10 AM - 1:15 PM. Sun with high cloud, 71-77 degrees. Much of the purple loosestrife done; each of the remaining patches with bloom was inhibited by 2-5 large mantises. Bidens and Purple gerardia in full bloom. After seeing only beat-up Eastern Tigers for several weeks, have seen quite fresh individuals the last few times out; perhaps the recent rains stimulated a late emergence?
