Leucochrysa callota
Banks, 1915
Leucochrysa callota is a of green lacewing in the Chrysopidae, order Neuroptera. It was described by Banks in 1915 and is currently classified within the subgenus Nodita. The species is recorded from both Middle America and North America. Members of the Leucochrysa are known for their distinctive trash-carrying larval , where larvae cover themselves with debris for camouflage and defense.

Identification
of Leucochrysa callota can be distinguished from other green lacewings by the combination of: body coloration and markings on the and ; wing venation patterns characteristic of the ; and genitalic structures. The subgenus Nodita, to which this belongs, is distinguished from other Leucochrysa subgenera by specific features of the male and female genitalia. Accurate identification to species level typically requires examination of genitalic characters under magnification.
Distribution
Middle America and North America. Specific country records and precise range boundaries have not been comprehensively documented in the available literature.
Life Cycle
As with other chrysopids, Leucochrysa callota undergoes complete with , larval, pupal, and stages. Larvae of Leucochrysa are known for their distinctive trash-carrying , covering themselves with plant debris, prey remains, and other materials held by specialized hooked setae. This behavior serves as camouflage and physical protection. The specific duration and voltinism for L. callota have not been documented.
Behavior
Larvae exhibit trash-carrying , a characteristic trait of the Leucochrysa. This involves collecting and carrying debris on the surface of the body using specialized hooked setae, forming a protective covering that provides camouflage and physical defense against .
Ecological Role
As with other green lacewings, and larvae are predatory, contributing to of pest insects. Larvae are of small arthropods including aphids, mites, and other soft-bodied insects.

Taxonomic placement
The has been placed in the subgenus Nodita within Leucochrysa. The subgenus Nodita was established based on distinctive genitalic characters and larval . Some sources list the species as Leucochrysa (Nodita) callota.
Larval defensive behavior
The trash-carrying of Leucochrysa larvae is among the most specialized in the Chrysopidae. The debris covering can include lichen fragments, bark pieces, dead insects, and other materials, making larvae extremely cryptic in their natural environment. When disturbed, larvae may also coil into a defensive ball posture, as documented in the related Leucochrysa pavida.
