On my visit to the Sagawau Canyon waterfall, you can imagine my surprise when I encountered the same ailanthus webworm moth from the previous photo (and from the photo in 2010.) However, when I looked up the photo from 2010, I found that the photo was from the Sag Quarries Forest Preserve, which is right next to the Sagawau Environmental Learning Center (where the canyon waterfall is located).
This moth wandered all over this particular group of blossoms, seemingly enjoying the buffet. I would love to read an explanation of the coloring for this moth; it doesn’t appear to blend into any flower that I’m aware of.
