NOTES ON THE ECOLOGY OF AN AUSTRALIAN DESERT SPECIES OF CALOM YRMEX (HYMENOPTERA: FORMICIDAE)

Abstract

The ecology of a formicine desert ant, Calomyrmex, was studied in an arid region of southern N.S.W. The patterns of foraging activity are noted and the nest structure is described. A nearest neighbour analysis of nest distribution found the nests to be strongly aggregated into groups. ***Óbservations of fighting behaviour demonstrated that certain groups of nests were compatible, suggesting that colonies are integrated as a social unit. The mandibular gland secretion released by disturbed foragers and guard ants was deep orange in colour while that released by workers tending young within the nest, was often white or yellow.
