Cascoplecia insolitis, rarely known as the unicorn fly,[1] is an extinct dipteran that lived in the Early Cretaceous. The type specimen was found in Burmese amber.[1] George Poinar Jr., who described the fossil, placed the genus into a new family Cascopleciidae. One of the defining characteristics of Cascoplecia is the presence of three ocelli raised on an extended, horn-like protuberance. The distinctiveness of the family was questioned by other authors, and the genus has been subsequently transferred to the family Bibionidae.[2][3]
