Leopoldius signatus
Whilst superficially resembling Conops species, Leopoldius species can be immediately recognised by their soft proboscis, nothing like the long sclerotised mouthparts found in Conops.
There are only two predominantly yellow British species. Males of L. signatus can be separated by genitalia differences, a lack of black facial markings, and black-ringed hind femora. Females by 3 triangular projections from the hind margins of the black bands on tergites 2-4.
L. brevirostris.
Unless identified by a recognised expert, a photo is required showing the diagnostic features.
Best searched for at Ivy in autumn.
Autumn, peaking in September-October.
Believed to use Common Wasp (Vespula vulgaris) as a host.
Widespread across England and Wales, but little recorded. Greater concentration on recording at Ivy in autumn is leading to an increase in records.
The record from Wood Close Plantation was the first for VC55.
