Definition
An 'arctiid' is a moth belonging to the former family Arctiidae, now mainly classified under the subfamily Arctiinae within the family Erebidae. Think of it as a label for moths with certain shared characteristics, such as bright colors. These moths often possess unique defense mechanisms against predators. Many arctiids display aposematism or warning coloration. Their caterpillars can be fuzzy, sometimes known as woolly bears. They play a crucial role in various ecosystems, both as caterpillars and moths.
