Creatonotos gangis
This very real moth found in South East Asia and part of Australia has been making the rounds on the internet thanks to a viral video made popular by The Independent.
The “thing” on its abdomen is called a coremata and is used to produce a pheromone called hydroxydanaidal to attract mates. Some males can produce up to 400 milligrams of the pheromone. The size of the coremata and the amount of hydroxydanaidal produced depends on the diet of the insect in its caterpillar stage and if the diet included pyrrolizidine alkaloids.
