Chorthippus vagans - Penumbra Grasshopper
(Eversmann, 1848)

Description: Small, greyish-brown grasshopper (♂ 13-16 mm, ♀ 18-22 mm), the tip of the abdomen is orange-red on the upperside. The tympanon is oval (2x as long as wide), the side keels of the pronotum are bent, the Chorthippus lobe is present. The wings reach to the hind knee. There is no light ring around the knee. The hind tibiae and the underside of the femur are yellow or orange.
Similar species: The Ch. biguttulus-group (Ch. biguttulus, Ch. mollis, Ch. brunneus), but their tympanon is narrower.
Adults: from June to October.
Moderately strong, raspy chirp, which is produced for 15-20 seconds and gradually increases in intensity. There are sometimes very short pauses (less than half a second) within the song. It is similar to the sound of P. parallelus , but it lasts longer.
