Got stung by a bee on the back of the head

Got stung by a bee randomly this morning on the back of my head going for a walk. Reacted and flailed my arms and lost my glasses because they flew off and I was running. Didnt leave me alone for like 5 minutes. F*** Bees.

What couldve cause this, I think it may have been from a new cologn I got that attracted it/them?
