Not long ago, bogong moths were abundant in the caves of the Australian alps during summer, and in towns and cities like Canberra during their Spring migration. But since 2019, their numbers have crashed by as much as 99.5%. A research project lead by the Taungurung people in collaboration with the University of Melbourne is working to gather much-needed data on these culturally-significant moths - known as deberra in the local language.
