in the Lewis _Biology of Centipedes_ he calls either the last segment or the last two segments the "sexual segments"Yea I see some crazy diff in the terminals on these around here, including the last body segment. Found in central tx, Megalon, North of Austin. Pretty short, fat little pede with a bity attitude.
I get mad when people do that to me . That method sounds familiar. Oh, maybe I'm thinking about herps. Maybe you could drop the pede in some ice cold water for a few minutes or put them in a real tight plastic tube with the last segment or two hanging out. That might be a pretty safe way to try it. If what I see in the polys around here is sexual dimorphism, like I think it is (I have a bad habit of assuming, but it makes sense), it's the most pronounced in any other local species I've seen. I have some good old comparison pics somewhere. Maybe I'll try to dig'em up.in the Lewis _Biology of Centipedes_ he calls either the last segment or the last two segments the "sexual segments"
he even mentions that gently squeezing the last segment on a male will evert the ~penis
