This dataset contains data from a combined field and simulation study regarding spatial pattern formation of nesting, described in the paper: “Batsleer, F., Maes, D., Bonte, D. (2021) Behavioral strategies and the spatial pattern formation of nesting. The American Naturalist”. The study investigates the relative importance of environmental and behavioral mechanisms in nest aggregations of the ground-nesting digger wasp Bembix rostrata. A field study was combined with an individual-based model that simulated the possible behaviors of spatial organisation of nesting. In the first analysis, a ...
