Introduction
Green lacewings, members of the Chrysopidae family, are delicate-looking yet fiercely predatory insects. Despite their fragile appearance, they are among the most effective natural enemies of aphids and other soft-bodied pests in gardens, orchards, and greenhouses.
Recognizing Green Lacewings
Adult green lacewings are about 1–2 cm long, with large, translucent wings that shimmer under light. They have slender green bodies and prominent golden or coppery eyes, which give them a fairy-like appearance. While adults feed on nectar and pollen, their larvae are the true pest killers.
Life Cycle
The life cycle includes:
- Eggs: Laid on long stalks to protect them from cannibalistic larvae
- Larvae: Known as “aphid lions,” these ferocious feeders resemble small alligators with sickle-like mandibles
- Pupae: Spin cocoons before transforming into adults
Each larva can consume up to 200 aphids or more during its development.
Diet and Prey
Lacewing larvae feed on:
- Aphids
- Whiteflies
- Mealybugs
- Spider mites
- Thrips
- Caterpillar eggs
This makes them ideal for integrated pest management (IPM) strategies.
Ecological Role
Green lacewings help:
- Reduce pesticide reliance
- Maintain ecological balance
- Enhance pollination indirectly by protecting flowering plants from pest damage
They’re a cornerstone species in sustainable agriculture and organic gardening.
How to Attract Lacewings
To support green lacewings in your landscape:
- Plant nectar-rich flowers (e.g., yarrow, dill, cosmos)
- Avoid chemical insecticides
- Provide evening light sources (lacewings are nocturnal flyers)
- Purchase and release commercial lacewing larvae for biological control
Conclusion
Green lacewings are nature’s silent warriors, devouring garden pests with relentless efficiency. Encouraging their presence is a step toward healthier, chemical-free growing environments.
