Pipiza luteitarsis Zetterstedt, 1843Biology
The larva develops on Schizoneura aphids, which curl the leaves of Elm Ulmus sp. This species is associated with deciduous woodland, and adults are often found resting on foliage along the edges of rides and clearings. Males defend patches of sunlight, hovering a few metres above the ground.Distribution
The most distinctive member of the genus that is suited to reliable identification. It is a scarce but widespread species in the southern half of Britain, tending to be recorded more frequently from the east. Whilst its range extends northwards to southern Scotland, it is rare in the northern part of its range. Although listed by Stubbs (1982) as a "good" primary woodland indicator, recent records suggest that it is not confined to ancient woodlands, and the presence of Elm may be a more significant factor.
