Arctic Grayling
A pale grayish-brown butterfly with a translucent, papery wing quality and subtle darker striations. Its cryptic appearance makes it nearly invisible on lichen-covered rocks. Adults are extremely wary and difficult to approach.
Did You Know?
When this butterfly lands on lichen-covered rocks, it tilts sideways to align its wing veins with the rock cracks, achieving near-perfect camouflage.
Merveille du Jour
A strikingly camouflaged moth with green and black lichen-like patterning on its forewings. It rests on oak bark where it becomes virtually invisible.
Did You Know?
Its French name means 'marvel of the day' due to its extraordinary camouflage.
