Predicted predator search rate models for Chironomus spp (green) and C. dipterum (red) in (a) Toledo, (b) Porto and (c) Evora. Curves are derived from Eq. (5) (sessile prey strategy) for Chisonomus spp and Eq. (4) (active capture strategy) for C. dipterum. Search rates for Chironomus spp are higher than for C. dipterum, especially at higher temperatures. Strategies correspond to the most biologically relevant model for the interacting pair, based on observations of insect movement in nature. Coloured rectangular areas correspond to the range of recorded temperatures (operational temperature range) of the sites (see Supplementary Fig. 1).
