I noticed I have been having dubias dying in one of my colony's. The colony has about 500-600 roaches and I've been finding about 3-6 dead roaches per day (all large nymphs and adults)
I found it very unusual that each roach that died had one rear leg missing and the joint where the leg was connected looked very black like necrosis. Also the abdomens are swelled.
I also found some roaches with all legs in tact but the legs were black and rotten looking (necrosis)
Anyone ever heard of this issue? (If it even is a issue)
