Biological pest control predatory midge "Feltiella acarisuga", and a ladybird "Stethorus punctillum". The bug "Orius insidiosus" has been successfully used against the two-spotted spider mite and the western flower thrips ("Frankliniella occidentalis"). Predators including "Cactoblastis cactorum" (mentioned above) can also be used to destroy invasive plant species. As another example, the poison hemlock moth ("Agonopterix alstroemeriana)" can be used to control poison hemlock ("Conium maculatum").

Not all biological control agents are directed at
