Motorist passing through Central Texas and the Hill Country may have noticed large numbers of butterflies swarming the roadways and countryside. The winged critter is known as the American Snout and it is on migration.
Upon close examination the snout has long slender mouth parts, which together with its antenna, give the appearance of a stem or twig. They use this to their advantage and hang upside down at times giving them excellent camouflage from predators as they take on the look of a leaf on a tree. Their wings are dark brown or black with creamy orange and white markings.
According to Dr. Robert Svoboda in a paper he published in 2006, said the snouts migrate in large groups, with no established pattern.
