In February (this year) I posted a picture of Ellychnia megista that I found in the coastal redwoods of California. About a month ago, I came across another Ellychnia (E. californica) species in the Sierra Nevada above Bass Lake.
We were camping at about 5,000 feet near a small shaded stream with several broad-leaf annuals growing along the bank. I discovered it resting on a mossy stone. You can see that the black band on the pronotum is less parallel than in E. megista. It's a bit more triangular. A pretty beetle for sure.
