Calliphoridae - Blow Fly
Northern Sierra Nevada, California, USA
Calliphorid flies are usually among the first insects to arrive at a fresh carcass, where they mate and lay eggs on the recently dead animal. These flies play important roles in terrestrial ecosystems as recyclers of animal biomass. Calliphorids are also directly relevant to human affairs, as they are sometimes collected by forensic entomologists from human remains to help determine time of death.
