Thousands of bogong moths swarm Sydney and NSW south coast, residents urged not to harm them

Thousands of bogong moths have descended on Sydney and parts of the New South Wales south coast, creating dense swarms that have been observed across residential and public areas. The sudden influx has drawn attention from local authorities and wildlife groups, who are monitoring the situation as the insects move through the region.

Bogong moths (Agrotis infusa) are a native Australian species known for their long-distance seasonal migration from the lowland breeding grounds in the south to the alpine regions of the Australian Alps, where they aestivate during the summer months. The species is listed as endangered, with population declines attributed to habitat loss, climate change, and predation pressures.

The current swarms have been reported in multiple suburbs of Sydney as well as coastal towns along the south coast, with residents describing the moths as filling streets, gardens and outdoor spaces in large numbers. The insects are attracted to lights and can accumulate in significant quantities, especially during the evening hours.

Residents have been advised not to harm the moths, as they are protected under state wildlife legislation. Authorities have urged the public to avoid crushing or killing the insects, and to keep windows and doors closed where possible to reduce indoor incursions. Information on safe ways to manage the presence of the moths, such as gently guiding them outdoors, has been distributed through community channels.

Wildlife officials continue to monitor the migration pattern and the health of the bogong moth population, emphasizing the importance of the species to the broader ecosystem. Ongoing surveys will assess whether the current swarm is part of a typical seasonal movement or indicative of broader environmental changes affecting the endangered moth.
