Our kindergarten classes were outside on the playground at recess and found this bug. It has spots that appear to be a mouth and eyes on its head. We looked it up and thought perhaps it was a Pandora sphinx caterpillar but aren’t sure. My fellow teacher and I would love to know what it is so we can tell our classes more about it!

Dear Welch Elementary Kindergarten,
This distinctive caterpillar is a Spicebush Swallowtail Caterpillar. The false eyespots might help protect the tasty caterpillar from predators like birds that may mistake a toothsome caterpillar for a much larger and potentially dangerous snake. Spicebush Swallowtail caterpillars feed on a variety of trees, including “Spicebush (Lindera benzoin), Sassafras trees (Sassafras albidum), Pondspice (Litsea aestivalis) Red, Swamp and Silk Bays (Persea spp.); perhaps prickly ash (Zanthoxylum americanum), Tulip tree (Liriodendron tulipifera), Sweetbay (Magnolia virginiana), and Camphor (Cinnamomum camphora)” according to BugGuide. They begin life as green caterpillars that are well camouflaged, but as the time for pupation nears, they often turn orange, leave the trees they have been feeding upon, and find an appropriate site to metamorphose into a chrysalis. The adult Spicebush Swallowtail is a beautiful black butterfly with colorful markings.
Thank you so much! We looked it up on the Smart Board and discussed the life cycle. We printed a picture of the butterfly so we can watch for them in the spring.
You have a great site!
