Specimen type: Photograph
Observation notes: on turpentine broom, plum canyon heavy summer monsoons although scattered, have the shrubs doing great, a few annuals and some grasses. light fall rain in the fall helping some also. hot day many species out this day highlight of trip was we finally found calif, giant skipper. there were several larva on this shrub, and others.turpentine broom, there hard they look like dried up sticks, unless they are blooming. then wow very cool. the larva chew the bark off the more tender stems on the end of stems. this plant needs no leaves, gets all the sun it needs without them. water is the limiting factor in this dry climate. once we started to recognize this plant we started seeing lots of it this larva also comes in mostly black form, we could submit that also.
