Parasited Cocoon

Juan, I may have misunderstood your description entry.
These stalked eggs are always fascinating, especially on an unlikely substrate as this cocoon shell.

You are right Martin, this is a parasited Cocoon but it wasn´t parasited by the Chrysopids (I never said that), they are only using the cocoon shell as a substrate

The eggs are indeed typical of lacewings. Lacewing (Chrysopa) larvae (or antlions) http://www.flickr.com/photos/puckyireth/... are carnivorous and I expect they will eat only small things they can catch, such as aphids. I would guess these eggs were placed on the cocoon because it was alive (cool) and there was no plant found nearby.

This must be a rare sighting. Thanks for sharing.
