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"). During its larval stage, the moth strictly consumes its host plant, poison hemlock, and can exist at hundreds of larvae per individual host plant, destroying large swathes of the hemlock. Not all biological control agents are directed at
Sky-blue poison frog Sky-blue poison frog The sky-blue poison frog ("Hyloxalus azureiventris") is a species of poison dart frog. It is endemic to Peru and known from the lower eastern versant of the Andes in the upper Amazon basin of the San Martín Region. The species has been placed in numerous genera, including the new genus "Cryptophyllobates" erected for it. However, it is now placed in "Hyloxalus"; although "Hyloxalus azureiventris" represents a distinct clade within "Hyloxalus", recognizing it formally would render the rest of "Hyloxalus" paraphyletic. Its main distinguishing feature is dorsolateral stripes that run down the back and end on the posterior.
