Adults diurnal; 12–15 mm long (males), or 13–19 mm long (females); variously coloured: forewings usually brownish and never green, the other body parts varying from green through brown to dark purple.
The antennae relatively short, with fewer than 30 segments; thickened towards the tip (more markedly clubbed in the male). The antennal tips not white (by contrast with Gomphoserippus). Forewings well developed; about equalling the abdomen (neither much longer nor much shorter) to much shorter than the abdomen (not much shorter). The costal margin of the forewing straight, the wing narrowing gradually with no basal dilation. Hindwings fully developed and functional for flight. Foreleg tarsi 3 segmented; mid-leg tarsi 3 segmented; hindleg tarsi 3 segmented. The hind femora keeled. The ovipositor relatively short, and consisting of separate, prong-like valves articulated at the base. 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. 1 species. Myrmeleotettix maculatus (Mottled Grasshopper). Native. Northern Scotland, southern Scotland, northern England, English Midlands, East Anglia, Wales, southeast England, central southern England, southwest England, Isle of Wight, and Ireland.
Vegetarian (feeding mainly on gasses); found outdoors in natural habitats (mostly associated with short turf, in dry situations).
Classification. Suborder Caelifera; Superfamily Acridoidea; Acrididae.

We advise against extracting comparative information from the descriptions. This is much more easily achieved using the DELTA data files or the interactive key, which allows access to the character list, illustrations, full and partial descriptions, diagnostic descriptions, differences and similarities between taxa, lists of taxa exhibiting or lacking specified attributes, and distributions of character states within any set of taxa. See also Guidelines for using data taken from Web publications.
