still harboured thousands of moths, which suggested that the moths "came from different breeding grounds, where one location wasn't as badly affected by the drought as the other. I don't think they will disappear completely, but there's certainly a possibility that they could become locally extinct at their breeding grounds.", Warrant said. Other biologists and ecologists have pointed to the dramatic effect on animals which feed on the moths, which are an important source of protein for wildlife, including the threatened mountain pygmy possum as well as other insectivorous mammals and birds. "The vulnerability of the Australian Alps to climate change is the worst in the world because we've got these short little mountains so when it gets warmer, there is nowhere for these cold-adapted species to go", according to Euan Ritchie, a wildlife ecologist at Deakin University. Interactions with humans Food source Bogong moths were historically used as a food source by Aboriginal peoples located in South-eastern Australia. Groups would travel to the area towards the summits of mountains to harvest moths, where they also met with other Aboriginal peoples, fostering inter-tribal relations as people gathered and feasted during these harvests. They would go into the caves and scrape aestivating moths off the walls into nets and dishes using sticks. Once gathered, the moths would be roasted to remove the scales and wings and then either eaten immediately or ground into a paste and made into "moth meat" cakes that would last and could be taken home. The moth was said to have a nice nutty flavour that was most similar to walnuts or almonds. The bogong moth is an icon of Australian wildlife due to this historical role as an important food source and as an inter-tribal gathering point in Southeastern Australia. An excavation of Cloggs Cave, near Buchan in Victoria, revealed microscopic remains of moth on a small grinding stone, estimated to be about 2,000 years old. This is the first confirmed evidence of insect food remains discovered on a stone artefact in the whole world. The Gunaikurnai people were one of the peoples who used to travel to the mountains to obtain the high-fat, energy-rich food, and stories of these travels had been passed down in their oral history. The excavation was done by researchers from Monash University in collaboration with the traditional owners, represented by the Gunaikurnai Land and Waters Corporation (GLaWAC). Pest of crop
