Found this one this morning. No clue what it is, but it was surely a strange looking blob on the leaf. If anyone knows, feel free to throw it out there.
Congrats! That's a giant swallowtail butterfly caterpillar. :) They look like bird poop to help protect them from predators. Check my comments on your butterfly picture yesterday (I think it was yesterday...)
@julienne1@gilbertwood@wingwatcher@milaniet Thanks all. Thanks Julie for the identification. My first thought when I first saw it, was exactly what you described it as. I'll have to keep an eye in that area to see what develops.
