%X During some years the underground grass caterpillar, Oncopera fasciculata (Walker), appears in large numbers and causes severe damage to improved pastures in the lower south-east of South Australia and the Central and Western Districts of Victoria. The present paper, which is the first of several, includes a description of the area of study and an account of field observations on the components of the environment that may influence the survivaI rate of the species.
