Malagasy Paper Wasp
A slender wasp with an olive-brown body, long dangling legs, and narrow waist. It builds small, exposed paper nests from chewed plant fibers on the underside of leaves and eaves.
Did You Know?
Females establish dominance hierarchies on the nest, with the queen maintaining her rank through aggressive posturing and antenna drumming.
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.
