In common with other members of the genera Cloeon and Procloeon, C. dipterum has a single pair of wings. [3] This is also reflected in the specific epithet dipterum, which is from the Latin di-, meaning two, and the Greek pteron, meaning wing, and in his original description, Carl Linnaeus stated Inferiores alæ vix existunt ("smaller wings hardly present").
