The male did recently pass away, but his lovers consumed the area that we needed for ID. They left the wings and thorax completely intact, but ate the entire abdomen :-(

I am assuming males die after mating, because they never live as long as the females. I was interested in determining the species again, but I guess it is rare to find an intact body when you keep the animals in the same cage

Yet another hazard of working with live omnivores! Even in termite colonies, an injured worker will be consumed quickly, with small lesions expanded by aggressive "grooming." Cockroach behavior is difficult to study, both because they are fairly secretive, and because it is complex, with different species at various stable points between solitary and eusocial patterns. I don't know if the males in this species naturally have such a short life span, or if you've been having bad luck.. Termite kings can live a very long time, and there is not such a great difference in the American cockroaches.

Though you may be disappointed, you are still making good observations, and are gaining experience in insect rearing that is crucial to conducting experiments. You should start making a list of species that you have kept alive and made observations of to include on you CV under the heading of Insect Husbandry. If you don't start the list now, you will have an impossible time trying to remember them all when it comes time to include this. It is more impressive than you realize.
