Minecraft wiki entry for Bee, associated text: Bees attack and swarm the player as a group when angered, and the eyes of angered bees turn red. Collecting a honeycomb or a honey bottle from a nest or hive causes the bees that are currently in that nest or hive to leave and swarm the player unless a campfire is placed below the hive. Bees attack only once, similar to llamas, and non-aggressive pandas. Bees do not deal any damage in Peaceful difficulty.
