    Here's some Info from Phil:

    This type of cocoon is known as a "open-network cocoon" and is unlike other cocoons in that it doesn't completely enclose the pupa in silk. Instead, it only partially surrounds it, likely enabling better airflow to control for humidity and may help prevent fungi from growing on, and eventually killing, the pupa. This cocoon very likely belongs to a moth in the family Urodidae, which is known for making this type of lattice-structured cocoon surrounding its pupa.

    Instead of saving for my kids' college, I make videos using the money I would have saved.
    The thought is it will help educate the world as a whole, and one day generate enough revenue to pay for their education. Until then if you appreciate what you've learned in this video and the effort that went in to it, please SHARE THE VIDEO!

                                  You look like a 9 year old who saw a crysalis for the first time, stopped aging, then spent the next 25 years of your life playing with caterpillars/butterflies.

Was really cool when it used to happen , everything Orange and black. I got bats and Turkey vultures now. All cocoons I've ever seen were solid, these are really cool.

Shame on him! There are papers referenced on wikipedia that talk about these moths dated back to 1963, so it wasn't discovered for the first time after then, at least.

                                                                      Edit: that show eluded that the person discovered it, but they never actually say that. So, false alarm. Sorry.
