The winter distributions of a range of polyphagous predators were investigated in relation to field boundary structure. The distribution of Demetrias atricapillus was significantly positively correlated with the density of cocksfoot (Dactylis glomerata) tussocks, and Forficula auricularia and Tachyporus chrysomelinus were significantly positively correlated with percentage cover of deciduous leaf litter, However, although densities of predators varied significantly between field boundaries, no further relationships were identified to explain the observed predator distribution patterns. It is suggested that detailed intensive investigations rather than the extensive approaches of the present study, are required to address questions relating to successful over wintering and selection of over wintering site.
