Bee

The are a species of bees that are bred and utilized exclusively by the Kamizuru clan as the focal point of their unique techniques. The ninhachi have only appeared in the anime-only Search for the Bikōchū Arc. Unlike the kikaichū, the insects used by the Kamizuru's rival, the Aburame clan, the ninja bees are summoned into battle. They are also capable of growing to large sizes, as seen with the Giant Bee. Their larva form have the ability just like the Aburame clan bugs to eat chakra.

The ninja bees' usefulness centers around offensive capabilities of their stings, with attacks like the Thousand Bee Stings Technique. They are used frivolously in tactics where the bees' lives are sacrificed without concern for their survival; techniques like Jibachi's Bee Bomb Technique shows the bees being sent to attack with exploding tags attached to them.

Trivia

 * Despite their name, looking at them closely reveals that they are not bees, but rather Vespa mandarinia, the Asian Giant Hornet.
 * As proof of this not only their appearance is similar but also when Shino held one of them on his hand, one can see it is far larger than a normal bee.
