Grasshopper or Cricket?

I have been on the lookout for grasshoppers all summer . They are masters of disguise, quick and a tease ( making plenty of noise, but being invisible)

I spied this grasshopper in a patch of dry grass it was small . It is a Field grasshopper

What is the difference between grasshoppers and crickets ?

Grasshoppers have short antennae.
Crickets have long antennae.
Grasshoppers stridulate (sing) by rubbing their back legs together.
Crickets stridulate(sing) by rubbing their wings together.
Grasshoppers have ‘ears’ on their abdomen.
Crickets have ‘ears’ on their front legs.
Grasshoppers are out in the day.
Crickets are crepuscular ( they come out at dusk)
Grasshoppers eat plants and grasses.
Crickets also eat animal matter.

They both belong to the order Orthoptera.

When walking the same day on the heath in Ashdown forest I spotted a second even smaller grasshopper that was very green . The photo is not very clear but I was really pleased to see two in one day.
