Phormia
black blow fly
Phormia is a genus of blow flies in the family Calliphoridae. The genus contains a single species, Phormia regina, commonly known as the black blow fly. This species is native to North America and is among the most important insects in forensic entomology due to its predictable colonization of carrion and well-documented developmental rates. Adults are metallic blue or green in coloration and are distinguished by several morphological features including black gena, mostly white calypters, and orange-yellow anterior thoracic spiracles surrounded by bright orange setae.
