Walnut Sphinx Moth
Other Name(s): Sphinx Moth; Hawkmoth
Characteristics: Native to deciduous woodlands, Walnut Sphinx Moths are highly common throughout Missouri with limited appearances in certain portions of other states east of the Rocky Mountains.
Colors of the Walnut Sphinx Moth differ from sample to sample so this makes identification of this species a bit more challenging than one would like. Overall, they maintain a light or dark brown coloring with bands of white or even pink. The patterns along the wings may or may not appear highly visible at first. With wings extended, these insects tend to take on a more rectangular shape when viewed from above. Their antenna are comb-like and their bodies appeared to be covered in a thick hair with the exception of their leg ends.
Adult Walnut Sphinx Moths do not feed and produce in a single brood in the northern states, between May and August, while producing two broods in the south, from March through October.
Walnut Sphinx Moth caterpillars host inside of walnut, butternut, hickory, alder, beech, hazelnut and hop-hornbeam. They may make "squeaking" sounds when disturbed.
