The Southern Dogface - Zerene cesonia - flies in the deserts to the east here in Southern California, including Cactus Spring Trail south of Palm Desert. These photos are both from Arizona - Boyce Thomspson Arboretum on September 25, 2007.
Southern Dogface - Zerene cesonia. In a few hours at the Arboretum I photographed about a half-dozen or so species that would be much harder to find in our state. I even saw two species I needed in the parking lot where a plant sale was in progress. I highly recommend a trip to the Arboretum, especially in September.
