Lacewings: All You Need to Know for a Thriving Garden

Lacewings are beneficial insects that play a crucial role in maintaining a healthy garden. They are available in two varieties, green and brown, with green lacewings being the most common. These delicate creatures help keep the population of pests, such as aphids, under control.

The lacewing life cycle has four stages: egg, larva, pupa, and adult. Overwintering occurs either as a pupa or adult, depending on the species. These insects are also often commercially available, making them easy to introduce into your garden.

Green Lacewings

Green lacewings are a common type of lacewing with a transparent, delicate body and long, slender antennae. They are known for their role as beneficial insects in gardens due to their predaceous larval stage1. Some characteristics of green lacewings include:

  • Bright green color
  • Small heads
  • Wings with a delicate, net-like pattern
  • Presence of numerous species across genera2

An example of a green lacewing species is Chrysoperla carnea.

Brown Lacewings

While green lacewings are more prevalent, brown lacewings also play an essential role in biological control. Brown lacewings not only have predaceous larvae, but the adults also feed on aphids3. Some features of brown lacewings include:

  • Brownish color
  • Similar build to green lacewings but generally smaller
  • Less common than green lacewings

An example of a brown lacewing species is Micromus tasmaniae.
