Butterflies at Big Meadows

On Saturday, August 21, the Rivanna chapter of Virginia Master Naturalists hosted a butterfly walk. The outing was organized by John Holden and the hike leader was butterfly extraordinaire, Linda Marchman.
The group of 15+ walked along a gravel road on the west end of the meadows, giving us access to the meadow wildflowers and butterflies on both sides. Some species, notably the red admiral, were enjoying the minerals in the road. Thistle and white snakeroot were in full bloom, and dense patches of these plants provided the most variety.
We quickly exhausted the two hours allotted for this walk. The plan was to take the gravel drive to the woods, pass through a fern meadow forest, and take a meandering route through the heart of the Big Meadow to return to the parking lot. The butterflies had other plans for us!
A few hungry and thirsty die-hards did stick around to complete the hike. Two additional species were spotted, the common wood nymph and the gray comma (a really cool find!).
