Fig. 2. Graphs plotting the relationship between over-eating one nutrient (protein, P, or carbohydrate, C) and under-eating the other versus food composition, relative to the selected point of intake when insects were provided with a choice of complementary foods (the intake target, IT, from Fig. 1). Data are for intake up to day 5 in the stadium. The theoretical minimum nutritional error (absolute sum of over-eating one nutrient and under-eating the other relative to the intake target) is shown as a dotted line. Note how solitarious insects (A) followed a strategy that minimised the total nutritional error, while gregarious locusts (B) tolerated over-eating the nutrient in excess relative to the intake target (hatched region).
