably then, this is a female.

A while later, I managed to catch her in a different pose.

Another pose

Checking the plates of the Electronic Biologia Centrali-Americana, I wonder if this might be Cacoblatta scabra (or a related species) from this plate.

      I probably encountered it before and forgot about it. Patrick Coin brought it to my attention in a recent comment and I’m finding it quite useful.
