Spring has a sound. Birdsong. Rain on new leaves. The first lawn mower of the season. And if you listen very closely, near the garden at dusk?
A delicate, papery flutter.
That’s the green lacewing. And it’s been waiting all winter to meet you!
What Is a Green Lacewing?
Green lacewings (family Chrysopidae) are slender, elegant insects found across North America, Europe, and beyond. They’re soft, pale green, about the size of a paperclip, with enormous, intricately veined wings that catch the light like tiny stained glass windows. They look fragile. They’re not.
The Adults
Adult green lacewings are mostly harmless, gentle little creatures. They flutter around at dusk and nighttime, feeding on nectar, pollen, and honeydew from aphids. They’re pollinators, peaceful, and oh so lovely to look at. But their children? Their children are complete monsters.
The Larvae
Green lacewing larvae are called aphid lions.
That should tell you everything you need to know. They’re small, brownish, alligator-shaped predators with enormous curved mandibles. They grab aphids, mites, whiteflies, thrips, and small caterpillars, inject them with digestive fluid, and suck them dry.
One larva can consume up to 200 aphids per week. Per week. They’re one of the most ferocious predators in your garden. Seriously. They’re also smaller than your pinky nail…but size is not the point.
The Eggs
Green lacewing eggs are one of nature’s quiet wonders.The female lays each egg at the end of a long, thin silken stalk, attached to a leaf. A cluster of them looks like a tiny, surrealist art installation. Like something you’d find in a gallery with a very long, confusing title. The stalks keep the eggs elevated and isolated, making it harder for predators and cannibalistic siblings to reach them. Practical. Elegant. Slightly eerie. Classic lacewing.
Where to Spot Them
• Gardens, meadows, and woodland edges
• Near aphid-heavy plants like roses, milkweed, and vegetables
• Around porch lights and windows at night (they’re attracted to light)
• Look for those distinctive stalked eggs on the undersides of leaves in spring and summer
Why They’re Cool
• They’re one of the most effective natural pest controllers available, AND you can actually buy lacewing eggs to release in your garden.
• Some lacewing larvae camouflage themselves by stacking the dried husks of their victims on their backs. A coat made of the remains of their enemies. Horrifying. But brilliant.
• Adults are completely harmless and will not bite or sting.
• Their wings are so intricately veined that entomologists use the patterns to identify species.
• They have been used in organic farming as biological pest control for decades.
