a, A male Bogong moth. Scale bar, 5 mm. Photo: A. Narendra, from ref. 2. b, Adult moths migrate from their breeding grounds in various regions of southeast Australia to the Australian Alps during spring (green arrows), where they aestivate in cool alpine caves over summer, and return to the breeding grounds in autumn (purple arrows). At the breeding grounds, they mate, lay eggs and die. Immature stages develop underground during the winter. The red dot indicates the experimental site at Adaminaby. Scale bar, 500 km. c, Around 16,000 moths per m2 aestivate on the walls of specific caves in the Australian Alps for up to 4 months before making the return migration. Inset: close-up image of the moths.
