Another interesting cocoon, linked to from the comments: http://blog.perunature.com/2013/06/the-incredible-urodid-mot...

Instead of hiding, the caterpillar builds an open-air net-like structure which hangs by a thread from the bottom of a leaf. The video hypothesizes that the structure both protects the pupa from ants and allows rain to flow through it (both of which seem like critical features in the Amazonian rainforest).

Also, it looks really cool.

Any search engine experts here? How do people try to find the answer to this question if they know nothing about the subject? My approach is to bang in various words and do image searches, forcing some and not others, and then try similar words. [weird cocoon] or [weird egg sac peru] and then sometimes including a subject word. (Entomology). Then I do a TinEye search, or a GoogleImage search to see if I can find othe…

I'm not sure if you have much of a chance of finding the answer if you know nothing about the subject - unless someone else already blogged about it somewhere. I'm sure that many of the people that are confused about it in the comments actually do have a background in biology, and they're having a tough time.

There's another possibility. Because of where this was discovered, it's more than possible that it's a new species. There are plenty of undiscovered species in the tropics, especially in the insecta class.

A few months ago a friend told me he felt hn had jumped the shark. This frontpage discussion about a blog post about a reddit thread pretty much settles any debate there was to be had on that topic!

"I'll miss the sea, but a person needs new experiences. They jar something deep inside, allowing him to grow. Without change something sleeps inside us, and seldom awakens. The sleeper must awaken."

A quick search turns up Bucculatricidae as a good candidate. Example cocoon: http://bugguide.net/images/raw/Y0BQZSBQF0AQJ08KLSBQTK5KCK4K9...

I thought the same, but they already discussed that in the comments [1] as the first serious contender, only to ultimately dismiss it as something else entirely.

Incredible. I looks the organism erected a fence to protect whatever it is in the center. If this turns out not to be a hoax it will be truly amazing. It is part of the " Endless Forms " of life.

It might not be the only bug that believes fences make good neighbors.

FYI: I found out about that from http://io9.com/we-have-absolutely-no-clue-what-built-this-cr...

They came to the same conclusion in the original thread last week - http://www.reddit.com/r/pics/comments/1lcb09/possible_new_sp...

Nature never ceases to amaze me. If you want to see some of the weirdest, most fantastically odd things Evolution has produced (for example, dancing spiders with multi-colored 'capes' that pop up), I highly recommend this blog: http://wtfevolution.tumblr.com

What a great site! Thanks.
