Specimen type: Photograph
Observation notes: Found this attached to a Tulip tree branch. At the same time saw a perfect Eastern Tiger Swallowtail a few feet away immobile on a rock. Possible unrelated coincidence. There was another empty one attached to an adjacent branch on the same tree.

Coordinator notes: The photo is of a Callosamia cocoon, probably spun the previous fall. In the sighting locale, two Callosamia species exist, C. promethea and C, angulifera. The larva of both species feed on Tulip Poplar, the tree shown in one of the photos. Since C. angulifera cocoons are not typically attached to the host plant, and this would be near the northern limits of that species range, being rare, I believe this is a cocoon of C. promethea. C. promthea attaches its coccons to the host plant in the manner shown in the photo.
