10 spp. in our area are known to have debris-carrying members (9 for the entire genus)
1. Abachrysa (single species)
2. Ceraeochrysa (all species)
uses wool from the wooly alder aphid; C.quadripunctata
are only occasional debris-carriers)(1)
4. Chrysopodes (single species)
5. Eremochrysa (all species)
6. Kymachrysa (all species)
7. Leucochrysa (all species)
8. Nothochrysa (single species)
9. Pseudomallada (all species)
10. Yumachrysa (all species)
Green lacewing larvae have tubercles with protruding setae (or hairs). Species that carry a debris packet have a shorter, broader abdomen, hooked setae, and long, scoli (the spines associated with holding a debris packet).(2)
So far, only a few images of debris-carrying green lacewing larvae on BugGuide have been identified past family:
See Green Lacewings
for general information on this family.
It seems that the trash carried by the larvae of several species confers some protection against predatory lady beetles.
Naked green lacewing larvae
have a longer, narrower abdomen, unhooked setae, and no long scoli.
Brown lacewing larvae
lack tubercles with setae and have proportionally more slender, elongate bodies than any of the green lacewing larvae. Brown lacewings are naked larvae and thus lack any sort of scoli. They also have shorter mandibles.
