Panorpa communis

This species is native to Europe (mostly) and Northern Asia.[2][3][4]

These scorpionflies can be usually found in hedgerows and patches of nettle.[5]

Panorpa communis can reach a body length of about 30 millimetres (1.2 in).[5] The common scorpionfly has a black and yellow body, with a reddish head and tail. The male has a pair of claspers at the end of its tail (for holding the female during mating),[5] giving it a scorpion-like appearance,[5] although it is not a stinger.

The adult insect has a wingspan of about 35 millimetres (1.4 in),[5] with wings that are mostly clear, but have many dark spots or patches. Its head, mounted with large eyes, is drawn into a prominent, downward pointing beak,[5] which opens at the tip of its head.

In the female, the eighth abdominal segment is the shortest, almost twice shorter than the seventh; the sixth is narrowed towards the back.[6] The larva resembles a caterpillar and grows up to 20 millimetres (0.79 in) long. It has three pairs of thoracic legs and eight pairs of prolegs.[7]

The adult is seen between May and September.[5] They eat dead insects (although they sometimes eat live aphids), sometimes taking them from spider webs[5] and plant sap.[8]

Although fully winged, the adults rarely fly very far and spend much of their time crawling on vegetation in damp, shaded places near water and along hedgerows. Panorpa communis is a univoltine species.[5] Eggs are laid in soil annually and the larvae both scavenge and pupate there.[5]
