MBP - Mourning Cloaks
Incoming reports of Mourning Cloaks are a sure sign of spring. Overwintered adult Mourning Cloaks are among the very first butterflies to become active as temperatures warm in early spring. This is one of many species that benefit from "leaving the leaves", not overly tidying yards in autumn and leaving leaf litter for overwintering species that need it.
The hardy butterfly is Holarctic in its distribution, found throughout much of northern Europe and Asia in addition to most of North America. (I recently saw my first of the season in Monterey, California as well!) This butterfly can be found basking in open woodlands or attracted to rotten fruit or sap runs on trees.
The species seems to favor willows (Salix) as host plants, but will also use aspens (Populus), birches (Betula), American Elm (Ulmus americana), and hackberry (Celtis).
