Imperial moth (Eacles imperialis), Fishers Island, NY, July 2018.Â
With the spring semester at an end, and maintaining social isolation, I’m going through old photos that I haven’t uploaded or only uploaded to iNaturalist.Â
The coloration of imperial moths are believed to serve as a form of crypsis (camouflage), as the golden yellow and brown speckling pattern mimics the appearance of dead leaves when at rest. This species is somewhat sexually dimorphic, with the males appearing to have more abundant and darker speckling on their forewings than the females.Â
 As caterpillars, they feed on many deciduous trees, including basswood, birch, elm, hickory, locust, maple, oak, sassafras, sweetgum, sycamore, and walnut. They also can feed on evergreen trees like cypress, cedar, and pine. During my time in the Mid-Atlantic, they showed a preference for white pine and oak. The adults, in comparison do not feed, lasting for only a short time (a matter of 2-3 days) to find a mate.Â
One generation in the eastern US, with adults by mid-summer, and eggs into August. Caterpillars overwinter as pupae in the soil.
