Abstract
Interannual evolution of a polymorphism for a supernumerary segment in the smallest autosome of the grasshopper Eyprepocnemis plorans has be en analysed in two natural populations. The polymorphism seemed to be stable in both populations, despite its undertransmission through hete rozygous females carrying B chromosomes. Analyses of the effects of th e extra segment on mating behaviour failed to show differential mating success in any sex or consistent effects on mating pattern. These res ults are discussed in relation to the maintenance of this polymorphism in natural populations.
