Thin-neck Cave Beetle
A narrowly endemic cave beetle with a distinctively slender pronotum. It inhabits caves in the Appalachian karst region.
Did You Know?
Its narrow neck (pronotum) helps it squeeze through tiny fissures in cave rock.
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.
