This record describes Kymachrysa intacta (species). Recorded family: Chrysopidae. Recorded order: Neuroptera.

Identification and Appearance

Kymachrysa intacta - Kymachrysa intacta
Contributed by Jonathan Hoskins; Additional contributions by v belov

Kymachrysa is one of several genera with a pale streak down the body and is distinguished by its sinuate longitudinal veins, between the inner and outer gradate veins. In most other green lacewing genera, the longitudinal veins are essentially straight. K. intacta has reddish markings in contrast to the black markings of K. plactita .

Habitat and Range

Habitat

Eggs are laid on the trunks of deciduous or evergreen trees, and the debris-carrying larvae form their debris packet from the woody material of these trees.

Geographic Range

widespread (Canada: ON, QC; United States: AZ, CA, CO, MN, MO, NC, NH, NM, NV, NY, OR, TN, TX, UT, WI, WV, WY)

Seasonal Activity

Adults: June - mid-October, most prominent in August

Diet and Behavior

Life History

Eggs hatch into the first instar larvae around September to October. Development is influenced by the length of daylight. They overwinter as second instar larvae until about March to April. They pupate and then emerge as adults in June, with adult activity peaking in August. Adults lay eggs on the trunks of deciduous or evergreen trees from July into late September to early October, and adults die around mid-October.

About Antlions, Lacewings, and Allies: the wider group

Order-level background for Neuroptera, the group containing Kymachrysa intacta. Species-specific details appear above.

Group overview

Neuroptera (lacewings, antlions, owlflies) includes ~6,000 described species. Green lacewing larvae are called 'aphid lions' - a single larva can consume up to 200 aphids per week.

Ecological role of the group

Antlion larvae build conical pit traps in sandy soil - an engineering feat studied by physicists for insights into granular mechanics. Adult lacewings are important pollinators of night-blooming flowers.

Economic and practical significance of the group

Lacewings are commercially reared and sold as biological pest control agents. The global biological pest control market, which heavily features lacewings, was valued at $6.6 billion in 2023 and is projected to reach $16.4 billion by 2033.
