Fig. 1. (A) Change in water content (g) per gram of dry mass (DM). (B) Percentage survival of larvae maintained under 100, 98.2 and 75% relative humidity (RH) conditions for up to 12 days. (C) Comparison of survival at different water contents under desiccating conditions of 75 and 98.2% RH. Least-squares fit plotted using the following equation: y=cln x+b. (D) Change in osmotically active water content (OAW) during exposure to 98.2% RH. (E) Change in body fluid osmotic pressure (bar) and/or osmolality during exposure to 98.2% RH (1 bar=100 kPa). The horizontal line denotes the environmental water potential. 100% RH (closed triangles), 98.2% RH (open squares), 75% RH (closed circles). Values shown are means ± s.e.m. for three replicates of 10 individuals.
