Bogong moths that usually roam the alpine regions of Victoria and New South Wales have appeared in massive numbers along Australia’s east coast, rattling residents and authorities alike.

The influx, first noticed in Sydney and Canberra in early October, has seen moths invading houses, cars and public infrastructure, prompting widespread media coverage. Scientists point to a combination of climate stress, loss of native habitat and altered wind patterns as possible drivers of the mass migration, while conservationists warn that the species is already listed as endangered.
