Advertisement I took the following photos this past weekend along Lake Texoma. My finace and I were in the area searching for tarantulas when we decided to hike down to the lake for a swim. After cooling off I started to explore the rock cliffs along the lake and came across a few extremely large aggregations of harvestmen. I've read about such aggregations, but this was the first time I have witnessed one myself. Apparantly, this behavior is a way to conserve moisture. Enjoy!!
