Debris-Carrying Larva eating Sawfly eggs - Ceraeochrysa lineaticornis

Debris-Carrying Larva eating Sawfly eggs - Ceraeochrysa lineaticornis
Atco, Camden County, New Jersey, USA
September 21, 2014
Not great image... Found eating Sawfly (Caliroa) eggs on black oak leaf.
I found Caliroa eggs on that leaf 2 days ago and was looking for hatching... :(
Looks like this larva's favorite debris is exuvia. I see spider and leafhopper exuvia...

Moved from Unidentified Debris-Carrying Larvae.

Exuviae look more incidental to me. Scolus length, range, and facial markings should narrow this quite well to Ceraeochrysa, of which only C. lineatcornis occurs this north. Facial markings are also appropriate for that species.


For other debris-carrying genera in range:
Apertochrysa only has 1 eastern species (A. macleodi), which is quite rare to the point that I wouldn't expect its larva to be photographed.
Chrysopa only has 2 debris-carriers in this range (C. quadripunctata & C. slossonae), and they would have very short scoli.
• Eremochrysa only has 1 eastern species (E. canadensis). It's quite rare and unlikely for its larva to be photographed.
• Kymachrysa only has 1 eastern species (K. intacta), which has different head markings.
• Leucochrysa is the only other genus with a common species (L. pavida, but it has very different head markings and debris packet, plus longer scoli.
