Tarsonemus woodi

Acarapis woodi, commonly called the honey bee tracheal mite (HBTM), is an internal parasite specific to honey bees. These mites are generally less than 175 micrometres (0.007 in) long, and can only be identified under a microscope.[1]

A. woodi live in the breathing (tracheal) tubes of adult honey bees, and only move outside the host to infest other bees.[2] Female mites attach 5–7 eggs to the tracheal walls, where the larvae hatch and develop into adult mites within 11–15 days.[1] The mites parasitize young bees up to two weeks old, targeting their tracheal tube openings. Once there, the mites pierce the tracheal tube wall using their mouthparts, and feed on the host bee's haemolymph.

Two other parasitic bee mites resembling the tracheal mite are A. dorsalis and A. externus.
