Myrmeleotettix maculatus - Common Club Grasshopper
(Thunberg, 1815)

Description: Small but robust species (♂ 10-15 mm, ♀ 11-16 mm). The male's antennae with a dark club and curved outwards. Several colour variations are known (green, brown, black). The wings reach to about the end of the abdomen. The side keels of the pronotum are angularly curved. Identification of the female is more difficult because the club of the antenna is not as conspicuous.
Similar species: Myrmeleotettix antennatus, Omocestus haemorrhoidalis, Omocestus petraeus
Adults: from June to October.
The song consists of 10-20 chirps, each chirp lasting about 0.5 seconds, with intervals of about 0.5 sec. There are quite long pauses between two songs.
