While open sand habitats are rare in the province, and declining in quality, suitable habitat still remains. However, surveys to verify occurrences since the last record in 1953 have been too infrequent and are insufficient to draw any conclusions about extent of occurrence, population size, threats, or trends. Occurrence British Columbia Status history Species considered in April 2017 and placed in the Data Deficient category. iii COSEWIC Executive Summary Columbia Dune Moth Copablepharon absidum Wildlife Species Description and Significance The Columbia Dune Moth, Copablepharon absidum, is a medium-sized moth (forewing length 16–19 mm) in the family Noctuidae. The forewings are yellow or yellow- orange, often with olive-grey shading, and two slightly paler streaks along its wings. The Columbia Dune Moth is closely associated with sparsely vegetated sandy habitats in the driest and warmest regions of Canada. It is one of several focal species representing the sensitivity and uniqueness of this habitat type in Canada. Distribution The global range of the Columbia Dune Moth is from southern British Columbia (BC), south to the United States through the arid interior of Washington to southern Oregon, and east into Idaho. In Canada, the moth is known from three localities, all in BC and separated by large distances of unsuitable habitat: Lillooet (collected once in 1916), Kaslo (collected once in 1923), and Osoyoos (numerous specimens collected in 1953). Habitat The Columbia Dune Moth is primarily associated with open and arid sparsely vegetated, sandy habitats including low elevation Antelope-brush and Sagebrush steppe, sandy grasslands, and dunes. In BC, these habitats are often adjacent to rivers or lakes that experience periodic sand accretion and deposition thereby maintaining open sandy habitat with few trees. Biology Little is known about the biology of the Columbia Dune Moth. There have been no observations of mating, egg laying, larval development, or pupation in Canada. However, sampling records elsewhere in the species’ range indicate it is bivoltine and adults fly from late April to early June and again from late July to early October. Dispersal abilities have not been assessed, but there is no information that indicates it migrates. iv Columbia Dune Moth does not rely on a specific host plant for its life cycle. Collections in Washington State have recorded larvae in sand beneath an unidentified sand-verbena plant, grass, and a trailing legume. Captive-bred larvae complete development and emerge as adults after a one-month pupal stage. Early instar larvae also overwinter, similar to other moths in the Copablepharon genus. Population Sizes and Trends There is no quantitative information on population sizes and trends for the Columbia Dune Moth in Canada or elsewhere in the species’ global range. Loss of sandy habitat at Osoyoos and Lillooet combined with more widespread changes to arid habitats throughout its range suggests that subpopulations, if present, have also potentially declined. The Kaslo specimen was collected prior to the installation of the Corra Linn Dam on Kootenay Lake, which flooded natural sandy habitats at the lakeshore. Repeated sampling has failed to detect the Columbia Dune Moth at or near historical population sites. The closest known population in the United States is near Brewster, Washington, approximately 106 km south of the historical locality at Osoyoos. The possibility of recolonization over this distance is unlikely, although further sampling in the intervening area is required. Surveys to verify occurrences since the last record in 1953 have been too infrequent and are insufficient to draw any conclusions about extent of occurrence, population size, threats, or trends. Threats and Limiting Factors Development activities that result in direct loss of sandy habitat are a threat to the Columbia Dune Moth. This includes the conversion of open natural sandy habitats to agriculture, predominantly vineyards. Conversion or decline in habitat quality may also occur through other activities such as urban housing and commercial development, off-road vehicle use, livestock ranching, and natural system modifications. The Columbia Dune Moth in Canada may be at risk from demographic collapse; subpopulations are spatially isolated and may have increased risk of extirpation. Demographic collapse is considered a limiting factor that exacerbates the effects of other threats. Protection, Status and Ranks Columbia Dune Moth is not protected in any jurisdiction in Canada. The BC Conservation Data Centre has assigned the species the conservation status rank of SH (historical). v TECHNICAL SUMMARY Copablepharon absidum Columbia Dune Moth Noctuelle jaune du bassin Columbia Range of occurrence in Canada: British Columbia Demographic Information Generation time 4-8 months assuming Canadian population to be bivoltine.

