Corylus habitat in Spain

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).[12] 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.[13]

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.
