Scotland and northern England. Benson (1958) described it as 'widely distributed' but few records have been found (Musgrove, 2024).
See Liston et al (2017) for determination of adults. The host plant is an upland species.
Euura pustulator larvae feed on Tea-leaved Willow. The gall is in contact with the midrib, projecting equally above and below the leaf-blade. The gall is glabrous and smooth with a single gall per leaf.
