Abstract The increasing frequency and intensity of heatwave events in temperate climates threaten to alter behavioural rhythms ectothermic animals, such as insects. However, it is poorly understood how heatwaves affect daily activity patterns insects, whether shaded microclimates can moderate these responses. We investigated the impacts a on diel profile insect activity, comparing effects across open, tree‐covered, hedged habitats. Using yellow pan traps, was monitored from 07:00 AM PM ten non‐consecutive days, including two during heatwave. Insect counts exhibited unimodal relationship with temperature. On open habitat significant (81.9%) reduction compared ‘non‐heatwave’ one before after Smaller, non‐significant reductions were observed tree‐covered (32.3%) (17.8%) rhythm non‐heatwave days approximated relationship, model‐estimated peaking around 03:00 PM; by contrast, bimodal profile, predicted highest morning evening. Such heatwave‐induced deformations patterns, modelled interactions between time day, all three types. findings suggest that markedly decrease levels, whilst shade‐providing vegetational features may reduce this effect, are affected landscape‐wide. As become more frequent, preservation trees hedges landscapes likely crucial support resilience wider ecosystem functioning.
