| Abstract: | ABSTRACT. Two insects, one holometabolous and one hemimetabolous, are compared and contrasted in respect to feeding efficiency, growth and respiration. An examination of cuticle production in these and other species leads to the conclusion that the nutritional burden of cuticle production in hemimetabolous forms has a significant effect on efficiency, and it is speculated that greater nutritional efficiency in holometabolous forms has been an important evolutionary advantage. |
