Walnut Sphinx Moth
A beautifully cryptic hawk moth with scalloped wing edges and mottled brown, gray, and lavender patterns. It rests among leaf litter where it is nearly impossible to detect.
Did You Know?
The walnut sphinx caterpillar can produce a high-pitched whistle by forcing air through its spiracles, startling birds and other predators.
Atlas Moth
One of the largest moths in the world by wing area. Adults have no mouths and do not eat, living only 1-2 weeks on stored fat. Wing tips mimic snake heads.
Did You Know?
The atlas moth has no mouth — as an adult, it cannot eat. It survives entirely on fat stored during its caterpillar stage, living just long enough to mate.
