Adult habitat & habits
Flies up to 2m from ground within woodland, rarely coming out into direct sunlight; can be found in dappled sunlight at the edge of clearings, in glades, along tracks, beside streams etc.; usually near water; visits flowers in the shade, as much as in sunlight.
May/September, with peaks in May/June and August. Larva: described and figured by Hartley (1961), from larvae found in wet, sappy material beneath a patch of wet bark on a living Ulmus. Larvae have also been found under the bark of water-logged branches of various deciduous trees and in sap runs on Quercus, e.g. by Rotheray (1990a), indicating that this species is not dependent upon sap-runs for larval development. S. clunipes has also been collected in emergence traps installed over flushes under the tree canopy of an Alnus wood. Rotheray (1994) illustrates the larva in colour.

See Key to males provided in StN Keys volume andThompson & Torp (1986), who figure the male terminalia. The adult insect is illustrated in colour by Bartsch et al (2009b), Stubbs and Falk (1983) and Torp (1994).
From Fennoscandia south to Iberia; from Ireland eastwards through most of Europe into European parts of Russia and the Caucasus; through Siberia to the Pacific coast; Japan. It is probably the most frequently encountered species of the genus in most parts of Europe, and occurs in wooded situations from northern Norway to the Mediterranean. It also ranges widely in Asiatic parts of the Palaearctic.
Recorded as occurring in Ireland in Coe (1953). S. clunipes is widely distributed and frequent in Ireland.
