Euura venusta - amerinae group
See Liston et al (2017) for determination of adults. The host plants are mostly widespread species. Within this group, males of Euura mucronata, Euura testaceipes and Euura venusta are inseparable.
Euura venusta larvae feed on leaves of eared willow, goat willow, downy willow and grey willows causing a spindle shaped swelling in the leaf petiole. Usually one gall per leaf.
