The facets of an ancient eye

By Gavin Taylor

All that remains of this Eocene fungus gnat, of the tribe Orfeliini, is an endocast in Baltic amber from approximately 40 million years ago. A microCT scan revealed the insects form, and has allowed the surface of its faceted compound eye to be measured. With this information, it is possible to predict how this gnat viewed the forests of the past and also investigate how the eyes of gnats have evolved.
