Spider mite
Description
Any of several small plant-feeding mites of the family Tetranychidae (subclass Acari). Spider mites obtained their name because they spin fine webs over the infested plant. They feed on house and garden plants, and can be a major problem in conservatories and orchards. The mites winter in cracks, crevices, mulch, and trash. Their development from egg to adult is 2 - 3 weeks. The adult insects are 0.5 - 0.7 mm long. While most mites are red, they can also be brown, yellow, orange, or green. The spider mite has become resistant to many pesticides; the current treatment is often the introduction of a predatory mite Phytoseiulus simili.
