Seeking for help with identifying of an insect

[Moderator64]

I need some help identifying a bug. I took a picture with my phone when observing it through a dissection microscope. It's about 4-6mm in length and I'm currently storing it in spiritus so it won't spoil (or so I've been told it works like this). The insect is gray on the outside. It was found in grass in Poland by the beach in a place called Hel (just next to the Baltic Sea). I'd like to try and dissect it, but I want to know who will be the subject of my experiment. Any help will be gladly appreciated.
