Determined by Dr. Eric Fisher who said: “This fly is Holopogon sapphirus (and was actually described – in part – from Madera Canyon). Main reason it hasn’t been photographed before is that it is fall-active–found only in September and October. It perches on twig tips of leguminous plants, just like many other Holopogon.”
