browsing: Black Swallowtail
Black Swallowtails overwinter as pupa inside a chrysalis. Caterpillars attach their chrysalis to plant stems, sticks and rocks, usually within a few feet of the ground. The chrysalis may be brown or green to blend in with the surroundings. This is a great reason to leave garden debris in place until spring weather warms enough for insects to emerge.Click here for range map, photos, and natural history.
