Dubias with missing legs dying necrosis

[RoachBreeder]

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)

I would assume that your roaches had died first from improper conditions of some sort and then started rotting. Many insects rot almost instantly after death.

They stopped doing it after a few days... I had ordered a pound of dubia from dubiadeli and I guess some must have been stressed from the shipping.  thanks for the answer!
