Blackbottle - Protophormia terraenovae

Alternative names
Northern Blowfly
Description

This is a fairly large, dark blue blowfly. It will often fold its wings tightly over the abdomen at rest which can lead to confusion with the similar Protocalliphora azurea. However P. terraenovae can be separated by its much darker colour and the absence of any dusting on the thorax.
