Archaeolepis mane is the earliest known Lepidopteran fossil. It dates from the Lower Jurassic (ca 190 million years ago) and according to Grimaldi & Engel (2005) 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.
