Do Butterflies Use “Hearing Aids”? Investigating the Structure and Function of Inflated Wing Veins in Nymphalidae Do butterflies use “hearing aids”? Investigating the structure and function of inflated wing veins in Nymphalidae by Penghui (Carrie) Sun A thesis submitted to the Faculty of Graduate and Postdoctoral Affairs in partial fulfillment of the requirements for the degree of Master of Biology in Biology Carleton University Ottawa, Ontario © 2018 Penghui (Carrie) Sun Abstract Many butterfly species within the subfamily Satyrinae (Nymphalidae) have been informally reported to possess a conspicuous “inflated” or “swollen” subcostal vein on each forewing. However, the function and taxonomic diversity of these structures is unknown. This thesis comprises both experimental and comparative approaches to test hypotheses on the function and evolution of these inflated veins. A laser vibrometry study showed that ears in the common wood nymph, Cercyonis pegala, are tuned to sounds between 1-5 kHz and the inflated subcostal vein enhances sensitivity to these sounds. A comparative study showed that all species with inflated veins possess ears, but not all species with ears possess inflated veins. Further, inflated veins were better developed in smaller butterflies. This thesis provides the first evidence for the function of inflated wing veins in butterflies and supports the hypothesis that they function as aids to low frequency hearing. ii Acknowledgements I thank my supervisor Dr. Jayne Yack for the continued guidance and support, throughout my academic program and in beginning my career, as well as an inspired and newfound appreciation I never knew I could have for insects.

  • Wild Species 2010 the GENERAL STATUS of SPECIES in CANADA
    Wild Species 2010 THE GENERAL STATUS OF SPECIES IN CANADA Canadian Endangered Species Conservation Council National General Status Working Group This report is a product from the collaboration of all provincial and territorial governments in Canada, and of the federal government. Canadian Endangered Species Conservation Council (CESCC). 2011. Wild Species 2010: The General Status of Species in Canada. National General Status Working Group: 302 pp. Available in French under title: Espèces sauvages 2010: La situation générale des espèces au Canada. ii Abstract Wild Species 2010 is the third report of the series after 2000 and 2005. The aim of the Wild Species series is to provide an overview on which species occur in Canada, in which provinces, territories or ocean regions they occur, and what is their status. Each species assessed in this report received a rank among the following categories: Extinct (0.2), Extirpated (0.1), At Risk (1), May Be At Risk (2), Sensitive (3), Secure (4), Undetermined (5), Not Assessed (6), Exotic (7) or Accidental (8). In the 2010 report, 11 950 species were assessed. Many taxonomic groups that were first assessed in the previous Wild Species reports were reassessed, such as vascular plants, freshwater mussels, odonates, butterflies, crayfishes, amphibians, reptiles, birds and mammals. Other taxonomic groups are assessed for the first time in the Wild Species 2010 report, namely lichens, mosses, spiders, predaceous diving beetles, ground beetles (including the reassessment of tiger beetles), lady beetles, bumblebees, black flies, horse flies, mosquitoes, and some selected macromoths. The overall results of this report show that the majority of Canada’s wild species are ranked Secure.

  • Some Butterfly Observations in the Karaganda Oblast of Kazakstan (Lepidoptera, Rhopalocera) by Bent Kjeldgaard Larsen Received 3.111.2003
    ©Ges. zur Förderung d. Erforschung von Insektenwanderungen e.V. München, download unter www.zobodat.at Atalanta (August 2003) 34(1/2): 153-165, colour plates Xl-XIVa, Wurzburg, ISSN 0171-0079 Some butterfly observations in the Karaganda Oblast of Kazakstan (Lepidoptera, Rhopalocera) by Bent Kjeldgaard Larsen received 3.111.2003 Abstract: Unlike the Ural Mountains, the Altai, and the Tien Shan, the steppe region of Cen­ tral Asia has been poorly investigated with respect to butterflies - distribution maps of the re­ gion's species (1994) show only a handful occurring within a 300 km radius of Karaganda in Central Kazakstan. It is therefore not surprising that approaching 100 additional species were discovered in the Karaganda Oblast during collecting in 1997, 2001 and 2002. During two days of collecting west of the Balkash Lake in May 1997, nine species were identified. On the steppes in the Kazakh Highland, 30 to 130 km south of Karaganda, about 50 butterflies were identified in 2001 and 2002, while in the Karkaralinsk forest, 200 km east of Karaganda, about 70 were encountered. Many of these insects are also to be found in western Europe and almost all of those noted at Karkaralinsk and on the steppes occur in South-Western Siberia. Observations revealed Zegris eupheme to be penetrating the area from the west and Chazara heydenreichi from the south. However, on the western side of Balkash Lake the picture ap­ peared to change. Many of the butterflies found here in 1997 - Parnassius apollonius, Zegris pyrothoe, Polyommatus miris, Plebeius christophi and Lyela myops - mainly came from the south, these belonging to the semi-desert and steppe fauna of Southern Kazakstan.

