Fig. 2. Comparison of percentage body water content of desiccation-selected flies (D flies) and their controls (C flies) at five phases of development. Values are means of five populations from either the C or D selection treatments ± S.E.M. The asterisk denotes a significant difference between the C and D flies in percentage body water, which was observed only at 4 days post-eclosion (P<0.001).
