An oldie:
Back in 2005 I found several of the Polysarca denticauda (Orthoptera; Tettigoniidae; Wanstschrecke) in the Bjelašnica mountains south of Sarajevo. The animals protect their stubby wings (with which the males make sounds) with the extended prothorax. I took the picture with an Olympus compact camera at about 1'200 m a.s.l. Surprisingly, some minutes before this shot was taken we saw two wolves crossing our path. The mountains are quite deserted, the karstic soil is just good enough for pasturing sheep. The forests are still dangerous because of personal mines, leftovers from the cruel civil war. But with the help of a local guide you can wander around off the paths safely.

ID of this 30 mm long male was erroneous at first, I had arrived at Psorodonotus illyricus and named the picture accordingly, sorry for that. As Jo Sk from Croatia pointed out, the subgenital plate clearly extends up between the cerci, excluding Psorodonotus. I used H. Bellmann, 2006. Der Kosmos Heuschreckenführer. Franckh-Kosmos Verlag Stuttgart Germany and a publication of R. Ebner, 1923 (www.landesmuseum.at/pdf_frei_remote/KON_2_0249-0256.pdf)

Hi,
this is not Psorodonotus illyricus, but Polysarcus denticauda. Look at the hind leg tibia/tarsus connection, there are no movable flaps. Also, look the pronotum shape - it is not characteristic of P. illyricus. And the last and the most important thing is subgenital plate passing abobe cerci, what is not the case in P. illyricus.

Sincerely,
JS
