  • Checklist of the spiders (Araneae) of British Columbia

      Pages: 25 - 52
      Abstract: In 2006, Royal British Columbia Museum (RBCM; Victoria, British Columbia) researchers began systematically documenting the full diversity of British Columbia’s spider fauna. Initially, museum specimens and literature records were used to update an existing checklist and identify poorly sampled habitats in British Columbia. Annual field surveys of spiders, primarily targeting alpine and subalpine habitats, began in 2008; barcode identification of previously unidentifiable specimens commenced in 2012. These efforts have resulted in significant increases in the area of British Columbia that has been sampled for spiders, the number of species documented in the British Columbia checklist, and the number of specimens in the RBCM collection. Many of the additions to the checklist represent the first Canadian or Nearctic records of those taxa or are undescribed species. The number of species recorded in British Columbia has climbed from 212 in 1967 to 902 in 2021. Here, we present distributions for those taxa by ecoprovince and highlight the need for additional sampling efforts. The lack of conservation concern regarding spiders relative to other taxa is notable, particularly in light of the fact that more than 40% (357) of the native species of spiders in the province are represented by five or fewer collection records. The progress of the RBCM’s work has made the institution an important repository of western Nearctic spiders and shows that British Columbia is an important area of Nearctic spider diversity.

  • A northern range extension of a Canadian species of Special Concern,
           Dielis pilipes (Hymenoptera: Scoliidae), in the Okanagan Valley of British

    • Authors: T.D. Nelson, C.E. Moffat
      Pages: 82 - 86
      Abstract: The only known Canadian records of the yellow scarab hunter wasp, Dielis pilipes (Saussure) (Hymenoptera: Scoliidae), are from the southern Okanagan and Similkameen valleys of British Columbia. We report a 25-km northern range extension of the species into the Ponderosa Pine Biogeoclimatic Ecosystem Classification zone, collected in an unmanaged agricultural field in Summerland, British Columbia. This finding is of conservation importance and has implications for natural biological control of ten-lined June beetles, Polyphylla decemlineata (Say) and P. crinita LeConte (Coleoptera: Scarabaeidae), incidental agricultural pests in the Okanagan.

  • Redescription of the spider Robertus arcticus (Chamberlin & Ivie)
           (Araneae: Theridiidae), with the first description of the female

    • Authors: J. Pinzon, K. Kent, D.J. Buckle, R. Bennett
      Pages: 3 - 11
      Abstract: The original description of Robertus arcticus (Chamberlin and Ivie, 1947) (Araneae: Theridiidae) was based on a single male collected in Alaska, United States of America. The female has remained undescribed, although specimens of both sexes have been collected over the intervening decades. The species occurs in boreal Alaska, and records from Cold Lake, Alberta, Canada and James Bay, Ontario, Canada suggest that it is probably widely distributed in the Canadian boreal. Here we redescribe the male and describe the female for the first time. Most specimens examined in our study were collected from the ground of boreal forest peatlands in northeastern Alberta.

  • Population size estimation for the Warren root collar weevil, Hylobius
           warreni Wood (Coleoptera: Curculionidae), a pest of regenerating lodgepole
           pine plantations

    • Authors: S.L. Balogh, N. Björklund, D.P.W. Huber, B.S. Lindgren
      Pages: 12 - 18
      Abstract: The Warren root collar weevil, Hylobius warreni Wood (Coleoptera: Curculionidae), is an endemic pest species of conifers, particularly lodgepole pine (Pinus contorta var. latifolia) (Pinaceae), in British Columbia. Larvae feed on the roots and root collars of young trees, resulting in girdling damage and mortality or growth reductions. Population sizes of adult H. warreni have historically been difficult to assess due to a lack of operational sampling methods or chemical attractants for the species. Therefore, most previous population estimates have relied on indirect or incomplete measures of damage by immature individuals. In this study, we tested the Björklund funnel trap to assess its efficacy as a method to estimate H. warreni populations. Funnel traps were placed on all 182 trees in half of a small (~1 ha) lodgepole pine stand over four days and remained in place for 13 days after the last traps were installed. Adult weevils were captured, marked, and released on the bole of the tree on which they had been caught. It is likely that most of the adult weevils in the plot, which was isolated from any nearby lodgepole pine stands, were caught at least once and many were caught multiple times. Population sizes were estimated using both the Schnabel method and the Schumacher and Eschmeyer method, resulting in population estimates of 1.83-2.19 weevils/tree and 731-875 weevils/ha. These measures are within the range of population sizes estimated by previous studies. The results suggest the Björklund funnel trap may be an effective operational tool for population monitoring for this species and may also be an effective tactic in population reduction strategies.
