Only recorded in southern England. Benson (1958) felt the species was 'probably common' but was only able to list three counties. Since then, just a single further record has come to light, from Bedfordshire in 2019 (Musgrove, 2024). The type specimen of this species is from Worcester. Both males and females occur. Colouring resembles Euura leucapsis. See Liston et al (2017) for determination.

Larvae feed on Common Osier and Holme Willow. The larvae cause a leaf fold, either spirally twisted or a marginal fold.
