Abstract
Adult milkweed beetles (genus Tetraopes) are shown to exhibit geographical variation in the intensity of stabilising selection on body size. This is related in both sexes to inter-locality variation in the amount of intrapopulational variability present in this character. Mean size of female beetles also varies geographically. A model of the selection process is proposed that would select against migration between locally differentiated populations and preserve the partitioning of genetic variation among these populations.
