Quick Summary

The panorpoid complex refers to a group of insects within the order Mecoptera, commonly known as scorpionflies. This complex is significant in insect phylogeny as it is believed to have provided the origin for several modern insect orders.123

These orders include:
* Scorpionflies (Mecoptera)
* True flies (Diptera)
* Fleas (Siphonaptera)
* Caddisflies (Trichoptera)
* Butterflies and moths (Lepidoptera)3

The term "panorpoid" itself means related to or resembling insects of the order Mecoptera.2

Diptera belong to the panorpoid complex, which includes Mecoptera (scorpionflies), Trichoptera (caddisflies), Lepidoptera (butterflies and moths), Siphonaptera (fleas), and Diptera (true flies). All are believed to have evolved from an ancestor that lived in moss; four-winged insects that resemble
