Observed prey consumption (mean ± SE) and prey consumption predicted by the substitutive model for heterospecific (<i>MpNt</i>) pairings foraging on different densities of <i>M</i>. <i>persicae</i> nymphs and with (a) and without (b) the presence of a flower.

<p><i>Mp</i> denotes <i>M</i>. <i>pygmaeus</i> and <i>Nt</i> denotes <i>N</i>. <i>tenuis</i>. Asterisks indicate significant differences between the observed and predicted values of consumption (<i>P<0</i>.<i>05</i>).
