The Arctiinae (formerly called the Arctiidae) are a large and diverse subfamily of moths, with around 11,000 species found all over the world, including 6,000 neotropical species.[1] This group 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 scientific name of this subfamily refers to this hairiness (Gk. αρκτος = a bear). Caterpillars may also go by the name "tussock moths" (more usually, however, this refers to the Lymantriidae).
