Lucilia bufonivora
Lucilia bufonivora
Identification: Very similar to L. silvarum and L. elongata . Previously unreported in North America, this species was absent from calliphorid keys, leading to reports of Anuran myiasis from the previously mentioned species. This species is included

Bird Blowfly
Protocalliphora azurea
Length 7-12mm. A dark metallic blue blowfly. It is distinguished from Protophormia terraenovae by the presence of long presutural acrostichals and dusting on the thorax. Good quality dorsal and lateral photographs showing the distinguishing features

Blackbottle
Protophormia terraenovae
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 a
