Another cocoon: Mourning cloak

Nymphalis antiopa Mourning Cloak
My expert at BAMONA says, take in the cocoons and shelter them. It is amazing to watch.

I use an old aquarium, with an old window screen. Carefully removing the cocoon with tweezers, I tied a string to the threads on the end. Then, I taped it to a piece of vinyl, letting it dangle as it was.
There are two on the go here. The brownish one is a Mourning Cloak butterfly. The other black one is a Virginia Ctenucha.

Thursday night it began to change to black.
I knew it was nearly time.
They tell me they hatch in the morning.

Looks like a pretty, upside bat!

5:30 a.m.
My set-up: videocam on the tripod,
thermometer says 10 C., 'twas a cold night!

Sun is rising.
I had three helpers, with Daisy on-call in the Muskoka room beyond.
I set the camera to run, popping back over to it to shut it off and begin a fresh clip. I find this works better. Then, discovering that the spare battery was dying, I'd cleverly replaced it first, I figured I had to plug it all in. That was better.

Time passed. I read yesterday's paper, did some computing, today's blog post, had 3 cups of coffee. By 7:00 a.m., hubby got up. Still nothing. By 9:00 hubby was watching tennis. Raonic won. At 9:30, I figured I'd better get my workout done. When I came back upstairs, it had broken free!
It hung on it's cocoon for over two hours. I moved it to the railing, to be out of sight of cats.

I waited all morning! The visible process took 10+ minutes, I sped it up 4 x's the speed. It took 2+ hours to rest and then fly away.

Mourning Cloak caterpillar

Mourning Cloak
Nymphalis antiopa

I was weeding and found this pokey thing in the garden. I had it ID'd by BAMONA, I'm so bad with that!
 
This is the adult! They over winter, which is why they can look so frowsy, and are often the first butterflies we see in the springtime.
