Endangered bogong moths swarm Sydney suburbs and NSW south coast during spring migration

Large numbers of endangered bogong moths have been observed across Sydney suburbs and the New South Wales south coast, with swarms clustering around houses, balconies and streetlights. The influx has been reported in places including Hawkesbury, the North Shore and the Sutherland Shire, prompting social-media videos of the insects circling lights. Police and wildlife officials stress the moths are undertaking their regular spring migration from breeding grounds in inland Queensland, NSW and Victoria toward the Australian Alps, where they shelter during the warm months.

Strong winds and urban lighting can divert them into residential areas, leading to calls for residents to switch off unnecessary outdoor lights. Although harmless to humans, the species is a crucial food source for the critically endangered mountain pygmy-possum and helps transport nutrients to alpine ecosystems, making its decline a broader ecological concern.
