Stethorus punctillum

Stethorus punctillum predatory ladybug


The Spider Mite Destroyer (Stethorus punctillum) is a small black ladybug with small yellow antennae and measuring nearly 1.5 mm. The larva is dark in color. The eggs are oval and yellow in color. They are usually deposited near the colonies of pest mites.

Larvae and adults are predators and feed on all stages of several mite species such as two-spotted spider mite, spruce spider mite, southern red mite and European spider mite.

This little ladybug has demonstrated excellent ability to control pest mite infestations. It flies with a lot of ease and is able to detect outbreaks of infestations. Unlike Neoseiulus fallacis and Phytoseiulus persimilis, it can be used in crop with low humidity and high temperature.
