Thank you for taking the time to help. I did spray water and it did soften but still would not release. I eventually took a tiny pair of surgical scissors and clipped it close to it's little body. At least he was free of that weight dragging on him.
It cannot fly and I don't think it can even take up nectar. The proboscis doesn't seem to go down into a flower. He keeps uncoiling and recoiling it and it looks split on the tip (maybe they're all like that) and his left antenna is hanging in a droopy way down the side of his face. He tries to fly and crawls around on the milkweed but flutters to the ground each time he attempts to fly.
Since it doesn't appear he can nectar, I think the most humane thing is to put him down in the fridge/freezer. How I hate this.
We did release 2 healthy girls and a boy today. We have three more chrysalis to eclose to finish up all that we brought in as eggs. So far we've released 49. If the remaining three are healthy, this will be 52 Monarchs raised and released this summer.
