Odd discoid coloration

Recommended Posts

This male Blaberus discoidalis molted out last week and I thought the pronotum coloration would fade after it hardened. I was cleaning the tank today and noticed he still looked like this. Any clues? I'm used to them being nearly 100% black on the pronotum markings.

Could be a hybrid, a "throwback" gene due to common Blaberus ancestry, diet, or injury to the roach while it was younger/ overcrowding that caused hypopigmentation. If the coloration of your other discoids is pretty consistent you may want to isolate this one and try and breed for that color.

Ooh, weird. Although as Zephyr said it may not be genetic, I'd still try to isolate it!

Kyle is correct. They were hybrids and have since been disposed of. My friends monitor enjoyed them. Heh. The pure stock was very slow to breed by comparison but much more consistent in their coloration.
