This non-native beetle was introduced into NA in the mid 1940's from France, to control St. John's wort (also called Klamath Weed), a non-native weed injurious to cattle. It has been introduced to various locales, wherever this plant is found, in eastern and western Canada. And of course, the beetle has also spread (they have wings!). This is the first time I've seen them at FWG, although I have seen them in a number of areas around the Ottawa district. Yet another example of biocontrol at work!
