I found this beetle by Washoe Lake near Reno, NV. Not sure what he is or if he’s native or not. Thought it might be a garden chafer beetle but that didn’t seem right. What do you think? Thanks!

Based on BugGuide images, we are somewhat confident this is a Little Bear Scarab, Paracotalpa granicollis, and BugGuide data has reports from Nevada. We do not want to rule out that it might be a related species in the same genus, like Paracotalpa ursina which is pictured on BugGuide and Paracotalpa leonina, though with the latter, BugGuide indicates: “A very early species, flying in January & February in Mojave desert areas of CA, NV, and AZ.”
Gene St. Denis confirms our identification in a comment.
I believe that you have a fine example of a Paracotalpa granicollis.
