Figure 8

The build up and decline of Bogong moth numbers on the roof of Ian Common’s observation cave on Mt Gingera over the summer of 1952–1953. Each panel shows the area of the cave roof monitored and the black areas are the areas covered by Bogong moths. Numbers became maximal at New Year and then slowly declined until the beginning of March, with moths gradually disappearing first from the more exposed parts of the cave near its entrance (E). Note the upswing in moth numbers from mid to late March—moths migrating from further south were apparently using this cave as a temporary shelter during their northward journey. Dotted lines show the width and length of the trench Common dug to assist entry to the cave. Scale bar = 2 m. Reproduced from Common (1954), with permission from CSIRO Publishing.
