The title here sounds a bit like Aspirin (acetylsalicylic acid...which I can say more easily than the above Latin name…just barely), but it’s a moth…and a beauty at that.
Grape Plume Moth on a milkweed leaf.I’ve not done much mothing this summer, but this was pretty easily captured. I’ve seen a few different insect species on the milkweed but nary a Monarch caterpillar or butterfly. I saw a flash of orange the other day, but it was a Spangled Fritillary. This was a first of the species for me and I should be happy, but I’d honestly rather have the Monarch.
