Red-Spotted Purple
Today I was visited by a red-spotted purple butterfly. These butterflies are noted for feeding on sap and rotting fruit. They do well in urban areas where many of the street and backyard trees, such as black cherries and willows, can serve as hosts for the caterpillars. The adults are not known to be toxic and are considered to be mimics of the toxic Pipevine swallowtail.
