Coordinator notes: This butterfly is a Compton Tortoiseshell. Though it seems remarkable to see butterflies in Saskatchewan at the height of the winter, this butterfly does hibernate and appears to have come out of hibernation due to the recent warm weather. You can often find these butterflies most fresh in July and August but hibernating specimens can often be seen later in the fall to June of the following year. This particular individual shows some wear indicative of hibernating.
