Maynard Smith & Price (1973) introduced the theory of games to the issue of animal conflict. In the prediction of the theoretical models (e.g. Maynard Smith & Parker 1976; Maynard Smith 1982), size is often a good predictor of resource holding power (RHP) (Parker 1974), leading to prediction that the larger animal of the 2 opponents should win. When 2 contestants differ in fighting ability or RHP, this asymmetry, if perceived by both contestants, should be used to settle contests. Escalated fighting should occur when the difference in size of contestants is small. In 2 species of the coreid bug, Acanthocephala femorata (Mitchell 1980) and Acanthocoris sordidus (Fujisaki 1980, 1981), males fought with each other for access to females. These 2 species have sexually dimorphic hind legs, that is, only males have enlarged hind femora used for male-male combat. These studies showed that male-male combat for females exists, and that territorial males tended to be larger than non-territorial males. The study of Acanthocoris sordidus (Fujisaki 1981) clarified that size was a reliable measure of RHP, and that males evaluate their opponent 's RHP during wrestling. However, the study did not show the relationship between size differences of contestants and the type of male-male aggressive behaviors. In this study I examined the relationship between male-male aggressive behaviors and size differences of the males in the leaf-footed plant bug, Leptoglossus australis, a species in which males have enlarged hind femora but females do not.
