When packing up for a short paddling trip 9/12/15 I noticed a monarch chrysalis on the side of my canoe. I carefully removed it and using masking tape attached it to a wire suspended from my house. Weeks passed and other monarchs matured and emerged but this chrysalis turned very dark, then faded to tan. I eventually brought it inside where it hung on my refrigerator. To my surprise I noticed dozens if not hundreds of tiny wasps emerging today. While heading out the door I popped the chrysalis into a glass tube to photograph at work. During my 30 minute drive another 20-30 wasps emerged.

I forwarded these photos to the Monarch Joint Venture at UMN and Carl Stenoin was kind enough to reply: "These are probably Pteromalus cassotis, but I can't be 100% sure without seeing them under a microscope..."
