There was different between two differential geographical and environmental condition areas on elytra color expression patterns of the multicolored Asian lady beetles (Harmonia axyridis). Especially, it was investigated that expression rates of melanic patterns (conspicua, spectabilis and axyridis) relatively increased in overwintering populations collected in highly mean temperature and longer cumulative daylength area. In addition, in the same collection site, the seasonal difference had influenced on color patterns of H. axyridis. Although these effects didn't were not observed in the laboratory, environmental conditions such as temperature or cumulative daylength might be factors that gave an effect on color pattern formation.
