Recent
butterfly (and moth!) sightings at Fermilab

This past weekend marked the first warm weekend of the spring and the
first local butterflies! A short walk through the woods at
Fermilab revealed many Eastern Commas (winter forms) and Mourning
Cloaks. Since these species overwinter as adults and
become active with the first sunny, 60 F + days of the year, they are
often the first butterflies that I see here. The flashy presence
of the orange commas resting on the brown leaves in the woods can be
quite striking. Below is a photo of an Eastern Comma taken
yesterday.
