My 7 year old daughter and I found a monarch caterpillar a few weeks ago and brought it inside in a net cage we'd previously used to raise painted ladies.
It changed into a chrysalis three weeks ago today, but has not emerged. It has none of the obvious symptoms of death - it's not all black (but the top of it has a black blotch on it) and there is no string hanging down. It doesn't smell bad, and is still hard all over.
I can see the pattern and folds of the wings, but it is overall dark bluish grey (changed from more green a few days ago.)
Is it possible it will still hatch? Three weeks is VERY long, and it hasn't been particularly cold or rainy here (NW CT), which I've read could contribute to a slower transformation.
