The known Lepidoptera (moths and butterflies) of the provinces and territories of Canada are summarised, and current knowledge is compared to the state of knowledge in 1979. A total of 5405 species are known to occur in Canada in 81 families, and a further 50 species have been reported but are unconfirmed. This represents an increase of 1348 species since 1979. The DNA barcodes available for Canadian Lepidoptera are also tabulated, based on a dataset of 148,314 specimens corresponding to 5842 distinct clusters. A further yet-undiscovered 1400 species of Lepidoptera are estimated to occur in Canada. The Gelechioidea are the most poorly known major lineage of Lepidoptera in Canada. Nunavut, Prince Edward Island, and British Columbia are thought to show the greatest deficit in our knowledge of Lepidoptera. The unglaciated portions of the Yukon (Beringia), and the Pacific Maritime, Montane Cordillera, and Western Interior Basin ecozones of British Columbia are also identified as hotbeds of undescribed biodiversity.

Indigenous peoples and settlers engaged in innumerable conflicts in the colonies of Vancouver Island and British Columbia between 1849 and 1871. The constant threat of violent Indigenous resistance to settler colonization in the Pacific Northwest—both real and imagined—produced feelings of anxiety for settlers, especially state officials, that shaped colonial strategy and statecraft. To buttress colonial security, the nascent state partnered with Christian missionaries in the hope that missionaries could use education to cultivate the goodwill of Indigenous peoples and train them to accept colonization. The state’s support for early missionary schooling in colonial British Columbia is examined in the context of settler anxieties regarding three instances of Indigenous resistance: a Lekwungen convergence at Fort Victoria in 1851, the Puget Sound War of 1855–56, and the 1864 Tsilhqot'in War. In different ways, settler anxiety over these conflicts acted as a catalyst, prodding the state to support missionary schooling as a financially expeditious way of trying to contain Indigenous resistance and safeguard colonial security. RÉSUMÉ Entre 1849 et 1871, les colonies de l’île de Vancouver et de la Colombie-Britannique sont le lieu d’innombrables con its entre les peuples autochtones et les colons. La menace constante — réelle et imaginaire — d’une résistance violente des Autochtones à la colonisation dans le nord-ouest du Pacifique a engendré un sentiment d’anxiété chez les colons, et en particulier chez les fonctionnaires de l’État, ce qui a façonné la stratégie et la gestion coloniale. Afin de renforcer la sécurité coloniale, l’État naissant s’est associé avec les missionnaires chrétiens dans l’espoir qu’ils utilisent l’éducation afin d’assurer la bienveillance des peuples autochtones et de les amener à accepter la colonisation. Cet article examine le soutien apporté par l’État aux premiers efforts d’enseignement missionnaire en Colombie-Britannique coloniale, dans le contexte des inquiétudes des colons par rapport à trois actes de résistance autochtone : un rassemblement Lekwungen au Fort Victoria en 1851, la guerre du Puget Sound de 1855–1856 et la guerre des Tsilhqot'in de 1864. À maints égards, l’inquiétude des colons alimentée par ces conflits a agi comme un catalyseur, poussant l’État à soutenir l’enseignement missionnaire dans l’espoir d’arriver à contenir la résistance autochtone et à assurer la sécurité coloniale à peu de frais.

Trionychid turtles were widespread throughout much of the Western Interior Basin of North America during the Cretaceous, represented by a wide variety of taxa. Despite their widespread abundance east of the Rocky Mountains, they have not previously been reported from Cretaceous deposits along the Pacific Coast of North America. We report here on an isolated trionychid costal from Vancouver Island, British Columbia. The fossil was recovered from the Late Cretaceous (Turonian to Maastrichtian) Nanaimo Group, on Vancouver Island, British Columbia. While the fossil is generically indeterminate, its presence adds an important datapoint in the biogeographic distribution of Trionychidae.

