Cigartree (Catalpa bignonioides)

The primary food source for the sphinx moth caterpillar is the leaves of the Catalpa tree, also known as the cigar tree. Native to the southeastern United States, this tree is often used as a shade or ornamental tree due to its large, heart-shaped leaves and clusters of showy flowers. The tree produces long, cigar-like seed pods, and its leaves release an unpleasant odor when crushed. The caterpillars that feed on these trees are also popular as fish bait.
