We recently spotted an eastern giant swallowtail (Papilio cresphontes) at the Morris—a rare spotting in PA! The eastern giant swallowtail is the largest butterfly in North America, with females averaging a wingspan of 5.5 inches and up to 6.9 inches while males average 5.8 inches and up to 7.4 inches. These butterflies mostly inhabit deciduous forest and citrus orchards. They feed on plants in the orange family, including common pricklyash (Xanthoxylum americanum) which we have here at the Morri

This cute little giant swallowtail (Papilio cresphontes) caterpillar hatched on my desk today! It's spiny and adorable and smaller than a grain of rice right now, but in a couple weeks it'll look like a big glob of bird poop. Much cuter as a baby. | Be Smart
