Swarms of Moths Descend on City
Authorities say the moths are harmless and urge residents to switch off unnecessary outdoor lights so the insects can continue south.
Endangered Bogong moths swarmed Sydney suburbs, including the Hawkesbury and North Shore, as the insects undertook their annual migration toward the Australian Alps.
Strong northwesterly winds and bright city lighting frequently pull Bogong moths off their natural route, causing them to gather around homes and street lights instead of continuing inland.
Bogong Watch project manager Linnea Emneby suggests the large numbers indicate a good year for the species, which remains endangered due to prolonged drought and habitat loss.
Authorities urge residents to switch off unnecessary outdoor lighting, noting that Bogong moths are harmless and will be gone soon.
Climate change and human development pose long-term threats to Bogong moths' survival, as rising temperatures make alpine summer habitats increasingly uninhabitable for the species.
