Euura viridis (Stephens, 1835)

Euura viridis

The pale colour is green in life fading to yellow in death. The female of this species is similar to viridissimus but markings on the metascutellum differ. In viridis the metascutellum is sometimes entirely pale, often darkened on the hind margin, or with a crescent-shaped dark mark that is sometimes divided into two spots. In viridissimus, the metascutellum is pale with a conspicuous black spot centrally that is round or elliptical. Males of this species have a black mesosternum.

Larvae feed on birches.
