Tiger Moth - Creatonotos gangis
What you see in this photo is a male of Creatonotos gangis (Arctiidae), a species of Asian moth, showing his expanded pheromone diffuser structures at the tip of the abdomen (called coremata and androconia). The four coremata are reversible, each when inflated may be longer than the abdomen.
Females pheromonally attract males from long distances, however, when the male is close enough to begin his courtship, he inflates his coremata with air or hemolymph to evert externally from the abdomen and fans pheromones of his own towards the female.
This species of moth is found over much of south-east Asia, as well as in Australia.

“Hi there. I’m a bat of the pipistrelle sort. Hope you are too. I’m a guy. You’re a gal. Let’s get together and do what we bats like to do. I’m sure you know what I’m talking about. We have so much in common. Come a little closer…”
“Hello Commander Hadfield, for the past year and a half my 5-year-old son goes to bed worried, sometimes in tears. He is worried about the Voyager Interstellar spacecraft, the fact that it is out there all by itself. He wants it to come home to be safe. What do we tell him?”
“I’ve never been certain whether the moral of the Icarus story should only be, as is generally accepted, ‘don’t try to fly too high,’ or whether it might also be thought of as ‘forget the wax and feathers, and do a better job on the wings.’”
