Effects of crowding on the frequencies of Patanga japonica last instar nymphs in different black patterning grades in black, yellow-green (Y-green), and white containers. Five nymphs were reared in each container from May 31 to August 15 at room temperature (25.1°C on average). For black patterning grades, see Fig. 1.
