Sifrey (Devarim 103) on Devarim/Deuteronomy 14:19-20 —

You may eat all pure winged creatures —
This is a positive commandment.
And all winged swarming things are taboo to you —
This is a negative commandment.

Ribbí Shim‘on says:
You may eat all pure winged creatures —
Those are pure [=kosher] grasshoppers.
And all winged swarming things are taboo to you, don't eat them —
Those are impure [=nonkosher] grasshoppers.

So eating kosher winged creatures is a positive commandment... and the winged creatures mentioned here may be grasshoppers/locusts. Is this bad news just for vegetarians, or the rest of us too?
