Larva was found on American beech. The larvae feed on elm, hickory, beech,

The Pterourus glaucus (Eastern Tiger Swallowtail) caterpillar to the right displays the false eyes and foul smelling osmeterium (orange, forked organ) common to many species in this genus.
The bright green colouration also blends well with the foliage while this caterpillar rests on a central leaf vein. This one has probably left the foliage looking for a place to fasten itself for pupation or was dislodged during recent hurricane.
