Hamadryas laodamia, the starry night cracker or starry cracker, is a species of cracker butterfly in the family Nymphalidae. [1] It can be found from Mexico to the Amazon basin, but is most common in lowland forest in the Caribbean area.


The starry night cracker is a black butterfly with iridescent blue speckling on its wings. The female has a white band on the underside of the forewing that is broader than the band on the male. [2] The wingspan is about 7 cm (2.8 in). [3] The caterpillars have short horns on their heads, the function of which is unknown, and the pupae are bright green. [2]
