So does anybody know what the difference is between these nymphs? I’m guessing male/female? It’s obvious they are differently shaped, one has a wider body than the other. The wider ones seem to have less guts to them or a flatter abdomen. I’ve noticed this in my roaches at all sizes from about 3/8” and up. If it is a difference in sex I’m interested to know so I can better select which to feed off and which to keep for breeding. Thanks!
