Overview about the hatching patterns in relation to the temperature and the used strains (NDP, no diapause; DP, diapause). The width of the rectangles corresponds to the relative proportion of the particular hatching pattern at the same temperature and the length of the rectangles to the proportion of the particular hatching pattern within the same strain. Horizontal dashed lines indicate the absence of the respective pattern. Vertical lines marked in the colour of a certain strain indicate the absence of the respective hatching pattern in this strain. The term ‘normal’ stands for hatching without delay, ‘n’ indicates the number of treatments per strain at the different temperatures
