Chrysoperla comanche

Identification to species within the Chrysoperla carnea-group requires specialized techniques, as morphological differences are minimal. Historically, species in this group were considered a single holarctic species. Accurate identification of C. comanche relies on vibrational song analysis (duetting behavior between sexes), specific morphological features, and DNA analysis. Adults are green lacewings with golden eyes, typical of the genus. Differentiation from C. carnea and C. rufilabris in field settings may require expert examination or behavioral cues such as winter activity and habitat preference.

California San Joaquin Valley vineyards; agricultural habitats including grape vines, prune trees, and ground covers. Natural habitats in northern Mexico and southern USA include nopal (prickly-pear cactus, Opuntia ficus-indica) and white poplar (Populus alba) trees. Also recorded in shortgrass prairie and arid regions. Adults have been observed in outdoor winter conditions at ambient temperatures without entering diapause.

Native to northern Mexico and southern USA. Recorded from Canada, USA, Mexico, Chile, and Hawaii. Specific localities include Fresno County, California; State of Mexico; and Kearney Agricultural Research and Extension Center (KREC) vineyards. GBIF records indicate presence in North America and Oceania.

Adults active year-round in California's San Joaquin Valley, with continuous egg deposition observed from October through January. Eggs deposited in November hatched after 49–53 days at average 7.8°C. Development from egg to adult occurs from 16.7 days at 32.2°C to 56.1 days at 15.6°C; no development at 12.7°C or 36.7°C.

Generalist predator of soft-bodied arthropods. Larvae consume late instar leafhoppers (Erasmoneura variabilis), with approximately 250 individuals consumed during development at 26.7°C. Documented prey includes aphids (Melanaphis sorghi, M. sacchari, Chaitophorus populialbae), psyllids (Diaphorina citri), whiteflies (Bemisia tabaci), thrips (Frankliniella occidentalis), and cochineal insects (Dactylopius opuntiae). Laboratory rearing successful on Mediterranean flour moth (Ephestia kuehniella) eggs. Adults fed artificial diet of whey yeast, enzymatic protein hydrolysate of Brewer's yeast, honey, and water.

• Ephestia kuehniella - laboratory food sourceMediterranean flour moth eggs used for rearing
• Opuntia ficus-indica - habitat/associated plantnopal cactus, host of cochineal insect prey
• Populus alba - habitat/associated plantwhite poplar, host of aphid prey
• Vitis spp. - habitatgrape vines, primary agricultural habitat
• Metschnikowia chrysoperlae - symbiontyeast isolated from digestive tract and eggs, possible vertical transmission
• Candida picachoensis - symbiontyeast isolated from digestive tract
• Candida pimensis - symbiontyeast isolated from digestive tract

Egg stage: threshold temperature 10.6°C, 73.5 degree days. First instar: threshold 12.9°C, 38.5 DD. Second instar: threshold 11.5°C, 37.4 DD. Third instar: threshold 10.3°C, 44.3 DD. Pupal stage: threshold 11.0°C, 140.4 DD. Complete development (egg to adult eclosion) viable at 15.6–35°C. Larval period approximately 9.6 days at 26.7°C. Adults do not appear to enter diapause in California conditions; remain green and continue reproduction through winter. Average adult longevity 53.6 days. Mean lifetime fecundity 1087–1108 eggs, with 77.3–80.9% produced in first 30 days of reproduction. Peak egg production at approximately 10 days post-emergence.

Adults exhibit non-diapausing behavior in California's San Joaquin Valley, remaining green and continuing egg deposition through winter months (October–January) when other species become brown and enter diapause. Preference for grape vine habitat over ground covers compared to other lacewing species. Larval predation heavily weighted toward third instar consumption. Females likely search for oviposition sites at base of host plants. Duetting vibrational songs used for species recognition and mate location, with both sexes participating. Populations in field settings often small.

Generalist predator in agricultural and natural ecosystems, particularly effective in vineyard pest management. Candidate for augmentative biological control programs due to habitat preference for grape vines and non-diapausing behavior extending predatory activity into winter. More suitable than C. carnea and C. rufilabris for certain regions based on climatic adaptation and habitat specificity. Potential for commercial insectary production targeting specialty natural enemy market.

Evaluated for commercial insectary production and augmentative biological control release. Most commonly encountered lacewing species in post-release surveys in California vineyards, suggesting establishment success. Laboratory rearing protocols developed for potential mass production. Used in conservation biological control programs in Chile and other regions. Potential value in hot, arid agricultural regions where non-diapausing populations provide year-round pest suppression.

• Chrysoperla carneaHistorically confused due to morphological similarity within the C. carnea-group; distinguished by song, habitat preference, and non-diapausing winter behavior
• Chrysoperla rufilabrisSimilar habitat and prey associations; C. comanche distinguished by preference for grape vines over ground covers and lack of winter diapause in California conditions

The species was historically lumped with other members of the Chrysoperla carnea-group as a single holarctic species. Early biological control programs may have used misidentified specimens. Color-based identification alone is insufficient for species-level determination within this group.
