Hello All! I wanted to see what you thought about this strange situation. We currently have 12 T's. Recently, 3 of them began to get bald butts and none of the 3 had been seen "kicking". The T's affected were a T. Vagan (Mexican Red Rump), Tliltocatl Albophiosus (Curly Hair) and a Theraphosa Stirmi (Burgandy Goliath). Sometimes we feed superworms and the worms get away; scooting into the substrate before the T can eat them. They stay hidden for awhile and then morph into big black beetles. None of our T's eat the beetles. Anyhow, the other morning I noticed one of those beetles on the butt of the T. Vagan. I checked all enclosures and found that the 3 T's with balding butts all had the black beetles in their enclosures. None of the other enclosures had them. We rounded up all the black beetles and disposed of them. So, I'm wondering if you guys think that the beetles could have been gnawing on their butts? The uriticating hairs are still present, however the "hide" is gone. All 3 seem okay for the most part; they are eating and moving about. The T Stirmi looks the worst, her butt almost looks raw. Thank you in advance for your thoughts!
