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
Worse is better Rise of Worse is Better", Gabriel claimed that "Worse-is-Better" is a model of software design and implementation which has the following characteristics (in approximately descending order of importance): Gabriel argued that early Unix and C, developed by Bell Labs, are examples of this design approach. Gabriel contrasted his philosophy with what he called the "MIT/Stanford style of design" or "MIT approach" (also known as "the Right Thing"), which he described as follows. Contrasts are in bold: Gabriel argued that "Worse is better" produced more "successful" software than the MIT approach: As long as the initial program is basically good, it
