A Visit to Granger Lake

Previously I had found mercurialis on a stony tributary northwest of the lake. That was my very first encounter with the species. A month or two ago someone observed one along Comanche Trail on the south side of the lake. I wanted to confirm that and did. I also found Arctosa littoralis and a Schizocosa avida juvenile there. I first checked out the rocky area next to the dam on the south side of the outflow and a pebbly beach on the lake next to the south end of the dam. I found mercurialis and only mercurialis in both locations, especially the latter. My next step is to tour western Texas looking for the other lapidicina group species, maybe next spring when the days are warmer and longer. Before leaving I'll check other people's observations and satellite views to figure out my route and stops. Maybe then I'll have enough detailed images to work out the species
IDs. Every little clue will be needed.
