Hello again! How’s your crop? I hope it’s doing well and you’re not dealing with any major pest issues. If you are however, have you considered including beneficial organisms to your pest management program? Well that’s what we’re talking about today, specifically the insects commonly called “lacewings.” These little helpers are great for battling aphids and spider mites organically. Read on!


Quick Look:

  1. Scientific Name: Over 1300 species of the family Chrysopidae
  2. Common Name: Lacewings (lacewing larvae are also referred to as “aphid lions” or “aphid wolves”).
  3. How They Help: Larval lacewings prey on aphids and spider mites. Adults also prey on these to a lesser extent.

Lacewings get their name from their delicately-veined wings. Beautiful, don’t you think?


More on Lacewings


Most lacewing species used as pest control are classified in one of two genera: Chrysopa and Chrysoperla. These insects are common in North America and Europe and may be a natural part of your operation already. However, you can purchase lacewings yourself and boost their numbers.

While adult lacewings will supplement their diet of pollen and nectar with aphids and spider mites, larval lacewings are the real predators. Sometimes referred to as aphid lions or aphid wolves, these larvae hatch and immediately molt before climbing the nearest plant to begin hunting for pests. In addition to the spider mites and aphids, these larvae will eat any soft-bodied arthropod they can sink their mouthparts into.

Writers Note: Larval lacewings have been known to bite fingers, so be careful!

Larval lacewings aren’t as pretty as their parents, but they’re much more dangerous.


Consider yourself lacewing literate! Beneficial organisms are a great addition to your pest control regimen, especially when we’re talking about Cannabis, a consumable crop that many patients depend on for relief. The last thing a sick person needs is to inhale chemical pesticides.
