Notiobiellinae

Distinguished from other Hemerobiidae subfamilies by wing venation characters including the arrangement of radial and medial sectors, and by male genitalic structures. Notiobiellinae typically have a more complete set of crossveins in the radial sector compared to Hemerobiinae. Identification to genus level requires examination of wing venation details and genitalia; Notiobiella and Zygobiella are separated by differences in the male paramere structure and female subgenital plate morphology.

Adults are small to medium-sized lacewings with brownish or tan coloration. Wings are typically hyaline with brownish markings and possess distinct venation patterns including numerous crossveins and forked costal veinlets. Body form is generally slender with long, filiform antennae. Larvae are elongate, somewhat flattened, with prominent sickle-shaped mandibles adapted for predation.

Found in diverse terrestrial habitats including forests, woodlands, shrublands, and occasionally disturbed areas. Adults and larvae occupy vegetation where prey populations occur, including tree bark, leaf surfaces, and ground litter. Specific microhabitat associations vary by genus and species.

Widely distributed across multiple continents including North America, South America, Europe, Africa, Asia, and Australia. The subfamily shows greatest diversity in tropical and subtropical regions, with some genera having more restricted geographic ranges.

Adult activity patterns vary by species and geographic location. In temperate regions, adults are most commonly observed during spring and summer months. In tropical regions, activity may occur year-round with peaks corresponding to favorable moisture and prey availability conditions.

Larvae and adults are predatory, feeding on small soft-bodied arthropods including aphids, scale insects, mites, and other small insects. Specific prey preferences vary among species but generally align with available prey in occupied microhabitats.

Development includes egg, larva, pupa, and adult stages. Eggs are laid on vegetation or other substrates. Larvae are active predators, passing through three instars before spinning silken cocoons for pupation. Adults emerge from cocoons and may feed on prey, honeydew, or other liquid food sources in addition to small arthropods.

Adults are generally nocturnal or crepuscular, often attracted to light. Larvae are solitary, active hunters that move through vegetation or across substrates in search of prey. Both life stages are capable of rapid movement when disturbed. Some species may exhibit seasonal migration or dispersal patterns in response to prey availability.

Functions as a generalist predator of small arthropod pests in terrestrial ecosystems. Contributes to natural biological control of potential agricultural and forest pests including aphids, scale insects, and mites. Serves as prey for larger arthropods, birds, and other insectivores.

Of interest in biological control research due to predatory habits, though less commercially utilized than some other lacewing groups. Occasionally documented in agricultural and horticultural settings where they contribute to pest suppression. Not considered medically or economically significant as pests.

• HemerobiinaeOther subfamily within Hemerobiidae; distinguished by wing venation patterns, particularly the reduced number of crossveins in the radial sector and differences in male genitalic structures.
• DrepanacrinaeAnother Hemerobiidae subfamily; separated by forewing venation with fewer branches in the radial sector and distinctive shape of the pseudomedia.
