flies I found in the backyard. Here are a few more. The one pictured above is a blow fly, probably a Common Green Bottle Fly (Lucilia sericata). This is a very common species, recognized by its metallic coloration and the pattern of hairs on its thorax. According to Wikipedia, the larvae of this species are sometimes used for maggot therapy. Lucilia sericata is also one of several species that help establish how long a corpse has been dead, since the flies lay their eggs and the larvae develop in a predictable sequence. When not scavenging at corpses, blow flies can be useful pollinators.
