Swallowtail Caterpillar

Thats not bird droppings…its a giant swallowtail butterfly caterpillar!

The giant swallowtail butterfly’s caterpillars are unmistakable.  They look like bird droppings.  These caterpillars feed on citrus plants hence the nickname “orange dog.”  The caterpillar below is feeding on Hercules club.
