One yard in our neighborhood has a huge butterfly bush. Miz Flora is torn between liking it and not, because of course the plant isn’t a native species. But the hundreds of tiny blossoms attract and feed more insects on one plant than many natives, so I think it’s worthwhile. Especially when I got a glimpse of this moth.
We had to follow his quick movements for several minutes before figuring out it’s an insect, not a hummingbird. Our best guess is hummingbird moth, but if you have a positive identification, please speak up and post!
