Found the caterpillar on September 15th 2023. I put it in a jar to observe and it promptly spun a cocoon. It decided to overwinter and has now hatched on April 24th. I’m not sure how my temperature controlled house altered the hibernation period. I watched it for the day and then released it that night knowing it had an extremely short lifespan. Below I will include a timeline of each photo for reference:

I think it is a male, I’m not confident. Please verify.
