Species details

Brachypalpoides lentus (Meigen, 1822)

Nomenclature

Xylota lenta Meigen 1822 in Coe (1953), Xylotomima lenta (Meigen, 1822) in Kloet & Hincks (1976).

Biology

The larva of this species develops in the decaying heartwood of Beech Fagus sylvatica, particularly in live trees with exposed decay at ground level. Adults are often seen flying around the base of Beech and Oak Quercus sp. trunks and stumps. They have occasionally been found at Hawthorn Crataegus flowers, and have also been recorded visiting flowers of buttercups Ranunculus sp. There are several records of specimens found indoors on windows in wooded districts.

Distribution

Most records are from lowlands south of Cumbria in England but there are scattered records as far north as Fort William.
