Hello!
Looks like some Chorthippus. There are many species in the genus, maybe someone knows the species. As for me, they are very difficult for identification (tried many times, but failured

).

In Britain I would have said
Chorthippus albomarginatus (Lesser Marsh Grasshopper) - the pronotal side keels (roughly the line of the division between the straw and green colouration on the thorax) appear fairly straight, and it quite often has this two tone pattern. However, similar species may occur in continental Europe.
