Update!
Cercropias are doing great. Big monsters! Cercropia have always been my favorite they are so neat looking and they have crazy feet. Their grip is amazing. You can't pull them off because, they stick like glue.
Monarchs are also doing well. I caught one today turning into a chrysalis which is a process I've never seen before. I have about a dozen of these guys now. In a few days half of them will be chrysalises. Here are pics from the changing process. Kinda gross, yet pretty fascinating. I swear I can see a butterfly in it when I look at the pics. Also caterpillars are the masters of pooping. That is a 2.5 gal tank. 4 mature monarchs, some leaves, and 48 hours = a ton of poop.
Finally it appears I am starting a collection. Cuz now there is a third type I have picked up. I'm not sure on a exact ID yet, but I have a guess. It's gonna stay a mystery though. This caterpillar is sorely out classed in pretty looks.
