I was able to confirm that this is an Andrena prunorum nest as I saw her enter after this Nomada left.
With Collinsia parviflora in boulevard native plant pollinator garden
Around 7 in this area.
I'm useless at IDing sedges so I'd really appreciate some help on this!
Growing at mid-elevation site. Previously dry Douglas fir/Arbutus forest, bordering a rock outcrop with GOE associated species.
The area was logged last year, and the native sedges and grasses have really taken off with all the extra light. There's also a bunch more invasive plants in the area now though.
