Millions of bogong moths are blanketing our cities and they are still endangered

ABC News (Australia)State / PublicCenterNov 4

Citizen scientist Kale Munro documented a massive gathering of bogong moths on the summit of Mount Wills in Victoria, where thousands of insects formed a swirling cloud known as a maelstrom. This significant sighting follows years of population decline, including severe crashes in 2017 and 2019 caused by drought conditions in the moths' lowland breeding areas. Zoos Victoria reported that its Moth Tracker program recorded over 14,000 sightings this year, a substantial increase compared to the previous record of approximately 2,000. Experts attribute the recent recovery to favorable wet seasons that supported larval development, although the species remains classified as endangered due to ongoing threats like climate change. The abundance of moths provides a crucial food source for waking mountain pygmy possums and offers researchers valuable data regarding the species' migration patterns and behavior.

Bogong moths have recently appeared in large numbers in urban areas across eastern Australia, entering homes and vehicles during their annual migration toward the cool caves of the Australian Alps. While this surge offers a hopeful sign for entomologists, the species remains classified as endangered by the International Union for Conservation of Nature due to threats from climate change affecting their mountain habitats. Scientists are investigating whether this increase represents a genuine population recovery or simply higher visibility in cities, noting that factors like favorable breeding conditions and wind patterns may play a role. Unlike birds, whose movements can be modeled, bogong moth migration patterns are less understood, though citizen science efforts are providing valuable data on their behavior and plant preferences. The article highlights the complexity of assessing extinction risk for insects compared to larger, easier-to-count animals, emphasizing that widespread presence does not necessarily indicate a healthy population.

This article discusses a new study exploring the potential of citizen science to aid in the monitoring of microbats, which are difficult to observe due to their nocturnal habits and small size. Researchers analyzed 51 global studies and conducted their own experiment by providing bat detectors to volunteers in Western Australia to record ultrasonic calls. The piece highlights the ecological importance of bats, noting that they constitute roughly 22 percent of all mammal species and play critical roles in pollination and pest control. It addresses persistent misconceptions and negative perceptions surrounding bats, suggesting that direct engagement through citizen science can improve public understanding. The findings indicate that acoustic surveys via volunteer-run detectors are a viable method for gathering data on bat presence and diversity.
