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.

Found in the evergreen woods on an overcast day amongst some P. menziesii, Gaultheria shallon, and Polystichum munutim.
Trumpet or vase-like growth with black inner color and gray external color. Undulating cap margins and some with tomentose scales on the inner surface as seen in picture 2. Tastes delicious!
