When cleaning my deck this rolled out on the floor. One half was moving (the pointed end, back and forth) but no legs or eyes seen. The other half was sort of hard like a shell. It's the length and width of my little finger. As far as I could tell it hadn't attached itself to anything. If it's a chrysalis can you tell what kind of butterfly it could be? I put it under a rose bush last night but it isn't moving anymore. Is it dead or in metamorphosis? What should I do with it?
I'll load a second image...
