seen visiting mock orange blossoms on the first or second day they were blooming
4 years ago I called these "denticulatus" but I'm unsure. These are other photos from the next day. Still 4 years ago but I got behind during that pesky pandemic.
2 or 3 females observed foraging on Claytonia. No males seen, though there were some males of a different species visiting the flowers and investigating the area. The females differed in hair color - this individual was more off-white while the other(s) was white/gray. One small Nomada seen briefly also, but couldn't get a good look at it.
