Inflation of Moth Coremata

Description:  This viral video (with added sound effect) shows an entomologist inflating the coremata in a recently deceased male moth. This pheromone-producing organ will normally sit inside the moth but will be used during courtship to attract potential mates. It is inflated with blood or air. This phenomenon could be used as an example of how organisms increase their change of reproduction through internal and external structures.
