I found this cocoon today in deciduous forest in Toronto suburbs approx. one meter above ground. Please help me to identify it, it should still be alive as it is quite heavy, not dry. Should I still keep it outside or bring inside to emerge earlier ?? Thanks in advance.  |

Looks like a polyphemus. Keep it somewhere protected but where it can still get exposed to outside temperatures so it will emerge along with the wild population. When you shake it, if it makes a thud, it’s alive. If not, but it is still heavy, it probably is packed with parasites.

Yeah it is on the small side. Hard to gage as I don’t have one handy for comparison. I have some at home. Will try to remember to look tonight. You could always open it and see. Would also tell you if it is a male/female.

A number of years ago I found to rather small cocoons and thought they were Polyphemus. In early May out came to Automeris io moths.
It is difficult to determine size from your photograph.

Using the ruler in the photo, the body of the cocoon is about 1.5 inches. Rather small for a polyphemus.

It is spring and the weather is warming, if the cocoon is viable, you should know soon.
