Tiger moths belong to the family Arctiidae which is a large and diverse family of moths with around 11,000 species found all over the world, including 6,000 neotropical species.
The most distinctive feature of the family is a tymbal organ on the metathorax. This organ has membranes which are vibrated to produce ultrasonic sounds. They also have thoracic tympanal organs for hearing, a trait which has a fairly broad distribution in the Lepidoptera, but the location and structure is distinctive to the family. Other distinctive traits are particular setae (‘hairs’) on the larvae, wing venation, and a pair of glands near the ovipositor. The sounds are used in mating and for defense against predators.
