(Thunberg, 1815)

Description: Small species (♂ 13-18 mm, ♀ 17-25 mm). It has several colour variations, similar in all characters to Ch. biguttulus and Ch. mollis, the male's sound is the only way to distinguish them in the field. The wings are long, extending well beyond the hind knee, and the Chorthippus lobe on the male fore wing is barely visible.
Similar species: The Ch. biguttulus-group (Ch. biguttulus, Ch. mollis, Ch. brunneus), these species are very similar to each other. Best identification is by listening to the male's calling song.
Adults: from June to October.
A series of short, strong chirps (about 0.1-0.3 sec. long) repeated 6-12 times with 1 to 2 second intervals. The sound is hearable up to 10 m.
