The broad mite, Polyphagotarsonemus latus, is a microscopic species of mite found on many species of plants, including important agricultural species such as grapes, apples, and other fruits. Broad mites are also currently affecting cannabis plants, as the industry matures with legalization. The mites are found in many areas throughout the world and are major pests in greenhouses.
Adults: Female mites are about 0.2 mm long and oval in outline. Their bodies are swollen in profile and a light yellow to amber or green in color with an indistinct, light, median stripe that forks near the back end of the body. Males are similar in color but lack the stripe. The two hind legs of the adult females are reduced to whip-like appendages. The male is smaller (0.11mm) and faster moving than the female. The male's enlarged hind legs are used to pick up the female nymph and place her at right angles to the male's body for later mating
