The Green lacewing larvae is the most beneficial stage with the lacewings. They feed on soft-bodied insects like aphids, but will also feed on caterpillars and some beetles. The biggest benefit of lacewing larvae is how aggressive they are. They will eat anything they can catch, and they are always hungry. They’re also cost effective, especially the eggs. They have the ability to quickly knock down moderate levels of aphid infestations, as well as help control many other pests.
Green Lacewing eggs are oval and pale green. Just before the larvae hatch, eggs turn gray. The eggs are shipped in vials with food and a carrier such as rice hulls, bran or vermiculite.
There are 3 species of mixed predatory fly parasites in your order: Spalangia cameroni, Muscidifurax zaraptor and Muscidifurax raptorellus. Fly parasites search fly-breeding areas for fly pupae containing developing flies. Once inside, the eggs hatch inside the fly pupa and feed on the developing fly and after two to three weeks of feeding, an adult fly parasite emerges to repeat the cycle. Each female fly parasite can kill approximately 100 immature flies in her lifetime.
The praying mantis is an ambush hunter: it sits very still, blending in with its surroundings and waiting patiently for an unwary insect to come near. Then it easily snatches its unsuspecting victim -- some much larger than itself. When it spots one, it takes the mantis only 50-70 milliseconds to strike out with its forelegs and snare its prey. The diet of the praying mantis includes all sorts of insects and spiders, and sometimes even frogs, lizards, or mice.
