No. Once bees are endangered, the resulting ecological collapse will have made the rule of law obsolete.

I have no idea how protection for endangered colony insects works, but it might make the most sense to just protect the hive and queen instead of every individual colony member.

if you’re at a point where they’re stinging you you’re probably doing something that would be considered illegal already

Try reading a bee its rights as it lays dying. They do not listen.

When bees become an endangered species, would it be illegal if one were to sting you?

In this hypothetical system, bees would become akin to cops where it would be up to themselves to enforce rules, moral/ethics, and systems.
