The Slender Blue-winged Grasshopper is a relatively large species with blue-tinged hind wings. The body is brownish to bluish grey, and the species very well camouflaged when resting on lichen-covered rocks. The species mostly occurs in open, coastal situations in the outer part of the Oslo Fiord and along the coast of the Sørlandet region. It is rare and local in Norway.
