The Gray Cracker (Hamadryas februa) is a medium-sized butterfly in the Nymphalidae family, known for its exceptional camouflage and unique behavior. Like other species in the Hamadryas genus, it produces a distinct "cracking" sound, particularly during courtship or territorial disputes. The upper side of the wings is mottled in shades of gray, black, and white, resembling lichen or bark, providing excellent camouflage. The Gray Cracker is typically found resting head-down on tree trunks during the day. Its cryptic coloration makes it almost invisible against the bark.
