Calliphora vomitoria-vicina
Common & widespread in Britain, partially buzzing nosily in some houses during the Summer.
Flies from May-September.
Known as a blue bottle fly because of the metallic blue-gray coloration of its thorax and abdomen.
It is distinguished from the commonly known C. vomitoria by its bright orange cheeks.
The Blue bottle fly is approximately 10–11 mm in length.
The similarities between the different species of Calliphora can make identification of immature stages nearly impossible.
From the first instar to the pupa stage C. vicina is identical to that of C. vomitoria.
