Dusty lacewings
The Coniopterygidae family, commonly known as dusty lacewings, belongs to the order Neuroptera. These are among the smallest members of the lacewing group, typically measuring between 2 and 5 mm in length. Their characteristic dusty appearance is due to a waxy secretion produced by specialized glands on their bodies.

Dusty lacewings
From an agronomic perspective, dusty lacewings are not pests; they are highly beneficial predatory insects. They play a significant role in integrated pest management by consuming a variety of soft-bodied insects and mites that damage ornamental plants, fruit trees, and various agricultural crops.
The primary food sources for both larval and adult stages of dusty lacewings include aphids, scale insects, whiteflies, and spider mites. Their predation efficiency makes them valuable allies for farmers and gardeners who aim to maintain ecological balance without heavy reliance on synthetic pesticides.
The life cycle follows a complete metamorphosis consisting of egg, larva, pupa, and adult stages. The larvae are active hunters, often found wandering on leaves or branches in search of prey. Before pupation, the larvae spin a distinct double-layered silk cocoon, which is usually attached to bark or the underside of leaves.
- Avoid broad-spectrum insecticide applications to protect populations.
- Maintain diverse vegetation to provide refuge for overwintering stages.
- Encourage natural habitats like hedgerows near crop fields.
Conservation of dusty lacewings is a key strategy in organic and sustainable farming. By minimizing chemical usage, growers allow these natural predators to effectively regulate pest populations, reducing the need for costly and environmentally harmful chemical interventions in the long run.
