Living With Lacewings

Lacewing

Lacewing

Lacewings are predators of aphids and other small insects in the both the adult and larval stage. Adult lacewings supplement their insect diet with honeydew nectar and pollen. The common green lacewing can be beneficial in agro-ecosystems as biocontrol agents to suppress aphid populations. The ability to use resources other than aphids for food allows larger lacewing populations to be supported when aphids are less abundant. Lacewings can be better for suppressing an aphid population at a low level than predators that cannot be sustained at low aphid populations.

The lacewing pictured left rests with its body parallel to the stem of a plant.  Its wings are a translucent green that blends into the background making a resting lacewing difficult for predators to see.
