Sometimes you take what you can get
These are truly amazing creatures! During rainy weather butterflies will perch on the underside of a leaf or crawl deep between blades of grass and wait. When temperatures drop below freezing they will find crevices in structures such as holes in trees, or hunker down deep in leaf litter. When the weather warms again and they bask in the sunshine they will flutter.
But after the freeze there are very few nectar sources. Poor butterflies take what they can get from the spent blooms. Just look at the skipper above searching for nectar in an azalea bloom after the freeze.
Violas are one of the few plants still blooming in my garden right now.
