Leopoldius signatus

Alternative names
Ivy Waspgrabber
Description

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. 

Similar Species

L. brevirostris.

Identification difficulty
Recording advice

Unless identified by a recognised expert, a photo is required showing the diagnostic features.

Habitat

Best searched for at Ivy in autumn.

When to see it

Autumn, peaking in September-October.

Life History

Believed to use Common Wasp (Vespula vulgaris) as a host.

UK Status

Widespread across England and Wales, but little recorded. Greater concentration on recording at Ivy in autumn is leading to an increase in records.

VC55 Status

The record from Wood Close Plantation was the first for VC55.
