Green Lacewing Chrysoperla - 100 Adults
About Green Lacewings (Chrysoperla rufilabris)
The Green Lacewing is a nocturnal predator that aggressively and lethally consumes aphids and other soft bodied insects. The Green Lacewings life cycle is made up of three stages; eggs, larvae and adult stages. When the female Green Lacewing lays her eggs, they tend to pick an area with sufficient plants and leaves. The eggs are attached to a hair-like thread until the egg hatches. The larvae of the Green Lacewings are very ferocious in hunting down soft bodied insects. The larvae can grow up to 3/8th of an inch and they seize their prey and inject them with paralyzing venom. The Green Lacewing Adults feed on pollen and nectar however lay a lot of eggs. Adults are useful for the release onto trees, for as adults they have wings to fly. Green Lacewings also attack the eggs of pests. Green Lacewings will also attack most soft-bodied pests such as: Aphids, Thrips, Spider Mites, greenhouse whiteflies, mealy bugs, leafhoppers, and the eggs and caterpillars of most pest moths. Of all available commercial predators, this lacewing is the most ferocious and it adapts easily to go after pests of field crops, orchards, and greenhouses.
Each lacewing larva will devour 200 or more pests or pest eggs a week during their two to three week developmental period. After the larvae stage the Green Lacewing Larvae wraps itself in a cocoon silken thread. Approximately five days later adult Lacewings emerge to mate and repeat the life cycle. Depending on the weather conditions, the adult will live for roughly four to six weeks.
Green Lacewing Release Instructions
Once you have made it home with your Lacewings, you will determine which release guide to follow based on whether your package contained Lacewing eggs or Lacewing larvae. DO NOT STORE LACEWING LARVAE OR ADULTS; they must be used upon receiving your shipment! However, you CAN store Lacewing eggs for up to two weeks in a cool spot for future use but it is recommend to also be used immediately.
EGG RELEASE: Next, Gently disperse contents of the Lacewing eggs and rice hulls in fixed pouches supplied to you in your order. The pouches then should be distributed among your infested plants by stapling or paper clipping them to the leaves and/or placing them in the crotch of the plant.
LARVAE RELEASE: Release at sundown the day you receive the larvae. It is extremely difficult to see larvae with the naked eye! Tap out the larvae evenly onto infested plants. Try to spread them out as much as possible for they are cannibalistic and will feed on each other. To ensure you have them all out of the container, put the container itself in the foliage of your most heavily infested plants.
ADULT RELEASE: Release adults at sundown the day you receive the product. Please release closest to the plants that are infested. Open one or both ends of the tube and allow them to fly out freely and disperse on their own. If they are hesitant to fly out on their own, blow through the tube gently. Increase the egg laying activity of the adults by supplying them with a beneficial insect food (liquid form) or with flowering, pollen-producing plants near the release site.
Frequently Asked Green Lacewing Questions
Question:I hung my lacewing eggs outside to hatch and never saw any larvae emerge! What went wrong? Are they dead?
Answer:The small size of this insect in the developmental stages makes it very difficult to spot the larvae or eggs when they are released outside and instructions on the package specifically state not to try to look for the immature larvae as they camouflage into natural surroundings very easily.
Question:Do green lacewing adults also attack pest insects?
Answer:No, green lacewing adults only feed on pollen and nectar. The immature lacewings (larvae) are what feed on pest bugs.
Question:How can I tell if my lacewings have worked? What do I look for?
Answer:Since the larvae are too hard to see with the naked eye, customers usually instead monitor the size of the pest population to see if green lacewings have been an effective method of pest control. If there has been a noticeable decline in pest bugs, then the green lacewings are doing their job.
Question:How long does it take for lacewing eggs to hatch?
Answer:Lacewing eggs will require at least 5 days of consistent warm weather to hatch. Cooler temperatures will delay hatching.
