Insects were sampled by vacuum.

Survey

Four groups of beetles were represented, weevils and snout beetles (Curculionidae), ground beetles (Carabidae), leaf beetles, flea beetles and rootworms (Chrysomelidae) and seed weevils, (Apionidae). Over 150 species were recorded. These type of beetles (Coleoptera) are extremely important in the diets of farmland birds.

The most common beetle was the Pea & Bean Weevil, Sitona lineatus , which occurred 12 times more commonly than the next commonest beetle, even though most crops were winter wheat or winter oilseed rape. The next most common were Holotrichapion pisi (Apionidae), Bembidion guttula, and Trechus quadristriatus ( ground beetles), Chaetocnema concinna Beet flea beetle, Sirocalodes depressicollis (weevil or snout beetle) and Demetrias atricapillus a ground beetle.

There were 30 beetle species where only a single representative had been found.