  • Recovery Strategy for Sand Verbena Moth (Copablepharon Fuscum)
    British Columbia Recovery Strategy Series Recovery Strategy for Sand-verbena Moth (Copablepharon fuscum) in British Columbia Prepared by the British Columbia Invertebrates Recovery Team March 2008 DRAFT About the British Columbia Recovery Strategy Series This series presents the recovery strategies that are prepared as advice to the Province of British Columbia on the general strategic approach required to recover species at risk. The Province prepares recovery strategies to meet its commitments to recover species at risk under the Accord for the Protection of Species at Risk in Canada, and the Canada – British Columbia Agreement on Species at Risk. What is recovery? Species at risk recovery is the process by which the decline of an endangered, threatened, or extirpated species is arrested or reversed, and threats are removed or reduced to improve the li kelihood of a species’ persistence in the wild. What is a recovery strategy? A recovery strategy represents the best available scientific knowledge on what is required to achieve recovery of a species or ecosystem. A recovery strategy outlines what is and what is not known about a species or ecosystem; it also identifies threats to the species or ecosystem, and what should be done to mitigate those threats. Recovery strategies set recovery goals and objectives, and recommend approaches to recover the species or ecosystem. Recovery strategies are usually prepared by a recovery team with members from agencies responsible for the management of the species or ecosystem, experts from other agencies, universities, conservation groups, aboriginal groups, and stakeholder groups as appropriate. What’s next? In most cases, one or more action plan(s) will be developed to define and guide implementation of the recovery strategy.

  • A Summary of Terrestrial and Freshwater Invertebrate Conservation in British Columbia
    A Summary of Terrestrial and Freshwater Invertebrate Conservation in British Columbia JENNIFER HERON Biodiversity Branch, Terrestrial Ecosystem Science Section, British Columbia Ministry of Water, Land and Air Protection, P.O. Box 9338 Stn Prov Govt, Victoria, BC, V8W 9M1, Canada, and University of British Columbia, 2204 Main Mall, Vancouver, BC, V6T 1Z1, Canada, email [email protected] Key Words: invertebrates, gastropods, butterflies, species at risk, conservation, status, Garry oak ecosystems, British Columbia Introduction Invertebrates dominate the world’s ecosystems, and there are immense challenges to addressing their conservation needs. British Columbia (B.C.) has approximately 50,000 invertebrate taxa (Cannings 1992), 40,000 of which are estimated to be insects (Harding 1997). Very little is known about the distribution, abundance, life history, and habitat requirements of most of these animals, and making assessments on a species-by-species basis to determine if a species is at risk is a formidable task. Even for species groups like butterflies, where the distribution information is well documented, host plant specificity and habitat are not completely known. Regardless of these challenges, interest in the field of invertebrate conservation is growing, and filling in the information gaps is rewarding. There is a strong need for expertise and specialization on a local, regional, and provincial scale for all invertebrate groups. Those wishing to carve a specialist niche in the realm of conservation biology should consider becoming involved in invertebrate conservation. The protection of invertebrates at risk has been initiated at both the federal and provincial level. The federal Species at Risk Act (SARA) provides immediate protection for individuals, residences, and critical habitats for those species which occur on federal lands and are listed as Endangered or Threatened by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC).

