Giant Swallowtail

Having a wingspan up to seven inches, this butterfly certainly earns the name Giant Swallowtail (Papilio cresphontes). It also holds the title of largest butterfly in North America.

The larval host plants of Giant Swallowtails consist of many trees in the citrus family including, here in Virginia, the Common Hop Tree (Ptelea trifoliata). These caterpillars have a clever camouflage, mimicking bird droppings. They live as caterpillars three to four weeks.

Giant Swallowtails will take part in an activity known as puddling, taking salts and minerals from moist soil or sand, and manure. They only live as adult butterflies six to fourteen days. During that time they seek nectar from flowers such as Azalea, Bougainvillea, Japanese Honeysuckle, Goldenrod, Dame’s Rocket, Bouncing Bet, and Red Clover.
