The univoltine leaf beetle Phyllotreta ochripes (Curtis, 1837b) is native to the Palaearctic Region from Japan to western Europe.This species was previously evaluated as a potential biological control agent against invasive populations of the woodland weed Alliaria petiolata (Bieb.) Cavara & Grande (Brassicaceae) in North America, but rejected because it could harm native and at-risk populations of Brassicaceae.First North American records are presented for Phyllotreta ochripes (Curtis, 1837). Specimens were examined from the USA: Illinois, Maryland, Michigan, Ohio and Pennsylvania. Internet photographs of apparent additional individuals from USA: Indiana, Michigan, Minnesota, Ohio, Pennsylvania, Tennessee, Wisconsin and Canada: Ontario were also examined. DNA barcoding analysis showed high genetic variability and possible cryptic species within European populations of P. ochripes. Diagnostic information is presented to distinguish P. ochripes. from other North American Chrysomelidae and a species distribution model to assess its potential spread in North America is presented.Phyllotreta ochripes breeds on invasive garlic mustard, Alliaria petiolata (Bieb.) Cavara & Grande (Brassicaceae) and also non-native Rorippa amphibia (L.) Besser and other species of Brassicaceae.A species distribution model and the range of its host plant A. petiolata, indicates the most suitable conditions for this species are in humid areas of eastern North America. However, most of the known records of this species were discovered in areas projected to have low suitability. This is likely a consequence of sampling bias towards western Europe and away from the eastern Asian portion of its native range. The United States of America and Canada are now known to be home to 72 or more species of adventive Chrysomelidae.

The univoltine leaf beetle Psylliodes attenuata (Koch, 1803) is a pest of Cannabis and Humulus (Cannabaceae) and native to the Palaearctic Region, known from eastern Asia to western Europe.First North American records are presented for P. attenuata from Canada: Ontario and Québec. Adult beetle feeding damage to hops Humulus lupulus L. (Cannabacaea) plants is recorded from Québec. Diagnostic information is presented to distinguish P. attenuata from other North American Chrysomelidae and a preliminary assessment of its potential to spread in North America is presented. While our climate analysis is limited by a lack of data, it appears P. attenuata is physiologically capable of persisting throughout the range of Humulus in North America.The United States of America and Canada are now known to be home to 71 or more species of adventive Chrysomelidae.

The univoltine leaf beetle Chrysolina fastuosa (Scopoli, 1763) is native to in the Palearctic Region from eastern Siberia to western Europe.First North American records are presented for C. fastuosa (Scopoli, 1763) (Coleoptera, Chrysomelidae, Chrysomelinae), as confirmed by vouchered specimens from Canada: Nova Scotia. Additional citizen science records from USA: Vermont are also discussed. Diagnostic information is presented to distinguish C. fastuosa from other North American Chrysomelidae and a species distribution model to assess its potential spread in North America is presented. This insect is expected to cause some feeding damage to above-ground parts of ornamental and invasive Lamiaceae, especially species of Galeopsis L. The species distribution model and the range of its host plant Galeopsis tetrahit, suggest the north-eastern US and south-eastern Canada, from the Atlantic coast to the west end of Lake Superior provide the most suitable conditions for this species. The United States of America and Canada are now known to be home to 70 or more species of adventive Chrysomelidae.

The aim of this paper is to systematically explore a large collection of documents pertaining to the allegations made in Patrick Tierney's Darkness in El Dorado: How Scientists and Journalists Devastated the Amazon (2002) for lexical patterns that indicate how key terms were used to analyze and report the allegations, thus forming cultural models of the Darkness in El Dorado controversy. The purpose of this paper is not an analysis of the validity of the allegations in Tierney's book or to take sides with any of the stakeholders in the controversy. Rather, by conducting a systematic analysis of terms used to write about the controversy, the variation in the cultural models of various actors (e.g., journalists and anthropologists) is described and compared.
