It's a large, southeast Asian moth wowing the ladies with the intoxicating scent of his inflatable, hairy bits.

They also have a wingspan of some 4 cm (1.6 in), so they're big enough for us to appreciate their spooky beauty. I sure hope they don't do anything to ruin it!
Pretty sure that's Creatos transiens. Ruining it.
From his nether regions, the male inflates two pairs of hairy, pneumatic organs known as coremata. Each one can be about as long as the rest of his body and they're covered in some 3,000 hairs each.
It's all rather nightmarish. It actually looks like a high-speed eruption of that devilish, zombifying fungus known as Cordyceps. But it's not like that at all. In fact, this marks the start of a really great night/sexy times.

Females simply release their scent from their abdomen, none of these inflatable body parts for them. Also, not all males have equally enormous or equally hairy coremata. It all depends on how much POISON they ate when they were young.
for their own use.
Creanotos is similar. Their caterpillars aren't nearly as picky eaters as Monarchs are, but what they really want is lots of plants rich in toxins known as pyrrolizidine alkaloids. This stuff will make caterpillars and adults a lot less appetising to predators, but males also need enough of it to develop their coremata. If they don't get enough, the rest of the moth develops perfectly fine but their coremata will be rather small, not very hairy, and won't produce as much scent.

My thanks to Dimitri for suggesting this one!
