The name Pleasing Fungus Beetle derived as they are generally found where various fungi are present. There are many varieties of them, this one is a Gibbifer Californicus species. I found this one in a higher elevation rock forest area where there were many dead trees and various mushrooms present.

I AM pleased. I’ve never heard of a Pleasing Fungus Beetle, and I’m so glad you’ve introduced me to them. They are stunning!
When you say “a higher altitude forest”, was it a Ponderosa/Jack Pine forest, or higher — spruce-fir?
