Our insect of the week for November 17, 2025 is the hog sphinx, Darapsa myron [LEPIDOPTERA: Sphingidae]. This species is also known by the common name Virginia Creeper Sphinx. This moth is found throughout eastern and central North America (including central Illinois). It was originally described by the Dutch entomologist Pieter Cramer in 1780. He was a wealthy merchant specializing in linen and Spanish wool.

This species is often found in woodlands and along the edges of woodlands. Larvae prefer to feed on vines such as Virginia creeper, grape, pepper-vine, and related plants. Adults typically fly at night and are often attracted to lights. They can be observed from April through September. Adults often rest on tree trunks and their camouflage makes it difficult to detect them.

Fun fact, no one seems to know where the common name hog sphinx comes from. It does seem a bit odd to combine something related to pigs with something related to Egypt, doesn’t it?
