Life in a Sap Bucket

Eupilia vinulenta - Straight-toothed Sallow

I found this moth in maple sap bucket at Westwood.  I thought it was dead, but it revived after being in my hand for a few minutes.  It over winters as an adult, feeds on tree sap, and has a number of adaptations for the cold, which you can read about here (you'll have to download the pdf).
