Bogong Moth Migration — Australian Alps

About this spectacle

Each spring, billions of bogong moths rise from the warming lowland plains and stream southward toward the cool granite caves and boulder fields of the Snowy Mountains. Arriving in such density that they can visibly darken the sky, the moths cluster in wall-to-wall carpets across cave ceilings and rock outcrops to aestivate through the heat. Standing near a moth-filled cave, visitors experience an almost surreal sensation: wings rustling in waves, the faint earthy smell of congregated insects, and a visual texture of living, shifting grey-brown fur across every surface. At peak arrival, clouds of moths swirl at dusk against the alpine silhouette. The high country terrain — boulder slopes, sub-alpine meadows, and granite tors — provides the backdrop. The migration is ecologically significant, representing one of the most dramatic insect mass-movement events in Australia, historically drawing Aboriginal communities to the mountains for ceremonial gatherings and feasting on the fat-rich moths.
