The Isabella tiger moth can be found in many cold and temperate regions. The banded woolly bear larva emerges from the egg in the fall and overwinters in its caterpillar form, by allowing most of its mass to freeze solid. First its heart stops beating, then its gut freezes, then its blood, followed by the rest of the body.
The Woolly Worm Festival is an event held each October since 1978 in Banner Elk and Avery County, North Carolina. [1] The festival celebrates the supposed weather-predicting abilities of the woolly worm, also called "woolly bear" which is a caterpillar or larvae of the isabella tiger moth.
This subfamily includes the groups commonly known as tiger moths (or tigers), which usually have bright colours, footmen, which are usually much drabber, lichen moths, and wasp moths. Many species have "hairy" caterpillars that are popularly known as woolly bears or woolly worms .
The tribe was previously treated as a higher-level taxon, the subfamily Arctiinae, within the lichen and tiger moth family, Arctiidae. The ranks of the family and its subdivisions were lowered in a recent reclassification while keeping the contents of the family and its subdivisions largely unchanged.

Spilosoma virginica is a species of moth in the subfamily Arctiinae occurring in the United States and southern Canada. [3] As a caterpillar, it is known as the yellow woolly bear or yellow bear caterpillar. As an adult, it is known as the Virginian tiger moth.
The garden tiger moth or great tiger moth [2] (Arctia caja) is a moth of the family Erebidae. Arctia caja is a northern species found in the US , Canada , and Europe . [ 3 ] [ 4 ] The moth prefers cold climates with temperate seasonality, as the larvae overwinter, [ 3 ] and preferentially chooses host plants that produce pyrrolizidine alkaloids .
The amount produced, and the size of the coremata which produce it, are however dependent on the diet that the moth experienced as a caterpillar. If the larval diet contained pyrrolizidine alkaloids, then the coremata become large and the male will release up to 400 micrograms (0.4 milligrams) of hydroxydanaidal, but if it does not, then the ...
