Mourning Cloak Butterflies Out From Under Tree Bark
Mourning Cloaks have recently emerged from under loose bark where they hibernated all winter. These early flyers, along with a few other species such as commas and tortoiseshells, have a jump start in the spring due to their not having to go through metamorphosis like most butterflies. Born last summer, Mourning Cloaks live for roughly ten months (longer than most butterflies), overwintering and breeding and laying eggs soon after appearing in the spring. This summer their larvae will feed on willows and poplars before pupating and emerging as adults in time to seek shelter for the winter. With snow still on the ground, nectar is quite scarce, leaving butterflies that are active this time of year dependent on tree sap available where branches have broken for much of their sustenance.
