There was a very interesting segment on Vikings, (S5/ep3 "Homeland") in which a dying Floki has a vision.
One of the figures in the vision is a dark robed woman, who opens her mouth to release a swarm of bees.
The close-up shot of the woman's face gave the distinct impression of necrotic flesh, so my assumption was it was probably Hel. I found this great article on Hel, but no mention of bees, and another great article on bees and the goddess, but no mention of Hel.
Extra points for any thoughts on the second woman in the vision, who transformed into a murder of crows.
