Heraclia busiris (Fabricius)

Lost Heraclia Moth (Heraclia busiris)

This species is known from a single specimen that was collected somewhere in Africa (all other known members of the genus occur there); it was described in 1793, originally as a skipper (Hesperidae).

The sole specimen was examined in 2018, when it was found not to be a skipper (Hesperiidae) at all but instead a member of a completely different family, the owlet moths (Noctuidae). [1]

The Lost Heraclia Moth has not been found for 229 years; it may well be lost forever.
