Garden Hero: The Green Lacewing, AKA Aphid Lions

July 28th, 2010

 

Did you know that green lacewing larvae are one of the most beneficial tools for keeping pesky garden villains under control? While the adult green lacewing is quite lovely, lacewing larvae appear somewhat menacing, with their large mandibles, pincher-like mouthparts, and armored looking bodies.

The green lacewing life cycle is pretty simple:

  1. An adult lacewing lays her eggs on plants, and each egg is attached to the tip of a hair-like filament.
  2. After just a few days, a predatory, and very hungry, larva emerges from the egg.
  3. After a short two- to three-week growing period, the larva spins a cocoon to pupate.
  4. An adult lacewing emerges approximately five days later, and it will then mate and repeat the life cycle. An adult green lacewing will live for approximately four to six weeks.

When a green lacewing larva emerges from its egg it’s ravenous, and it will feed on aphids, beetle larvae, leafhoppers, mealybugs, whiteflies, and more. When the larva grabs hold of its prey it injects it with paralyzing venom then sucks out the body fluids. Gross, yes, but the lacewing larva means business, and it will seek out prey rather than waiting for prey to come to it.

During the larva’s very short growing period it can consume up to 200 eggs, other larvae, and pests. To take advantage of their short life span, it is recommended that you release green lacewing larvae into your garden in early spring. If you want to help control your garden pests with lacewing larvae, release new larvae regularly in order to keep a steady supply in your garden and on your plants.

Adult green lacewings prefer to feed on honeydew, nectar and pollen. Light green in color, with large eyes and two long, thin antennae, the adult green lacewing also has long, transparent wings that have a distinct veins running through them.

 

Green lacewings prefer humid conditions, and plants that benefit from having the lacewing near include peppers, sweet corn, and tomatoes. If you want to control villainous garden pests organically, the green lacewing is a great choice for your garden!
