On one of our walks the other day we saw so many things out enjoying the sunshine with us. It had warmed up enough for a little snake to be stretched out across the gravel trail at the marsh. It slithered away before we had a chance to take a photo. Then a ruby-crowned kinglet flitted about from tree to tree with wonderful exuberance. So many people were out walking as well. Everyone we crossed paths with smiled and said hello in that warm and cheerful way. Ah the very air was an invitation to the delights of the moment. Then we saw it... a butterfly. A butterfly in winter? No way. How is that even possible? But there it was floating in the air before us, and then landing on the trail. When I took a good long look at it and photographed it a few times, I thought I recognized what it was... a Mourning Cloak. I had seen one once before more than a decade ago in Port Townsend, WA.
So, when we got home I googled around and verified it was indeed a Mourning Cloak. What is a butterfly doing out in winter? How is this possible? So I found some wonderful information about this species.
"The Mourning Cloak overwinters as an adult, which requires quite a bit of specialized biology. Hibernating adults can survive through the winter by use of “antifreeze” chemicals (glycerols) in their blood. They locate sheltered tree crevices where they will spend the winter.These butterflies even over-winter in as cold a place as Manitoba. Such strong and hearty little beauties they are.
On sunny days, even while there’s snow on the ground, some adults will emerge to feed on tree sap, especially oaks, and then return to their sheltered winter hiding place."
There is something about seeing a butterfly in winter that is so full of the promise of spring. The little hidden lives and seeds out there, waiting for the right moment to emerge. We were so happy to see it, we said hello and thanked it for showing up. Then we walked on.
