“Leviticus 11 lists certain species of grasshopper that are permissible for Jews to eat.”
I remember reading that. I read the Torah cover to cover one year.
There are also distinctions about which ones are okay, and which ones are not.
Here’s one translation:
All flying insects that walk on all fours are to be regarded as unclean by you. 21 There are, however, some flying insects that walk on all fours that you may eat: those that have jointed legs for hopping on the ground. 22 Of these you may eat any kind of locust, katydid, cricket or grasshopper. 23 But all other flying insects that have four legs you are to regard as unclean.
Most insects have 6 legs... cannot think of any right now with only 4.
