Hamadryas (butterfly)

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.
