At this time of year you may see adult lacewings hovering around your roses. These green or brownish insects with characteristic, lacy wings look so delicate and yet they’re voracious aphid eaters. The adult females flutter around, looking for aphids so they can lay their eggs nearby. Each egg is laid on a slender stalk so it’s out of the reach of ants and other insects, and when the larvae hatches out the maggot wanders around stems and leaves gorging on aphids. Some species cover themselves with the dry husks of their prey, presumably as camouflage rather than as trophies! Adults are on the wing until late summer and most often seen on warm, still evenings.
How to help them A bug hotel will give the adults a safe winter home but so too will evergreen shrubs, which are favourite winter quarters. Avoid the use of pesticides to avoid killing the lacewings and their food.
Install a bug hotel and watch it fill up with guests!
