Just wondering what this is and what it will be
This is the caterpillar of a Mourning Cloak, sometimes called a Spiny Elm Caterpillar. The adult Mourning Cloak is a lovely butterfly that hibernates over the winter, and they are sometimes seen flying on warm, sunny, winter days, even when there is still snow on the ground. Before flowers begin to bloom, they take nourishment by drinking sap that flows from the trees in the spring.
