Nectar-feeding insects, birds and mammals develop complex foraging patterns, such as repetitive multi-destination routes known ‘traplines’. While this behaviour likely influences animals’ success plant mating its drivers prevalence across species environments remain poorly understood. Through a systematic literature review, we show that pollinators display varying degrees of movement repetitiveness. Then, using cognitively realistic agent-based model parametrized with data from bee studies, demonstrate how the interplay between cognition, competition, resource distribution nectar renewal rate can generate various patterns. Our predicts greater repetitiveness when floral resources are scarce spread in space, renews quickly competition is low. These findings challenge assumptions about strict traplining behavioural studies random pollinator movements pollination models. We discuss deeper understanding diversity improve predictions patterns to inform precision agriculture conservation efforts.

ABSTRACT Aim Predicting climate driven species range shifts requires knowledge of mechanisms limiting fitness under various climatic conditions. The traditional approach modelling ranges herbivorous insects by fitting environmental niche models to occurrence records is generally incapable differentiating direct effects on insect populations versus indirect acting the their host plants. Here, we delimit southern extent a major forest defoliator, spruce budworm, Choristoneura fumiferana , in North America, and investigate whether its limited directly or indirectly trees.

Methods We use pheromone traps survey populations; these are sensitive tools for detecting low‐density populations. applied mechanistic effect temperature C. evaluate patterns can be explained climate.
