EXPLORE #333 on August 1, 2009.Found this Black Swallowtail Caterpillar on the fennel I planted in my backyard. Fennel and parsley are good host plants to attract the Black Swallowtail.
Black Swallowtails sharing the sweets of a thistle flower (from the archives). Photographed along the Shane Wilbanks Trail near Lake Grapevine in Texas.
