I saw what was likely the same bee two times throughout the day. I saw her once in the morning doing typical nest searching behavior likely to parasitize another Bombus sp. I got one bad photo, so I'm leaving it out.

I saw this bee AGAIN in the afternoon, primarily nest searching. Luckily she stopped on the Sundial Lupine to forage so I could get some photos. She then investigated a hole near the plant she was foraging, only for about 30 seconds. The last two photos is her coming out of said hole.
