Bees

Bees are small flying inspects that attack in swarms. (The Darkest Hour) A swarm of bees were implied to be attacking Gwaine in the forest, but were not physically seen and he seemed only bothered and not harmed by them. Bees, in Merlin's age, were probably the same as they are in this age, with the same instincts and habits, plus variety. The bees encountered, most likely by intruding in a bee's territory, or nearby where their base was, were not deadly and only seen a nuisance pest. Bees have only appeared in one part of The Darkest Hour and have not been mentioned since.
