Abstract The Palaearctic leaf beetle species Cassida viridis Linnaeus (Coleoptera: Chrysomelidae) is newly recorded from North America on the basis of recent observations of established populations on Monarda Linnaeus (Lamiaceae) plantings in an Ontario, Canada garden. Historical specimen records show that the species has been in Ontario at least since 1974. 
Coleoptera of Canada
TLDR
It is estimated that slightly more than 1000 beetle species remain to be reported from Canada, either as new records or undescribed species, and comparison of BINs to observed species in a group of Canadian Staphylinidae suggests that BIns may provide a good estimate of species diversity within the beetles.

Symbiont Digestive Range Reflects Host Plant Breadth in Herbivorous Beetles
TLDR
The obligate partnership between tortoise leaf beetles and their pectinolytic Stammera symbionts is investigated to detail how changes to the bacterium's streamlined metabolic range can shape the digestive physiology and ecological opportunity of its herbivorous host. Expand
