A hamadryad or hamadryas is a Greek mythological being that lives in trees. It is a particular type of dryad which, in turn, is a particular type of nymph. Hamadryads are born bonded to a certain tree on which its life depends. Some maintain that a hamadryad is the tree itself, with a normal dryad being simply the indwelling entity, or spirit, of the tree. If the tree should die, the hamadryad associated with it would die as well. For this reason, both dryads and the other gods would punish mortals who harmed trees.
Cracker butterflies are a Neotropical group of medium-sized brush-footed butterfly species of the genus Hamadryas. They acquired their common name due to the unusual way that males produce a "cracking" sound as part of their territorial displays. The most comprehensive work about their ecology and behavior is that of Julian Monge Najera et al. (1998). The genus was erected by Jacob Hübner in 1806.
