Stenobothrus Fischer

Excluding Chorthippus.

Adults diurnal; 10–15 mm long (S. stigmaticus), or 15–23 mm long (S. lineatus; the females somewhat the larger in both species); usually green, sometimes with brownish forewings and brown marks elsewhere, but females sometimes pinkish or purplish; usually with a white line on the front edges of the forewings; males often developing orange colouration of the abdomen and hind tibiae.

The antennae relatively short, with fewer than 30 segments; not thickened towards the tip. The pronotum not extended backwards over the abdomen. Forewings well developed; about equalling the abdomen (neither much longer nor much shorter). The costal margin of the forewing straight, the wing narrowing gradually with no basal dilation. Hindwings fully developed and functional for flight; not pale blue. Foreleg tarsi 3 segmented; mid-leg tarsi 3 segmented; hindleg tarsi 3 segmented. The hind femora keeled. Hind tibiae not banded black and yellow. The ovipositor relatively short, and consisting of separate, prong-like valves articulated at the base; valves armed on the outer side with a strong tooth orientated in the same direction as their points. The males stridulous. The sound production of the males femoro-alary, involving rubbing the rough insides of the hind femora against prominent veins in the forewings. Auditory organs located in the first abdominal segment (sometimes concealed by the folded wings or the hind-legs, and the tympanal cavity sometimes partially covered by a flap).

British representation. 2 species. Stenobothrus lineatus (Stripe-winged Grasshopper), S. stigmaticus (Lesser Mottled Grasshopper). Native. Southeast England, central southern England, southwest England, and Isle of Wight (S. lineatus), or English Midlands (Isle of Man only, S. stigmaticus).

Vegetarian (feeding mainly on gasses); found outdoors in natural habitats (on thin turf).

Classification. Suborder Caelifera; Superfamily Acridoidea; Acrididae.
