A few weeks back, Nan at Shady Grove Farm in Kentucky sent in a photo of a monarch caterpillar preparing to pupate. Unfortunately she missed the transition from caterpillar to pupa, which happens in a flash. However, she kept track of the date, hoping to catch the emergence of the adult butterfly.
The reference she used said pupation would take 9-14 days. When those days came and went, Nan worried that the pupa had died. Still, she kept watching and on day 23 she was rewarded with a new butterfly. Her photos are below.
At nearly the same time, Debbe sent this photo of a monarch caterpillar forming a chrysalis in Delaware. The process is about mid-way through and you can still see the caterpillar in the top half.
Thank you Nan and Debbe for the pics!
