I found these caterpillars eating the leaves on a small, very thorny bush, about 2’ tall on the side of a sandy road in Melbourne, FL. The caterpillars are very flat and not hairy, that I can see.

Giant Swallowtail Caterpillar

Dear Always Curious,
This is the caterpillar of a Giant Swallowtail which is commonly called an Orange Dog.  The caterpillar has several survival mechanisms, and one is that it appears to resemble bird droppings, thereby avoiding predators.

Thanks for the  giant swallowtail ID.   Your website is awesome!  Always curious
