Thanks for the reply, Walter.  I, too, was surprised to find the monarchs.  I know there are many thousands hanging on the trees of the central coast, but I didn't expect to see so many hanging around tress of the low desert floor.  Also interesting was how much intermingling was going on between D. plexippus and D. gilippus.  They really acted more like siblings than distant cousins.  I've run into D. gilippus many times in the low desert, often in large numbers, and I've seen the two species coexist before as well, but I've never seen them congregate in numbers together in the same location.  It was very cool.
