A SYNOPSIS OF OBSERVATIONS ON THE BIOLOGY OF THE AUSTRALIAN BUSHFLY (MUSCA VETUSTISSIMA WALKER)

Abstract
Observations on the biology of the egg, larval, pupal and adult stages of the bushfly are presented. Many major physiological and behavioural responses and the survival of individuals seem to depend on the temperature and moisture conditions of the environment, and on the quality of animal dung available as food for the larvae. The seasonal distribution of bushfly in Australia seems to be determined directly by this dependence. Temporarily unfavourable areas are apparently repopulated by long distance displacement of adults. No diapausing or other stage resistant to adverse conditions, is known.
