Bogong moths use the Earth's magnetic field to get their bearings on long distance migrations

Each Spring, bogong moths emerge from beneath the soil of south-eastern Australia's plains and take to the air on the first leg of their annual migration, after spending the winter gorging themselves on plant roots to fuel up.

For a long time, scientists wondered how these moths just a few centimetres long made the incredible migration of over 1,000 kilometres to alpine caves in New South Wales and Victoria, and then back to their birthplace, to mate and reproduce in winter.
