Readers’ wildlife photos

We have some photos and a story from reader Olen Rambow. His text is indented:

Attached are some wildlife photos taken in Shenandoah National Park in Virginia. I believe the butterfly is a female Eastern Tiger Swallowtail (Papilio glaucus), and the moth is a Royal Walnut Moth (Citheronia regalis). I was not able to identify the millipede. (I think it’s a millipede, rather than a centipede, as it appears to have about twice as many legs as body segments.)
I discovered that the millipedes above are not only aposematically colored, as they contain cyanide that makes then poisonous, but are also part of a Müllerian mimicry complex in which different species mimic each other’s color and pattern.
There’s a funny story behind the moth: We found it on our cabin doorstep in the morning and later saw that it was still there when we returned from a hike in the afternoon. I touched it with my finger, and it fell over onto its side, its legs twitching feebly. I assumed it was dying, and I took it inside, not wanting such a beautiful specimen to get stepped on or eaten by ants. My five-year-old son and I named it Charlie. For the rest of the day, Charlie lay on top of the chest of drawers, presumably dying in peace. Then at about 10 p.m., as we were drifting off to sleep, we heard a rather dramatic fluttering and thumping from Charlie’s side of the room. I turned on the light over the bed, and Charlie promptly flew straight into it, apparently in good health. My wife screamed, while my son jumped up and down yelling, “Charlie’s alive! Charlie’s alive!” I put him outside, and he flew off into the night. The next morning, he had returned to roost on our doorframe again. I guess the lesson I learned is that moths can sleep surprisingly soundly during the day.
I think the moth should have been named “Lazarus” rather than Charlie. Do you recognize the species? We saw this the other day:

    The moth looks a bit like the moth from a post with Mark’s pictures from a few days ago:

    “Anyway, here are pictures of the adult hickory horned devils, aka regal/royal moths shortly after their wings had expanded but were not yet inclined to fly.”

    I don’t know if this is the same moth or not.

      It’s the same moth.

    I think this may be a species of Eurymerodesmus. It’s at least a member of Polydesmida. Based on the bright colors it probably produces cyanide as a defense. Try smelling it and see if you get almonds.

    Nice shots. I can never get butterflies to hold still long enough for a portrait.

    Very interesting! Charlie was playing dead. an old trick that has served insects well since probably before the age of dinosaurs.
    When trying to catch an insect, I am sometimes still flummoxed by this technique of theirs. I would of course try to prevent them from flying up during capture, but I should be also prepared to catch them when they suddenly drop down.

    That millipede has the “don’t mess with me” colours.
