Harpalus rufipes

Harpalus rufipes is a species of ground beetle in the subfamily Harpalinae. It was described by Degeer in 1774. Harpalus rufipes is native to Europe. As a predator, Harpalus rufipes is used as a biological agent to control seed-eating pests including aphids and slugs such as Deroceras reticulatum. It has been used as a model organism to investigate the immune system of beetles, and a study has shown it is sensitive to engine oil and diesel oil.
