Sawfly - Green Sawfly

Shop
Rhogogaster scalaris
Common & widespread in Britain.
Flies from May-August.
Like other species in its genus, this sawfly has a light green head and body.
The black markings on the head form two loops in a ∞-shape with two green, rectangular marks in front of the posterior ocelli.
The wings are transparent, with the pterostigma uniformly yellowish-green.
The legs are green with black bands.
This species is separated from the allied R. scalaris in part by the entirely green, rather than black, postocellar carina and from R. polaris in part by the more strongly convex mesoscutellum.
As in other sawflies, the Female has a saw-like ovipositor.
