Millions of bogong moths blanket Australian cities despite endangered status

Millions of bogong moths have been found in Australian cities, with sightings reported in homes, cars, and even bedrooms. These moths are migrating from southern breeding grounds to the cool caves of the Australian Alps.

Despite the large numbers observed, bogong moths remain listed as endangered on the IUCN Red List. Scientists believe this is due to climate change, which is warming the mountain boulderfields where the moths seek refuge.

Researchers are trying to determine why the moth population has increased in cities. Possible factors include more food, favorable breeding conditions, and strong winds carrying moths toward the coast. However, it is unclear if this indicates population recovery or simply more frequent sightings.

Citizen scientists are helping fill knowledge gaps about bogong moths. These observations provide valuable data, such as the moths' preference for certain plants like Callistemons and Grevilleas, which was previously unknown.

The moths' endangered status is based on habitat quality, specifically the cool mountain environments they rely on. As the Australian Alps warm due to climate change, these habitats are becoming less viable for the species, threatening their survival.

Researchers are exploring ways to track bogong moth migration, including using weather radar. Public participation in programs like Bogong Watch is also encouraged to aid in understanding their movement patterns.
