Metaphycus Scale Parasitoid

A golden-yellow parasitoid wasp that attacks black scale and other soft scale insects on citrus and olive trees. It is one of the most widely used encyrtids in commercial biological control.

💡

Did You Know?

Adults also feed directly on young scale insects by piercing them with their ovipositor, killing hosts through both parasitism and host-feeding.

Rough Stink Bug

A gray-brown bark-colored stink bug with a rough, granular body surface that provides excellent camouflage on tree trunks. It has four small pale spots on the scutellum. It feeds on tree fruits but also preys on caterpillars.

💡

Did You Know?

Its bark-like coloration and texture make it virtually invisible when resting on tree trunks, and it will press itself flat against the bark and freeze when disturbed.
