I don't know about crickets, but the wilds of Bolton were full of

No these are quite robust - a good couple of inches long, bright green
with green wing cases and very long antennae. They are the noisiest of
our native crickets and can make quite a racket when they're at full
pelt ... as they were for several hours last night :|
