Yellow faced bumble bee in a California poppy

Ah, my first observation of the year of a Yellow-faced bumble bee Bombus vosnesenskii in a California poppy in the garden.

I rarely see other bees in the California poppies.
The Yellow-faced bumble bees visit them often throughout the day.

I'm so glad to see these poppies reseeding themselves throughout the garden, providing so much pollen for these bumble bees.
