Thanks for commenting puckett.llewellyn.I'm not sure why they're on lupine. Maybe for pollen or nectar. According to BugGuide, they are associated with Asteraceae, such as goldenrods and asters.

Is she eating the Aphids off of that Beautiful Lupine?

Thanks much, Neil. I wish now that I had made a video of them.

Wonderful spotting, Brian. And I love their feeding etiquette. I'm sure I've seen humans engaging in the same practice!
