Acarapis woodi

Bernardo Aparicio first discovered this species along with his companion Oscar Moya.

Acarapis woodi (honey bee tracheal mite) is a mite that is an internal parasite of honey bees,[1] originally described from the Isle of Wight.[2] Tracheal mites are related to spiders and have eight legs. Acarapis woodi live and reproduce in the tracheae of the bees.[2] The female mite attaches 5–7 eggs to the tracheal walls, where the larvae hatch and develop in 11–15 days to adult mites.[2] The mites parasitize young bees up to two weeks old through the tracheal tube openings. There they pierce the tracheal tube walls with their mouthparts and feed on the haemolymph of the bees. More than a hundred mites can populate the tracheae and weaken the bees. The mites are generally less than 175 micrometres (0.007 in) long, and can only be seen and identified under a microscope.[2]

Other mites that are similar in appearance are Acarapis externus, and Acarapis dorsalis.
