Figure 7. Changes in soluble hexamerin contents in Monarch females (A) and males (B). Short-D adults had been fed daily for four weeks under short day light conditions. Long-D adults had been fed daily for two weeks under short day conditions and for two additional weeks under long day conditions. Contents are expressed as percentages of those in female pupae. Error bars indicate standard errors; when not shown they were too small to be graphed. N = 7 for females and 5 for males. Differences between male and female pupae were not significant (p > 0.2 for all three proteins) as determined by a standard unpaired t-test.
