Rising global temperatures are expected to reshape predator–prey interactions, which central the structure, dynamics and functioning of natural ecosystems. While predator feeding rates known depend on temperature vary across species, how this relationship varies within species different climatic regions conditions they inhabit is still poorly understood. Yet identifying essential predict populations communities will be affected by climate change geographic regions. Here we address knowledge gap experimentally measuring thermal responses predators collected from nine representing three latitudes spanning most continental US (a gradient 11°). Specifically, set up 145 independent replicated systems an experimental ranging 5–35°C quantify response curves for each populations. We found stark differences in clear humped‐shaped a mostly linear increase. Most notably, these intraspecific overall shapes reveal opposing latitudinal patterns depending range considered. These results that local can shape interactions respond warming highlight need consider past when predicting at local, regional, scale.
