Some of individuals are much darker (with the black base color showing through the elytral pubescence). I have also seen specimens that almost look gold. I found this one just before dusk up American Fork Canyon (in the same place as the giant ladybird beetle of my last post).
The habitat is spare scrub oak and sagebrush with Douglas fir and boxelder along the canyon floor. It's always a good day when you find bycids about.
