BOGONG MIGRATION
Bogong moths breed on the flatlands (see "Breeding" section) but to escape the summer heat they migrate to the higher country of the Australian Alps which includes the Great Dividing Range and the snowy mountains and high plains of Victoria and N.S.W. (see map) Strong winds can be a problem to the migratory path of these moths and that is why sometimes there are Bogong Moth plagues in the cities of Sydney, Melbourne and Canberra which are situated between the highlands and Australia's eastern seaboard They return to their breeding grounds in early Autumn to mate and lay their eggs. This trip can be up to 3,000 kms in length and a greater % of the moths perish.
