Cocoon with hair net - Climacia

Cocoon with hair net - Climacia
Deep Fork Wildlife Refuge, Okmulgee County, Oklahoma, USA

I would love to have seen this being made!

Moved from Spongeflies.

Climacia
After some digging, I've confirmed that this cocoon belongs to the genus Climacia; in the cocoon of the other North American genus, Sisyra, the fibers of the 'net' around the cocoon are simply crisscrossed rather than forming a delicate hexagonal mesh.

Thanks Hannah.

Spongilla fly!
I'm in the process of researching for a book I'm writing, Invertebrate Tracks & Sign, in which I hope to provide answers to as many of these sorts of mysteries as possible. I discovered your picture just a few days ago, and have been keeping it in mind as I peruse all the insect books I can get my hands on. I just now came across the following, from Frank E. Lutz's Field Book of Insects, 1935: "Sisyridae [spongilla fly] larvae go into the water for their food, freshwater sponges. It may surprise some readers to be told that we have freshwater sponges, but we do. The Sisyrid larva comes out of the water to spin the double-walled cocoon within which it pupates. The cocoon cover of Climacia dictyona is beautifully lace-like."
Sounded like a good match to me--especially since one of your other pictures showed the cocoon clearly next to water--and I just found this painting from 1901, which clinches it.
Spongilla flies, incidentally, are relatives of antlions and lacewings. Great find!

Amazing! Nice work, Charley!
- certainly looks like a very good match. I'll move this image

 
Nice Work!
Nice Work! I have never herd of a Spongilla fly.

I can't wait to find out what
I can't wait to find out what this is!! ^__^

cocoon
I have found 3 more and have collected one.

 
Are all the "hair-nets" this perfect?
It seems a lot neater than the other weevil nets we've seen.

 
Hairnet
Yes identical but somewhat smaller.
I am keeping it on my enclosed back porch in a plastic container with a screen top.
I noticed the neatness of these compared to the others also.

We've had some similar but brown
hairnets posted to Hypera here. It will be interesting to see if these are related.

 
Cocoon
At last a clue! There are weevils all over the place.
I will keep my eye on it.

 
Cocoon
I went back to check and someone has collected the cocoon.

!!
Keep an eye on it and see what it turns out to be.

Wow!
Very cool.

Wow!
Me too!
