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.
European Glowworm
A well-known European firefly where only the wingless female produces a steady green glow. Males are winged but produce no light.
Did You Know?
Females glow for up to two hours each night to attract flying males, then stop after mating.
