Blow fly

Description:

Calliphoridae adults are commonly shiny with metallic colouring, often with blue, green, or black thoraxes and abdomen. Antennae are 3-segmented, aristate. The arista are plumose the entire length, and the second antennal segment is distinctly grooved. Members of Calliphoridae have vein Rs 2-branched, frontal suture present, and well-developed calypters. The characteristics and arrangement of hairs are used to tell the difference between members of this family. All blow-flies have bristles located on the meron. Having two notopleural bristles and a hindmost posthumeral bristle located lateral to pre-sutural bristle are characteristics to look for when identifying this family. The thorax has the continuous dorsal suture across the middle, along with well-defined posterior calli. The post-scutellum is absent or weakly developed. The costa is unbroken and the sub-costa is apparent on the insect
