From Science News via Wired Science:

… Scientists have found a tiny fly with a three-pronged horn and spiky
eyes preserved in a chunk of amber dating to roughly 100 million years
ago. The fly has been named Cascoplecia insolitis (Casco meaning old and insolitis
for strange, unusual) and is so bizarre that that it has been assigned
to a new insect family, reports George Poinar, Jr. of Oregon State
University in Corvallis…. Photographs and a description of the specimen will appear in an upcoming issue of Cretaceous Research….
