We came across yet another caterpillar at Stateline Woods, so I thought I'd pass along the photo and the identification. This is the photo of the caterpillar of the Black Swallowtail butterfly. The Black Swallowtail is mostly black with a blue tail and mimics the look of the Pipevine Swallowtail Butterfly.
As butterflies (and caterpillars) they feed on the parsley and Rutaceae family of plants giving them a "yucky" taste--if you are a bird! We found this fellow on Queen Anne's Lace (in the carrot/parsley family).
Fall has arrived--so please let us know if you are interested in learning about more ways to attract butterflies/caterpillars to your yard--our Landscape Visionaries team would be happy to help.
