If you think you have an infestation of lacewing, look closer! Lacewings make lunch of those harmful bugs that munch on your landscape plants, such as “aphids… mites… caterpillars, leafhoppers, mealybugs and whiteflies.”
So, if you see them, know that they are not harmful to your plants, but are there to feed on something that is!
