Why are some of my dubia roaches white?

Like other insects, dubia roaches regularly shed their exoskeleton (outer shell) as they grow. This is a process called molting. Freshly-molted dubia roaches have soft bodies and look creamy white, but they return to normal within a few hours.
Many reptiles and amphibians enjoy the softness of a freshly-molted roach, so try giving one to your pet as a treat!
