Amount of faeces produced by individual Nemurella pictetii larvae (final three instars) during 66 hours when kept at low and at high larval density, respectively. Low larval density (1 larva per experimental unit): n = 7 (males), n = 14 (females); high larval density (5 larvae per experimental unit): n = 5 (males), n = 9 (females); the star identifies an extreme value (more than 3 box lengths from the edges of the box), for further explanations of symbols see Figure 3.
