Ceraeochrysa
trash-carrier lacewings, green lacewings
Ceraeochrysa is a genus of green lacewings in the family Chrysopidae, established by Adams in 1982 based on distinct genitalia structure. It is the second largest genus in Chrysopidae with 61 species distributed from southeastern Canada to Argentina, with highest diversity in the Neotropics. Larvae are known as 'trash carriers' that construct dorsal packets of debris for camouflage, including insect wax, lichen, and plant material. The genus contains important biological control agents that prey on mealybugs, aphids, mites, thrips, and lepidopteran eggs.
Ceraeochrysa cincta
Ceraeochrysa cincta is a green lacewing species in the family Chrysopidae, distributed across the Americas from North America through the Caribbean to South America. Laboratory studies demonstrate its potential as a biological control agent, with larvae showing instar-specific predatory preferences on prey eggs. Populations in southeast Brazilian agroecosystems exhibit high genetic diversity with broad gene flow across different crop systems. The species produces non-pedunculated infertile eggs in later generations under laboratory conditions, a trait relevant to mass rearing programs.
Ceraeochrysa claveri
trash bug (larval stage)
A green lacewing in the family Chrysopidae, Ceraeochrysa claveri is a polyphagous predator with established value in biological control of agricultural pests. Larvae are "trash carriers" that construct dorsal camouflage packets using assorted materials including lichen, plant trichomes, and notably the wax of mealybugs and other insects. The species has been documented incorporating live mealybug nymphs into these packets, representing the first recorded instance of active placement of live prey onto the larval packet. Adults feed on pollen and may contribute to pollination. The species shows high genetic diversity across agroecosystems and is compatible with certain biopesticides including Bacillus thuringiensis serovar aizawai.