  • Species Status Assessment for the Sand Verbena Moth (Copablepharon Fuscum)
    Species Status Assessment for the Sand Verbena Moth (Copablepharon fuscum) Version 1.0 2019 U.S. FISH AND WILDLIFE SERVICE EXECUTIVE SUMMARY This document presents the species status assessment (SSA) for the sand verbena moth (Copablepharon fuscum), completed to characterize the species’ overall viability by using the three conservation biology principles of resiliency, redundancy and representation. We identify the species’ ecological requirements for survival and reproduction at the individual, population, and species levels, and describe risk factors influencing the species’ current and future condition. The sand verbena moth is a narrow endemic that primarily occupies nearshore areas around the Salish Sea in southern British Columbia, Canada, and northern Washington in the United States, with the exception being a single detection on the west coast of Vancouver Island, in British Columbia. Since the species was first discovered in 1994, it has been detected at 11 sites; six in Canada and five in the United States. Searches/surveys for sand verbena moth have been inconsistent in frequency, scope, and intensity, and have only provided information on species presence (e.g. positive and negative detections); the limited demographic information available for the species prevents the development of abundance estimates or population trends for the sand verbena moth. Species viability relies on interconnected healthy populations with habitat that provides for feeding, sheltering, and protection from predators, but we don’t have information to confirm dispersal between the disparate detection sites for the sand verbena moth. The sand verbena moth completes its entire life cycle on and around the yellow sand verbena plant (Abronia latifolia).

  • Chapter 13. Insects at Risk in the Prairie Region
    323 Chapter 13 Insects at Risk in the Prairie Region Peter W. Hall, Paul M. Catling, J. Donald Lafontaine Agriculture and Agri-Food Canada, Environmental Health, Biodiversity, Neatby and Saunders Bldgs., C.E.F., Ottawa, Canada K1A 0C6 Abstract. This chapter describes and analyses insects at risk in the Great Plains grasslands in the prairie provinces (Alberta, Saskatchewan, Manitoba) and the Peace River region in British Columbia. Over the last century and a half, most of the native grasslands in this region have been replaced by intensive agricultural production or impacted by livestock, both activities hugely affecting insect populations. In addition to the relicts of grassland, “non-grassland” habitats exist within the region, including dunes, badlands, and riparian areas. These isolated habitats and their specific species, including insects, are an important part of the regional biodiversity. At the national, regional, and provincial levels of government, and among other conservation organizations, a large number of programs and legislation are aimed at protecting species at risk, including insects. These efforts are reviewed in this chapter. Résumé. Le présent chapitre décrit et analyse les espèces d’insectes en péril dans les grandes plaines des provinces des Prairies (Alberta, Saskatchewan, Manitoba) et dans la région de la rivière de la Paix, en Colombie-Britannique. Au cours des 150 dernières années, la plupart des prairies naturelles de cette région ont été remplacées par des zones d’agriculture intensive ou altérées par l’élevage du bétail, et ces changements ont eu un effet considérable sur les populations d’insectes. Outre les vestiges de la prairie naturelle, il existe dans la région d’autres types d’habitats comme les dunes, les bad-lands et les zones riveraines.

  • A Review of the Higher Classification of the Noctuoidea (Lepidoptera) with Special Reference to the Holarctic Fauna
    Esperiana Buchreihe zur Entomologie Bd. 11: 7-92 Schwanfeld, 29. Juni 2005 ISBN 3-938249-01-3 A review of the higher classification of the Noctuoidea (Lepidoptera) with special reference to the Holarctic fauna Michael FIBIGER and J. Donald LAFONTAINE Abstract The higher classification of the Noctuoidea (Oenosandridae, Doidae, Notodontidae, Strepsimanidae, Nolidae, Lymantriidae, Arctiidae, Erebidae, Micronoctuidae, and Noctuidae) is reviewed from the perspective of the classification proposed by KITCHING and RAWLINS (1998). Several taxa are reinstated, described as new, synonymised, or redescribed. Some characters that have been inadequately described, poorly understood, or misinterpreted, are redescribed and discussed. One family, two subfamilies, four tribes, and three subtribes are proposed as new. Available family-group names of Noctuoidea are listed in an appendix. Introduction Since 1991 the authors have worked towards a trans-Atlantic / trans-Beringian understanding or agreement between the two sometimes quite incongruent classifications of the Noctuidae used in North America and Eurasia. The necessity to push this work forward and publish our results to date has been precipitated by the need for a new European check list, for the book series Noctuidae Europaeae, and for use in fascicles in the ”Moths of North America (MONA)” book series in North America. When Hermann HACKER and the senior author decided to publish a new systematic list for the Noctuoidea in Europe, we agreed to write this review paper as a supplement to the European
