Saimyōshō

The Saimyōshō (Hell Wasps) are Naraku's insects, his demonic wasps. They are used for retrieving Jewel shards, spying on various people, or to prevent Miroku from using his Wind Tunnel, as their poison is deadly. On the weak side for demons, many of them are killed by InuYasha and his friends : only in their numbers lies their strength.

They often accompany Naraku or his incarnations, but will obey Naraku's orders over those of one of his incarnations. They are seldom dangerous by themselves.

Jaken is once poisoned by a Saimyosho, in Jaken Falls Ill, and need Rin to help him recover.

They first appear in Naraku and Sesshomaru Join Forces, as Naraku offers Sesshomaru a hive of them so that he can neutralize Miroku while battling InuYasha.
