Myathropa florea has bold yellow and black markings and gets its common name from the dark outline on the thorax, which resembles the famous Batman symbol. The pattern of grey spots and bars on top of the thorax and yellow body hairs help to identify the species.

A fairly large hoverfly resembling an Eristalis but with distinct grey markings on the thorax (often likened to the Batman logo) and with wing cell R1 open and meeting the costa.

Summer individuals are especially bright; spring ones are usually duller, with more extensive black markings on the abdomen and the paler markings of the abdomen buff-yellow rather than bright lemon-yellow.

These Myathropa florea were seen in June and July 2023 in the gardens of Chiswick House.
