The taxonomic limits of the genus Calliphora are not well defined, with some authors, notably in North America, splitting the group into a number of smaller genera.
The genus Calliphora contains the familiar bluebottle flies, which are easily recognised by their:
Other notable features are:
Calliphora vicina is the most common and widespread bluebottle blowfly in the UK, spatially and seasonally, and is the species most likely to be encountered.
Also common is the rural bluebottle Calliphora vomitoria, which can be easily distinguished from C. vicina by the conspicuous covering of orange hairs on the occiput.
One leading authority on this group has reported that vicina is often confused with uralensis in entomological collections. However, C. uralensis has a dark basicosta, and the anterior thoracic spiracle is also dark.
