The aim of this study was to assess the attractiveness of flowers to target groups of beneficial insects. Water trap samples were taken throughout the entire period of inflorescence and were accompanied by sweep net sampling in early summer. Samples were assessed for target insect groups (predatory beetles, true bugs, aphids, hoverflies and Parasitica) that are known to provide ecosystem services in farm landscapes (such as pollination, conservation and pest control). Yarrow and Oxeye daisy were the most promising flowering plants, attracting multiple
beneficial target groups. These species seem to be the most promising for use in flowering field margins.
