Distribution
Palaearctic South Fennoscandia southwards to central Spain. Ireland east through Central and South Europe and on through Russia and the Russian Far East to the Pacific coast and Japan and South into China.[9][10]
Occurs particularly in woodlands, on rotten tree-trunks, and on trunks from which sap is flowing. The habitat is Oak and Ash woodland and Hazel scrub, unimproved pastures invaded by scrub (including Rubus and Yew).[11]Arboreal and elusive. In open situations, adults fly along the edge of scrub, often around Rubus fruticosus thickets, on which they settle. Flowers visited include umbellifers, ox-eye daisy, dropwort, Rubus.[12]
The flight period is short - from the end of May into June (July at high altitudes). The larva is believed to be an ant commensal.
