When I visited Greece in '92, I noticed that the residential back yards were totally "infested" with the same kinds of snails that the local markets sold.

Like your crickets, they're not .. horrible, if you can stand the rubbery texture when cooked right, but when push comes to shove, that's protein that you can gather with your veggies ...

Though the thought that snails is exactly where dogs get worms from, makes me not want to eat snails.
