The Environmental Records Centre for Cornwall and the Isles of Scilly has some useful resources for identification of Orthoptera (grasshoppers, crickets etc.). Their main page is at:
which has some useful background info, but they also provide guides, with sound clips, to the calls of crickets and grasshoppers:
Personally I find it easier to identify many of these insects from their calls than from looking at them, so this could be a very helpful resource. But we'll have to wait until next summer to make use of it now!
