For terms see Morphology of Diptera The species has a wing length of 7–12 mm (0.3–0.5 in). Thorax dorsum with a characteristic "skull" black pattern. Abdomen black with yellow patterning.

Myathropa florea is found in the Palearctic from Fennoscandia south to Iberia and the Mediterranean basin, and from Ireland eastwards across Europe and Russia. It has been adventive on the Pacific coast of North America since 2005.

They occur in deciduous forests, fen carr, farmland with trees, parks, and gardens. They visit many different species of flowers, including umbellifers, Castanea, Convolvulus, Crataegus, Chaerophyllum, Euonymus, Filipendula, Hedera, Rhododendron, Rubus, Sambucus, Solidago, Sorbus, and Viburnum opulus. The flight period is May to October. Larvae feed on bacteria in organic waterlogged detritus, often in the shallow rot holes of tree stumps.
