Cheilosia uviformis Becker, 1894

Identification

Identification difficulty = 5. microscope_icon camera_icon_cross according to Ball & Morris, 20241

Synonymy

Cheilosia argentifrons Hellén, 1914.

Biology

The larva remains undescribed. Speight (1988)2 concludes that this species is associated with deciduous woodland, and in most cases with areas that are seasonally flooded. Males hover 7-10m above the ground, and females have been found sitting inconspicuously on tussocks of dead grass. Adults visit spring-flowering shrubs such as sallows Salix sp. and Hawthorn Crataegus sp.

Status

DATA DEFICIENT - Ball & Morris, 20143.

Distribution

Originally found in Ireland in 1985, it has subsequently been found in Scotland, Yorkshire and Derbyshire (Stubbs, 1996[^UKP3LFL6

]; Speight, 19864; Whiteley, 19885). There are too few records as yet to allow any interpretation of its status and distribution. dotmap
