Aphidius matricariae (parasitoid)
Aphid Parasite:  A small parasitic wasp that preys primarily upon the green peach aphid and as many as 40 other related species. This native North American parasite occurs naturally outdoors and frequently parasitizes aphids in green houses.

Aphidoletes aphidoma (midge larva)
Aphid Predator:  The larval stage of this predatory gnat-sized insect preys on all types of aphids, in indoor and outdoor settings. Larvae grow up to 1/8 inch long and can consume aphids much larger than themselves and may kill 4-65 aphids per day.

Hippodamia convergens (predator)
Lady beetle / Ladybug:  The most common of all beneficial insects, these voracious predators feed on aphids, adelgids, chinch bugs, asparagus beetle larvae, thrips, alfalfa weevils, bean thrips, grape root worms, Colorado potato beetle larvae, whitefly, and mites and many other soft-bodied insects and eggs.

Coleomegilla maculata (predator)
Lady beetle: Very common predator preys on mites, insect eggs and small larvae. Prey include pea, green peach, cabbage, and potato aphids and greenbug; eggs of European corn borer, cabbageworm, fall webworm, and corn earworm; asparagus beetle, Mexican bean beetle, and Colorado potato beetle eggs and larvae.

Leptomastix dactylopii (parasitoid)
Citrus mealybug parasite:  A tiny parasitic wasp feeds and chews on citrus mealybug both indoors and outdoors. Often used in conjunction with mealybug destroyer.
