The effects of flower supplementation on pollinators and pollination along an urbanisation gradient
PLANTS, PEOPLE, PLANET, EarlyView.Enhancing urban greenspaces for pollinator communities by planting flower patches is increasingly common, but their efficacy for different groups of insects (bees, hoverflies and moths) is unclear. Our city‐scale experiment demonstrated that the effect of flower patches on pollinators is complex, and direct benefits to specific insects are difficult to
