Chorthippus oschei - Carpathian Dancing Grasshopper
Description: Relatively small species (♂ 13-15 mm, ♀ 18-23). Ground colour brown or grey. A light stripe often runs along the lower edge of the female's wing. The side keels of the pronotum are straight. The wings reach more or less the hind knee, but the Chorthippus lobe is not always present. The male abdomen has no red colouration. Field separation from Ch. albomarginatusis not possible.
Similar species: Chorthippus dorsatus, Ch. albomarginatus and Ch. dichrous
Adults: from July to September
Song: The song is rather faint, so the species is often overlooked. It consists of short chirps (0.5 sec), repeated 2-5 times with 2-4 sec intervals. Each chirp starts with a hard sound and at the end stops abruptly. The song is similar to that of Ch. albomarginatus , but the male's courtship song and courtship ritual distinguish the two species.
