The twin-lobed deerfly is a small horsefly of wet meadows, pastures, swamps and watersides. Adults are summer-active.

Both sexes use flower food, while females also take blood. Males do not blood-feed.

Larvae develop in wet substrate or water and use resources there. Similar deerflies differ in tibial colour and abdominal markings.
