I did a survey of the chrysalis cases attached to my buildings today.

I had two emerge today but there are still many to come out. The process 
seems to take longer than mentioned in most sources (10-14 days). Some 
of the chrysalises have been hanging for over two weeks. Caterpillars 
are still climbing and attaching to overhangs. Many are rather smaller 
than the others that started earlier.

Lately, we have been having about two every day emerge.

Today, I counted:
Green Chrysalises = 71
Empty Chrysalis shells = 29
Caterpillars attached = 11
Dead Chrysalises = 5

Not all chrysalises survive. I saw a Blue Jay take one off the side of 
the building. I don't know if it had a gagging response since it flew 
away immediately. A couple have had damage and a couple just darken and 
no Monarch emerges before it decays.

We will continue to observe; it is fascinating.
