Numbers
7 spp. in our area are known to have naked or non-debris-carrying larvae (6 for the entire genus)
1. Chrysoperla (all species)
2. Chrysopa (at the exclusion of C. slossonae)
3. Meleoma (all naked or nearly so)
4. Nacarina (single species)
5. Nineta (all species)
6. Pimachrysa (single species reared: P. fusca)
7. Plesiochrysa (single species)
Identification
Green lacewing larvae have tubercles with protruding setae (or hairs). Species that don't carry a debris packet have a longer, more slender abdomen, generally unhooked setae, and no long scoli (the spines associated with holding a debris packet).(1) So far, the following naked green lacewing larvae on BugGuide have been identified past family:

Chrysopa sp.
Chrysoperla carnea-group
Chrysoperla comanche
Chrysoperla externa
Chrysoperla rufilabris
Meleoma sp.
Life Cycle
See Green Lacewings for general information on this family.
See Also
Debris-carrying green lacewing larvae have a shorter, broader abdomen, hooked setae, and long scoli.
Kymachrysa intacta
Leucochrysa sp.
Leucochrysa insularis
Leucochrysa pavida

Brown lacewing larvae lack tubercles with setae and have proportionally more slender, elongate bodies than any of the green lacewing larvae. They also have shorter mandibles.
Hemerobius sp.
Micromus sp.
