Spring's return stirs wintering mourning cloaks





One of the first butterflies to be seen fluttering about in late winter or early spring is the mourning cloak (Nymphalis antiopa).

The reason? They get a head start being one of the few species that overwinters, i.e. hibernates as adults.Mourning cloaks are widespread: tundra south to central Mexico and in Eurasia, primarily Scandinavia. In Sweden they are known as sorgmantel literally "mourning cloak" presumably a name that comes from their cloak of dark purple-brown color.

Host plants for the caterpillars: Female mourning cloaks lay their eggs on willows, aspens, elms, cottonwoods and paper birches, but seem to prefer assorted willows.

On Tuesday, March 29, I saw a mourning cloak flutter trough the plaza in front of the Visitor Center for the first time this season.
