A medium butterfly with orange and black wings that often gets mistaken for a Monarch. It can be distinguished from the monarch by its smaller size and the postmedian black line that runs across the veins on the hindwing. The viceroy’s wing color ranges from tawny orange in the north to dark mahogany in the south. The caterpillars sequester the salicylic acid in their bodies, which makes them bitter, and unpalatable to predators. As further protection, the caterpillars, as well as their chrysalis stage, resemble bird droppings.
