Thanks. Are the debris carry
Thanks. Are the debris carrying larvae specific to species or genera. IE. do some species always carry debris and others always do not? Or may a species carry or not carry?

 
I don't know, unfortunately.
I would suspect the trait to be species specific, but I haven't seen any definitive information one way or the other.

 
Debris carrying
This is quite a bit after the question was asked, but yes, that assumption is correct. Certain genera (i.e. Chrysoperla and Chrysopa) are typically naked and without debris while others (i.e. Ceraeochrysa, Eremochrysa, Leucochrysa,…) most always carry debris. Though it seems there's an exception in Chrysopa slossonae (fairly cryptic with C. quadripunctata). Even the debris carried tends to be specific. So, for instance, Leucochrysa pavida is well-studied and known for its camouflage of lichens. Chrysopa slossonae often carries debris from wooly alder aphids ( Prociphilus tessellatus). Other debris-carriers are a bit less studied. At least one of the others carries dead ants.
