According to the BBC news, scientists have rediscovered the bizarre Terrible Hairy Fly (Mormotomyia hirsuta), last seen in 1948 and thought to be extinct. It has the most restricted of habitats, apparently living only in a 20-meter cleft in one rock in Kenya, and breeding on the guano of bats inhabiting the cleft. It’s covered with large bristles and has vestigial wings (evidence for evolution, of course) and tiny eyes.
This is on top of another “rediscovered” fly, Thyreophora cynophila, a bizarre orange-headed creature that breeds on decayed animal corpses. It hadn’t been seen for over 150 years, but in September was reported from two localities in Spain.
