Calliphoridae

Calliphoridae (commonly known as blow-flies, carrion flies, bluebottles, greenbottles, or cluster flies) are insects in the Order Diptera, family Calliphoridae with 1,100 known species. The family is known to be non-monophyletic, but much remains disputed regarding proper treatment of the constituent units, some of which are occasionally accorded family status (e.g., Bengaliidae, Helicoboscidae, Polleniidae, Rhiniidae).

The name blow-fly comes from an older English term for meat that had eggs laid on it, which was said to be fly blown. The first known association of the term "blow" with flies appears in the plays of William Shakespeare: Love's Labour's Lost, The Tempest, and Antony and Cleopatra.
