Table 2 The energy content of types and stages of ants in joules/individual and in worker-equivalents. Energy content was calculated from the fat and lean weight of Crematogaster ashmeadi ants, using 18.87 J/mg for lean weight, and 39.33 J/mg for fat. Energetic investment in adult females far exceeds any other. A worker-equivalent value for worker larvae was not calculated because these were mixed instars.
