The thorax, wiggling around like a creep on the dance floor. But fear is an irrational reaction, it's our instinctive response to the unknown. Knowledge is the antidote. Let's learn a little bit about our little friend, the Creatonotos gangis.
Those four wiggling nightmares sprouting from its butt aren't so scary, they're just uh... sex tubes for attracting mates. You see they... inflate with sex pheromone juices that are... uh... secreted by the male. According to Boppre and Schneider in the Zoological Journal of the Linnean Society, "The reproductive biology of the arctiid moths Creatonotos transiens and C. gangis exhibits a novel ontogenetic phenomenon, the morphogenesis of male coremata size being directly controlled by the quantity of hostplant-derived pyrrolizidine alkaloids ingested by the larvae."
I don't know what half of those words mean, and I still threw up in my mouth. Maybe the paper gets less graphic. Let's see, "The males possess inflatable androconial organs..." hurp alright that's pretty gross, skipping ahead here... "The larvae of both species are brown and very hairy..." UGH. Okay, okay. Let's all take a deep breath. They can't help how they're born, appearances aren't everything, and--
