Abstract
DURING studies of wing length and diapause of Gerris odontogaster (Zett.) (Heteroptera, Gerridae), I claimed1 an intimate correlation between the micropterous and nondiapause conditions and the macropterous and diapause conditions respectively, in pre-overwintering populations. I also summarised the general determination of wing lengths and diapause (Fig. 1), and later a macropter with fully developed eggs was collected from a dimorphic population.
