A most bizarre and mysterious cocoon

it looks like a little hut/house surrounded by a tall fence. What a fantastic thing!

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

I'm guessing that it evolved the fence to prevent crawling predators from feasting on the cocoon while the bug is pupating. That said, its a really interesting example.

The next time the guy is out in the jungle and sees one the thing to do is to take it home, put it in a jar, and wait to see what pops out. I learned about mosquito eggs that way, as a youth I thought they were tadpole eggs, put them in my jar and waited for frogs. Instead I got mosquito larvae and then a jar of dead mosquitos (I didn't take the top off once I recognized the larval form.)

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 other pages talkng about it.

This feels sub-optimal.

What's a better approach?
