Hanging insect egg

Any idea what left this egg?

Moved (again)
I wrote to Dr. Scott Shaw at the University of Wyoming because I was suspicious about how much this cocoon differs from the confirmed Meteorus cocoons I have seen, and here is his response:

"Your suspicion is correct, the lower cocoon is not a braconid. The lower photo, with the more oval cocoon with a lateral band is Ichneumonidae, from the subfamily Campopleginae. It is definitely not Meteorus... Your website link mentions that this cocoon image is similar to one identified as Meteorus in a publication by Wagner. I did not follow up on that, but I’m copying this correspondence to Dave Wagner, just in case it was not identified correctly. This one at least is definitely a campoplegine ichneumonid."

Moved
Moved from cocoons. This does look very similar to the Meteorus cocoon on p. 23 of Wagner, although very different from the one here.

Moved
Moved from Braconid Wasps.

sticking my neck out
here but it looks like the cocoon of a parasitoid wasp, Ichneumonidae.

Braconidae.
I am willing to suggest it is the cocoon of a braconid wasp like Meteorus (great name, obviously!). Nice image. We don't get many shots of pupal stages, period.

 
Found something similar recently
It is currently in an enclosure in my backyard, hopefully 'hatching' soon. I'm starting to wonder if it's still viable though. One interesting thing I noted was that if I tilted the container it was suspended in so that it touched the side of the container, it would 'jump' much like a mexican jumping bean.
