Summary

Dusty-wing lacewings (Coniopterygidae) are small net-winged insects easily recognized by their unique dust-like appearance on wings. They have a significant ecological role as predators of pest insects and are predominantly associated with woody habitats. Their delicate morphology requires specific methodologies for accurate identification.

Physical Characteristics

Body length 2.5-5 mm; wingspan between 1.8 and 5 mm; translucent brownish wings covered with waxy scales appearing dusty; adults carry wings nearly side-by-side when at rest.

Identification Tips

Genus-level identification requires examination of wing venation of both fore- and hind wings; species distinction typically requires microscopic examination of genitals.

Habitat

Predominantly arboreal, associated with woody plants like shrubs and trees.

Distribution

Worldwide and throughout North America.

Diet

Adults and larvae feed on aphids, mealybugs, spider mites, scale insects, whiteflies, and other soft-bodied arthropods; adults may also consume honeydew and scale secretions.

Life Cycle

Usually two generations per year; individuals overwinter as larvae, adults are crepuscular.

Reproduction

Females lay single eggs on bark or leaves.

Ecosystem Role

May play an economically important role as predators of homopteran pests.

Economic Impact

Could be economically significant as biological control agents against pest insects such as aphids and whiteflies.

Collecting Methods

Hand lens examination for identification; microscopic examination for species distinction.

Preservation Methods

Standard entomological techniques for specimen preservation.

Evolution

Formerly believed to be monotypic within the superfamily Coniopterygoidea, evolution suggests they may share close relatives with spongillaflies (Sisyridae) based on larval morphology.

Misconceptions

Often mistaken for whiteflies due to their size and appearance; true classification places them in a distinct order (Neuroptera).
