Species details
Cheilosia longula (Zetterstedt, 1838)
BiologyThe larva develops in the fruiting bodies of large fungi including Boletus, Suillus and Leccinum. With up to 50 larvae having been found in a fungal cap, the fruiting body loses shape and forms a deliquescent mass on the ground. Adults are usually found along woodland (deciduous and coniferous) edges and rides, or in glades where they can often be found on sun-lit vegetation. A range of flowers including white umbels and yellow composites are visited.
DistributionThis species is widely distributed throughout Britain. It mainly occurs in acidic, sandy locations, especially heathland and moorlands. There are comparatively few records from well-recorded parts of the English Midlands, which are generally less acidic and support richer soils.
