#115845 Identification – Chrysopidae sp.

Identification confirmed. Empty cocoon. Suggest that an editor start a new "No Taxon Cocoons" category under Chrysopidae for images such as this. This would help remove clutter from the chrysopid unknown area. It is unlikely that such cocoons will ever be identified beyond family (unless there are shots from reared specimens...), but I think that it would be good to retain them (as has been done for eggs, larvae, and debris-carrying larvae).

Green lacewing cocoon

Here is a description of the cocoons of hemerobiidae from this website:

"The cocoon is loosely woven, double-walled, elliptical in outline, and generally is formed in protected spots, such as under bark, rather than exposed on bark or foliage. Cocoons differ markedly from the nearly spherical parchment-like ones of Chrysopidae."

Are you aware of other families that could have made this? As far as I know, it is safe to say this is a chrysopid cocoon.

I don't have any experience with lacewing cocoons. I just moved based on Eric's comment, which seemed to indicate uncertainty.

Hatched lacewing cocoon!

Nice shot of the empty cocoon of a lacewing (order Neuroptera, either Chrysopidae or Hemorobiidae).
