Trip description: 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. Past trips have identified various Sulphurs, Blues, Fritillaries, Buckeyes, and multiple species of Skippers. In past years, we saw 29 butterfly species and a small number of dragonflies

Type of terrain: The first stop will be walking on level dirt ground, the second stop 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.

Trip Butterfly Reports: 

SEABA members and four people new to butterflying spent about 4 hours searching the edges of Peña Blanca Lake for butterflies on a beautiful, calm, and sunny spring day. Although it was somewhat dry in the area and nectar sources were not plentiful, the group located 34 species.
