Chrysomya rufifacies is a species belonging to the blow fly family, Calliphoridae, and is most significant in the field of forensic entomology due to its use in establishing or altering post mortem intervals. The common name for the species is the hairy maggot blow fly, and it belongs to the genus Chrysomya, which is commonly referred to as the Old World screwworms. This genus includes other species such as Chrysomya putoria and Chrysomya bezziana, which are agents of myiasis. C. rufifacies prefers very warm weather and has a relatively short lifecycle. It is widely distributed geographically and prefers to colonize large carcasses over small ones. The species commonly has a greenish metallic appearance and is important medically, economically, and forensically.

Some taxonomists believe C. rufifacies is conspecific with Chrysomya albiceps due to biological, ecological, distributional, and morphological similarities. The larvae of both species are very difficult to distinguish, and only a minor... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Hairy Maggot Blow Fly is recorded against all the insects logged in Phoenix (30 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
