"Coming in for a landing"
Native pink azalea (rhododendron prinophyllum) with native pollinator preparing to go to work.
This native shrub is usually found on north-facing slopes near running water. Blooms emerge in early spring in clusters (or "trusses") of 5-9 blossoms. This specimen shows blooms in all stages, from newly-budded, to fully open, to pollinated, withered and headed toward seed formation.
I'd love to say that I carefully planned and timed this shot to catch the incoming insect, but it was pure coincidence -- I didn't notice it until reviewing images from the days outing.
