Mite (Dungeons & Dragons)
The mite appeared in second edition Advanced Dungeons & Dragons for the Greyhawk setting in the Monstrous Compendium Greyhawk Appendix (1990). The mite appeared under the "gremlin" heading in the Monstrous Manual (1993).
A mite is a tiny, mischievous, wingless humanoid that waylays dungeons adventurers for fun and profit. Mites are small and quick, scurrying to and fro through their interconnecting tunnels. They use traps to catch lone travelers, who they swarm over and pummel with weighted clubs to stun them and torment them for days until the mites get bored.
