Spring at Pena Blanca Lake is a very pretty time to visit. We will be looking for butterflies as we walk around the north and west sides of Pena Blanca Lake. We will park at three different locations on the lake and walk for periods of time at each stop. Our last stop will be at the launch ramp facility at the end of the paved road. From there, we will walk south along the west shore of the lake towards the dam. On past trips in the spring we have identified 30 or more species, including various Sulphurs, Blues, Fritillaries, Buckeyes, and multiple species of Skippers.
The first stop will be walking on mostly level dirt ground, the second stop walking on a paved trail, and the optional third stop will be hiking the dirt trail on the west side of the lake, which has three short, steep sections that can be difficult to traverse.

The day started out cool and breezy, but it eventually warmed up and turned quite pleasant. About of a third of the butterflies and most of the odonates identified were seen after lunch on the trail downlake from the boat launch.
