Colour morph frequencies were investigated in samples from 15 Philaenus spumarius populations in the western parts of Byelorussia and Ukraine. The three main results of the study are the following: (1) In many populations, breakdown of the barrier inhibiting penetrance of colour allele expression in the male sex, (2) unexpected absence of the allele p pra (for colour morph praeustus ) in Ukraine, and (3) an apparent positive correlation between altitude of habitat and the frequency of the allele p O (for colour morphs quadrimaculatus, albomaculatus and leucophthalmus ). Some indications of a similar positive correlation between altitude and p O frequency were noted in 1966 in populations living in Norway and Finland. It seems that p O is an allele favoured in habitats at high elevations above sea level.
