Tiger and Lichen Moths

Formerly family Arctiidae, this is a large and diverse family of moths with around 11,000 species in three tribes worldwide [2].
This large assemblage also includes footmen, Haploa, and ctenuchid moths.
The most distinctive feature of the family is a tymbal organ on the metathorax which uses a thin membrane to produce ultrasonic countermeasures against their chief predator’s (bats) echolocation system.
Delicate Cycnia Moth
Larvae of some species use sound along with color to advertise their inedibility; many species acquire chemical defenses from their hostplants e.g., milkweeds or dogbane.)

Banded Woolly Bear Caterpillar
Common folklore has it that the forthcoming severity of a winter can be predicted by the amount of black on the Isabella tiger moth’s caterpillar, the most familiar woolly bear in North America; however the relative width of the black band varies among instars, not according to weather (Wagner 2005).
