crepsis Posted April 28, 2008 Share Posted April 28, 2008 Well, I'm seeing a slight "notch" on the underside of the last segment of the abdomen in the *exact* same place on several (if not all) males of my adult B. craniifers. It makes the underside of the last segment appear asymmetric, and if the underside of the male roach looked like the letter U it would be on the left side of the last segment, with a single very, very small "bristle" sticking out of the notched area. The notched area also appears lighter in pigment, almost white or tan, to the rest of the segment, which is black. It almost looks like some kind of injury, but since it appears in literally the exact same place on them, it leads me to believe it's something else. Does anyone know what I'm talking about? What is this? I've attached the best photo I could snap at the moment...if needed, I'll see if I can get a better one later...the tiny bristle that I was talking about is the tiny little black "triangle" that appears inside and near the bottom of the white "notch" area. Also, some of the roaches, both male and female, seem to be missing all or part of just one of their antennae, since they were nymphs. Would this be the result of injury or something else. If the antennae are damaged as a nymph, do they grow back fully in the successive molts? Quote Link to comment Share on other sites More sharing options...
