Driftless Prairies: Native Habitat Restoration

Nature inspires awe!

Papilionidae – Swallowtails

These butterflies are the largest insects. Swallowtails overwinter as pupa and when they emerge they lay their eggs on the tips of young host plant leaves. As a defense mechanism so birds don’t eat them, many of the caterpillars look like bird droppings. They also can emit a foul odor and startle predators with a brightly colored defense display that looks like the forked tongue of a snake.
