The Cratomorphini are a tribe of fireflies within the large subfamily Lampyrinae. The genera placed in this tribe often contain well-sized members of their family. The larvae of many species climb trees to feed on snails. This group includes a few "lightning bugs" (flashing fireflies) from North America, such as the genus Pyractomena. Further south in the American tropics, Aspisoma can be found.
Systematics The group has recently been examined using molecular phylogenetics, using fairly comprehensive sampling.