Rocky Mountain Wood Tick

Tick paralysis continues to be one of the most baffling and fascinating tickborne diseases in Canada. It was first reported in this country by Todd in 1912. Since then about 250 human cases, including 28 deaths, have been recorded from British Columbia. Outbreaks in cattle have affected up to 400 animals at a time, with losses in a herd as high as 65 head. Although the disease is most common in the Pacific northwest, where it is caused by the Rocky Mountain wood tick, Dermacentor andersoni Stiles, it has lately been reported as far south as Florida and has been produced by Dermacentor variabilis Say, Amblyomma maculatum Koch, and A. americanum (L.) (Gregson, 1953). The symptoms include a gradual ascending symmetrical flaccid paralysis. Apparently only man, sheep, cattle, dogs, and buffalo (one known instance) are susceptible, but even these may not necessarily be paralysed.

Conservation Evaluation

In Canada, Dwarf Woolly-heads, Psilocarphus brevissimus var. brevissimus, is restricted to the Similkameen River valley, south of Princeton in southwestern British Columbia and the extreme southeast and southwest corners of Alberta and Saskatchewan, respectively. This paper deals with the three British Columbia populations which represent the northwestern limit of the species which ranges from south-central British Columbia, southward in the western United States to Montana, Idaho, Washington, Oregon, Nevada, Utah, Wyoming, California and Baja California, Mexico. In British Columbia, P. brevissimus is associated with calcareous vernal pools and ephemeral pond edges in large forest openings. This habitat is rare in the area the few existing populations could easily be extirpated or degraded through slight changes in groundwater levels, coalbed methane gas drilling, housing development or recreational vehicles.

Traditionally man has looked to nature to provide cures for diseases. This approach still exists today in the form of ‘bio-prospecting’ for therapeutically-active compounds in venoms. For example, the venoms of many reptiles offer a spectacular laboratory of bioactive molecules, including peptides and proteins. In the last 10–15 years, there have been a number of major proteomic and genomic research breakthroughs on lizard venoms. In this current review, the key findings from these proteomic and genomic studies will be critically discussed and suggestions will be offered for future focused investigations. It is our intention that this article will not only provide a comprehensive picture of the state of current knowledge of the components of lizard venoms, but also engender awareness in readers of the need to protect and conserve such uniquely precious natural resources for several reasons, including the potential benefit of humankind.

I cannot provide a definitive answer to those of us pondering what the best alternative to capitalism is, but after attending the Pacific Northwest Labor History Association (PNLHA) Conference in Westminster, British Columbia, over the weekend of May 28–30, 1999, I can tell you that this is certainly a preferable alternative to standard academic conferences. As usual, the PNLHA was able to produce a cadre of historians (from the trades as well as academia), active unionists, and old-timers whose memories are as tapable as a keg of beer. Although the association designates labor history as its subject, newly elected President Ross Rieder likes to say, “History ends the moment before now.”

Queer moments abound in traditional rituals associated with marriages and weddings, not only in some regions of English Canada but in most European and European-colonised locations. In the Prairie provinces and Ontario, mock weddings (folk dramatic travesties of the Christian/majoritarian wedding ceremony, usually performed cross dressed) can interrupt wedding showers or milestone anniversary parties. And from Prince Edward Island to British Columbia, charivaris (late night visits to a newly married couple, featuring extreme noisemaking and/or traditional trickery) can follow a marriage. The authors question whether these practices transgress against conventional heterosexual marriage or merely ritualise and thus contain potential resistance to its strictures, and find that they do both.

Earthquakes in the past few thousand years have left signs of land-level change, tsunamis, and shaking along the Pacific coast at the Cascadia subduction zone. Sudden lowering of land accounts for many of the buried marsh and forest soils at estuaries between southern British Columbia and northern California. Sand layers on some of these soils imply that tsunamis were triggered by some of the events that lowered the land. Liquefaction features show that inland shaking accompanied sudden coastal subsidence at the Washington-Oregon border about 300 years ago. The combined evidence for subsidence, tsunamis, and shaking shows that earthquakes of magnitude 8 or larger have occurred on the boundary between the overriding North America plate and the downgoing Juan de Fuca and Gorda plates. Intervals between the earthquakes are poorly known because of uncertainties about the number and ages of the earthquakes. Current estimates for individual intervals at specific coastal sites range from a few centuries to about one thousand years.
