We've seen a number of small insects visiting this member of Anthemideae and I managed to get a picture of just a fraction of the diversity. It's an important reminder of the value of plants that flower late into the season.
I wish I could be more specific in naming the plant but it was given to me by someone who had the ID wrong. It's great to swap plants with folks but if you're unsure of their accuracy it's worth potting up their gift until you can observe further identifying characteristics. This one will definitely be planted this fall.
Excellent observation! There are a number of members in Syrphideae and we're lucky enough to have a few that we've been able to identify. They aren't just pollinators though, they're an integral part of any Integrated Pest Management plan in regions where they're native, as they are voracious predators in their larval stages.
I didn't know about that part! Cool!
It's always the ones you least expect
