Saint John's Wort Beetle
The importation in 1944 of Chrysolina quadrigemina and its close relative, C. hyperici, was the first North American attempt at controlling weeds with insects. The insects are natural enemies of Hypericum perforatum, known as Klamath weed in the Western U.S., goat weed in the Mountain States, and, more generally, as St. John's wort.
