Systematics

At one time the members of this genus were divided into three

clade A clade (), also known as a monophyletic group or natural group, is a group of organisms that are monophyletic – that is, composed of a common ancestor and all its lineal descendants – on a phylogenetic tree. Rather than the English term, ...

s (''Eristalinus'', ''Eristalodes'' and ''Lathyrophthalmus'') based on morphological characters such as whether the eyes were spotted or striped. Recently Pérez-Bañon ''et al.'' studying the European species of ''Eristalinus'' using a combination of molecular data and male genitalia characters have determined that the genus in Europe at least, divides neatly into two clades - ''Eristalinus'' (+ ''Lathyrophthalmus'') & ''Eristalodes''. It was also discovered that the eye patterning was not taxonomically important as ''Eristalodes'' contained members with eyes either spotted or striped. The following list is an attempt to organise some of the species under subgeneric headings:
