Archaeolepis is the earliest known Lepidopteran fossil. It dates from the Lower Jurassic (ca 190 million years ago) and according to Grimaldi & Engel (2005)[1] a recent re-examination of the specimen has given additional support to its ordinal placement. The fossil consists of a pair of wings with scales that are characteristically similar to the wing venation pattern found in Trichoptera (caddisflies).

The fossil was found in Dorset in the United Kingdom.

The Land Before Time

An Archaeolepis briefly appears in The Land Before Time, where it is chased by Ducky for a short while after she hatches from her egg.
