Green Grasshopper

Not quite sure yet. The keels on the pronotum look OK but are the forewings possibly extending too far beyond the abdomen for this species? They are also said not to have a costal bulge? There is a prominent bent wing vein here. Is that a costal bulge?

Forewing length can vary quite a bit, and anyway it is inadvisable to compare wing length with abdomen length because the latter may be more or less distended or contracted. It is better to compare wing length against the hind knee. Here it extends slightly beyond that, which is within the normal range of variation. The costal bulge is on the leading edge of the forewing and is characteristic of Chorthippus. Occasional green forms of the Common Field grasshopper bear a superficial resemblance to the Common Green, but the ventral surface of their thorax is profusely hairy, and the wings are never green but buff.
