Biology

The larva has been found in rotten wood in cavities in the trunk of Birch Betula sp. and decaying roots of Beech Fagus sylvatica, but is probably associated with a wider range of deciduous species. Adults are usually found in woodland with over-mature trees and are often seen visiting flowers or settled on sun-lit foliage. Males patrol flowers and flowering shrubs. Females can be found flying around the base of stumps and dead or dying trees.
