Calliphora livida
slow-flying and loud-buzzing blue bottle fly
Calliphora livida is a blow fly in the family Calliphoridae, commonly known as blue bottle flies. It is a medium-sized fly with a blue metallic sheen dulled by dense micromentum. The species is widespread across North America and is notable for its relatively delayed arrival on carrion compared to other blow flies, typically appearing approximately 24 hours after death. It prefers cooler, shaded environments with temperatures ranging from 4 to 15.6°C. The species holds significant forensic importance for post-mortem interval estimation, particularly during spring and colder months when other blow fly species may be less active.
Calliphora terraenovae
New World blue bottle fly
Calliphora terraenovae is a species of blow fly in the family Calliphoridae, commonly known as the New World blue bottle fly. It is native to North America and serves as an important decomposer in forensic entomology investigations. The species is closely related to other blue bottle flies in the genus Calliphora, including the widespread Palearctic species C. vicina, with which it shares ecological and morphological similarities.
