Abstract Land‐use intensification is often associated with a decline in functional diversity, potentially undermining the provision of ecosystem services. However, how changes traits affect processes remains poorly understood. Variation trait values among species community may drive processes. Alternatively, mass ratio hypothesis proposes that dominant local are related to Using data from 159 farms six European countries, we quantified impact and landscape‐level land‐use intensity on ground beetles as pest control agents. We then assessed extent which diversity community‐weighted mean relate cereal yield. In addition, responses land use effects different yield varied their compare relative studied. Functional improved aphid removal, but did not translate into higher crop yields. Pest aphids was enhanced by proportion smaller, mobile preference for vegetation layer. Smaller, predatory communities The magnitude were more strongly influenced body size than other traits. Our study provides evidence reduced management can improve supporting small‐sized, macropterous beetles. contrast claims ecological intensification, our joint analysis direct indirect via suggests services cannot compensate gap due reduction intensity.
