New species of tiger swallowtail butterfly identified in eastern North America

A research team has identified a new species of tiger swallowtail butterfly living in eastern parts of North America. In their study, published in the journal ZooKeys, Julian Dupuis, B. Christian Schmidt, Charles J. DeRoller and Xi Wang captured and compared samples of Papilio glaucus and Papilio canadensis hybrids and compared them with both species, finding evidence that the hybrid butterflies were actually a unique species.
