Like most other sphinx moths, the waved sphinx (Lepidoptera: Sphingidae: Ceratomia undulosa) is a rather large insect. The individual shown here was about two inches (50 mm) in length, and wingspans typically reach 3-4 inches (76-102 mm).
This species gets its common name from the intricate wavy pattern displayed on the forewings. Individuals also feature a single, kidney-shaped white spot outlined in black on each forewing. Overall coloration varies quite a bit between individuals, and some are much darker than the one shown here.
Waved sphinx moths are one of the most common sphinx moths in North America. They’re found east of the Rockies in and around forests and woodlots where host trees are present. Adults probably don’t feed, but their larvae can be found on ash (Fraxinus spp.), oak (Quercus spp.), hawthorn (Crataegus spp.), lilac (Syringa spp.), and several other species.
