The number of aestivating adults of Coccinella septempunctata bruckii was investigated in several kinds of plant communities in the grassland on the bed of the Yodo River in the Osaka Plain, Japan. More adults aestivated in the Miscanthus sacchariflorus community than in Solidago altissima and other plant communities. The temperature in the M. sacchariflorus community was lower than in the S. altissima. In the M. sacchariflorus community more adults tended to be found in the plot with the lowest temperature, indicating that adults of C. septempunctata bruckii might prefer a low temperature site for aestivating.
