Nematus leucostictus Hartig, 1837
Phyllocolpa leucosticta (Hartig, 1837)
Nematus crassulus Thomson, 1863
Nematus sharpi Cameron, 1876
Nematus erythropygus Förster, 1854
North to northern Scotland, seemingly common and widespread (Musgrove, 2024).
The species shows some variability in colour. See Liston et al (2017) for determination.
Euura leucosticta larvae feed on Grey Willow, Eared Willow and Goat Willow. The larvae cause a leaf fold, either spirally twisted or a marginal fold.
