Endangered Moths Invade Sydney Homes
27 Sep
Summary
- Endangered bogong moths are swarming Sydney suburbs during their annual migration.
- The moths are crucial food for the endangered mountain pygmy-possum.
- Residents are urged to reduce outdoor lighting to help the moths.

Sydney suburbs and parts of the NSW south coast are experiencing an influx of endangered bogong moths as they make their annual migration south. These insects, travelling from breeding grounds in inland Queensland, NSW, and Victoria, are heading to the cooler Australian Alps. While harmless, their presence has been more noticeable this year, with some being drawn off course by bright city lights.
Experts urge residents to leave the moths undisturbed, as they are a critical food source for the endangered mountain pygmy-possum. Conservation concerns are high due to declining bogong moth numbers, linked to drought and climate pressures. Reducing unnecessary outdoor lighting is recommended to aid the moths' journey.
