Bee

Bees are neutral mobs that live in bee nests and beehives. If provoked, bees attack in a swarm to sting the player and inflict poison.

Natural generation
Bees spawn in small groups around bee nests hanging from oak and birch trees found in, and  biomes. Every tree in these biomes has a 5% chance to have a bee nest only during world generation. Bee nests are most commonly found in the Flower Forest biome because of its tree density, as opposed to the few scattered trees found in the other biomes.

Drops
Both baby and adult bees drop no items nor experience upon death, regardless of the cause.

Behavior
Bees fly around their nests, and are attracted by small or tall flowers and sweet berry bushes. After circling a flower for a while a bee can collect pollen. A bee carrying pollen changes its texture to include pollen spots on its back and emits pollen particles.

Bees that have pollen have a chance to pollinate crops they fly over. When a crop is pollinated, it advances to another growth stage, similar to using bone meal. In order to fertilize crops, the pollen particles that fall off the bee have to touch the crop. A bee can fertilize crops only a few times when they have pollen.

When a bee that has pollen enters and then leaves its nest or hive, the honey level of the nest/hive is increased by one. Bees stay in their nest or hive for at least 2400 game tick before coming back out.

Bees follow players holding small flowers. If the player is standing still and being followed by bees, the bees go toward the player, face the player, and rest on the ground. They do this until the player moves.

Bees that enter and then leave their nest/hive keep their data (name, health, etc).

Bees return to their nest when it rains. They do the same when night falls.

As they are arthropods in real life, bees are considered arthropods in Minecraft and take increased damage against the Bane of Arthropods enchantment.

Bees can be attached to a lead, even when angered.

Attacking
Main article: Damage

All bees nearby are angered when one individual is attacked, or when a nest is destroyed. Hitting or walking on a nest does not anger bees; it must be destroyed to anger them.

Bees attack and swarm the player as a group when angered, and the eyes of angered bees turn red, much like wolves. Collecting a honeycomb or a honey bottle from a nest or hive causes the bees from that nest or hive to leave and swarm the player. Placing a campfire below the hive prevents the bees from swarming when comb or honey is harvested. Bees do not attack in Peaceful difficulty.

After attacking and poisoning the player, bees lose their stinger and die within 50–60 seconds. Bees do not attack the player if they have already lost their stinger. Bees can, therefore, attack only once.

Bees also swarm and attack other mobs when damaged, for example, if a skeleton accidentally shoots a bee.

Breeding
If bees are given a flower, they enter love mode and pair off to create baby bees, granting the player a small amount of experience. The parent bees have a cool-down of 5 minutes before they can breed again. Babies take 20 minute to grow up. The growth of baby bees can be accelerated using flowers; each use reduces the remaining time by 10%.

The flower can be any of the 1- or 2-block flowers. The wither rose, which is ordinarily harmful, has no harmful effect when used like this.

Entity data
Bees have entity data associated with them that contains various properties of the mob.

Trivia

 * Bees are the first flying arthropods and first flying neutral mobs introduced to Minecraft. The other arthropods are silverfish, endermites, spiders and cave spiders.
 * Bees are the only arthropod mob that do not count as mobs necessary to earning the Monster Hunter / Monsters Hunted advancements.
 * Creepers and bees are the only mobs that can attack no more than once.
 * Bees were made to be half a block in size since Mojang considered this size to be the cutest.
