EUURA MYOSOTIDIS GROUP

Euura albipennis - Whitewing Redshank Nematine

Nematus albipennis Hartig, 1837
Polynematus albipennis (Hartig, 1837)
Nematus obscuratus Zaddach, 1883
Pachynematus legirupus Konow, 1903
Pachynematus sannio Konow, 1903

North to southern Scotland. Rather seldom recorded, although seemingly widespread and potentially overlooked. Foodplant is ubiquitous except on highest ground. The lack of records since 2011 is noteworthy given that previous records have been made quite widely and largely in absence of dedicated survey of specific habitats (Musgrove, 2024).

This species is very similar to Euura bipartita. The head is mainly black with black inner orbits. The abdomen is yellow with at most the first tergite black marked. The scutellum is coarsley punctured. The hind femora are pale yellow more or less infuscated from the base.

Euura albipennis larvae feed on the underside of rolled leaves of redshank.

Size: 4.5 - 5.5mm.

GB IUCN Status: Vulnerable
GB Rarity Status: None

Distribution: England, Scotland, Wales, Ireland

Flight period: May to June, July to August
