The first-instar caterpillar that emerges from the egg is pale green or grayish-white, shiny, almost translucent, with a large, black head. It lacks banding coloration or tentacles. The larvae or caterpillar eats its egg case and begins to feed on milkweed in a circular motion, often leaving a characteristic, arc-shaped hole in the leaf.

Milkweed, of course, is the only food that monarch caterpillars eat, making it crucial for their survival. But here we come to the struggle between creating habitat and pretty landscapes in our yards.
More than 450 insect species feed on A. syriaca, including flies, beetles, ants, bees, wasps, and butterflies.It is among the most important food sources for monarch butterfly (Danaus plexippus) caterpillars in the northeastern and midwestern United States and is one of only three milkweed species on which the eastern monarch migration largely depends.
By eating some of these toxic plants, the caterpillars sequester aristolochic acid which renders both the caterpillars and the butterflies of some of these as toxic, thus protecting them from predators. [16] Similarly, the Parnassius smintheus sequesters sarmentosin from its host plant Sedum lanceolatum for protection from predators. [17]
Caterpillar and adult monarch butterflies store cardiac glycosides from milkweed, making these organisms distasteful. After eating a monarch caterpillar or butterfly, the bird predator will usually vomit, leading the bird to avoid eating similar looking butterflies in the future. [ 35 ]
Its wings feature an orange and black pattern, and over most of its range it is a Müllerian mimic [4] with the monarch butterfly (Danaus plexippus). The viceroy's wingspan is between 53 and 81 mm (2.1 and 3.2 in). [5] It can be distinguished from the monarch by its smaller size and the postmedian black line that runs across the veins on the ...
