Spider mite destroyer

Stethorus punctum (Leconte)
Coleoptera: Coccinellidae

Adults are oval, convex, uniformly shiny black, and covered with sparse, fine yellowish to white hairs (A). The larva is gray to blackish and has many long-branched hairs and black patches (B). As the larva matures, it becomes reddish, at first on the edges of the body, and eventually entirely just prior to pupation (C).

Note: This species is sensitive to most broad-spectrum insecticides.


The larvae and adults are important predators of mites. Normally not found in tree fruits north of PA.

Note: Both forms can consume as much as 100 motile forms per day.