  • Taxonomy, Distribution and Biology of the Genus Cercyonis (Satyridae)
    1969 Journal of the Lepidopterists' Society 165 TAXONOMY, DISTRIBUTION AND BIOLOGY OF THE GENUS CERCYONIS (SATYRIDAE). 1. CHARACTERISTICS OF THE GENUS THOMAS C. EMMEL Department of Zoology, The University of Florida, Gainesville Evolution of butterflies in the satyrid genus Cercyonis has produced a complex of species groups and variable populations in North America that has not been reviewed thoroughly since the last century. The pur­ pose of this paper and others to follow in the series is to provide a critical, modern synthesis of taxonomic, distributional and biological information on all species and subspecies within the genus, based on extensive studies by the author from 1960 to the present. In future papers, each species group will be treated intensively, with plates of both sexes of adults of all subspecies, larvae, pupae, figures of eggs, genitalia, androconia, antennae and other important morphological characters, and chromosomes. Genetic data and hyblidization crosses will also be summarized in the present series from mateIial to be pub­ lished in full elsewhere. TAXONOMY The Nearctic genus Cercyonis has had over thirty specific, subspecif'ic, or varietal names applied to it, and no taxonomic revision has been at­ tempted since the 1880s (Edwards, 1880). On the basis of extensive field work, examination of over 5,000 adult C ercyonis specimens, rearing of many of the named forms, and studies of external and internal morphology of all these forms, the following new taxonomic treatment is proposed.l 1. Cercyonis sthenele (Boisduval, 1852) a. sthenele sthenele (Boisduval, 1852) b. sthenele silvestris (Edwards, 1861) c. sthenele paulus (Edwards, 1879) behrii (Grinnell, 19(5) d.

  • 2010 Animal Species of Concern
    MONTANA NATURAL HERITAGE PROGRAM Animal Species of Concern Species List Last Updated 08/05/2010 219 Species of Concern 86 Potential Species of Concern All Records (no filtering) A program of the University of Montana and Natural Resource Information Systems, Montana State Library Introduction The Montana Natural Heritage Program (MTNHP) serves as the state's information source for animals, plants, and plant communities with a focus on species and communities that are rare, threatened, and/or have declining trends and as a result are at risk or potentially at risk of extirpation in Montana. This report on Montana Animal Species of Concern is produced jointly by the Montana Natural Heritage Program (MTNHP) and Montana Department of Fish, Wildlife, and Parks (MFWP). Montana Animal Species of Concern are native Montana animals that are considered to be "at risk" due to declining population trends, threats to their habitats, and/or restricted distribution. Also included in this report are Potential Animal Species of Concern -- animals for which current, often limited, information suggests potential vulnerability or for which additional data are needed before an accurate status assessment can be made. Over the last 200 years, 5 species with historic breeding ranges in Montana have been extirpated from the state; Woodland Caribou (Rangifer tarandus), Greater Prairie-Chicken (Tympanuchus cupido), Passenger Pigeon (Ectopistes migratorius), Pilose Crayfish (Pacifastacus gambelii), and Rocky Mountain Locust (Melanoplus spretus). Designation as a Montana Animal Species of Concern or Potential Animal Species of Concern is not a statutory or regulatory classification. Instead, these designations provide a basis for resource managers and decision-makers to make proactive decisions regarding species conservation and data collection priorities in order to avoid additional extirpations.
