The provinces of Antwerp and Limburg introduce a rare beetle as natural enemy against the oak processionary caterpillar
At the end of May, a group of forest caterpillar hunters (beetle) was moved from the lab to the outdoors. By placing the beetles together with some young oaks and oak processionary caterpillars in a closed, but water and wind-permeable tent, the researchers can determine if the beetles feed on the caterpillars in a more natural environment.
