James Kamstra’s annual summary of Ontario’s butterfly counts, a short note on Courtship Behavior in the Red-disked Alpine, Erebia discoidalis, by Ellen Riggins, a description of observed lek behavior by Silvery Blue, Glaucopsyche lygdamus, by Ralph Thorpe, and notable observations from the Bath area by Dave Edwards and John Hall are also included. It has been about 10 years since moth records have been included in the summary. Although moth records are occasionally submitted to the TEA, there has been no one available to compile and write up a summary on these records. This year Christian Schmidt, Ross Layberry and Alan Macnaughton, have compiled a summary of noteworthy moth observations for the summary. Christian is an Entomologist with the Canadian National Collection of Insects, Arachnids and Nematodes and a member of the Committee on the Status of Endangered Wildlife in Canada`s (COSEWIC) Arthropod Subcommittee. The intent is that Christian will continue to provide summaries of noteworthy observations although we are still seeking out an interested person to compile and report on other common moth records for future summaries. As usual, the articles and notes are followed by the written summary of the 2015 Ontario butterfly records that have been submitted by our many contributors. Data for all records of all butterfly species received for 2015 (much more data than can be included in the printed summary!) are included in a table available to TEA members as PDF files from Ross Layberry (see contact information below). The contents of this publication have been checked for errors and accuracy as much as possible. Please notify us of any corrections of errors or omissions, and these will be included in future issues of Ontario Lepidoptera and incorporated into the database. Pages 95 to 98 show the correspondence between the plant names used in this publication and those in VASCAN – the Database of Vascular Plants of Canada. This is a comprehensive list of all vascular plants reported in Canada, Greenland (Denmark) and Saint Pierre and Miquelon (France). VASCAN is widely accepted by botanists as the current authority for Canadian botanical taxonomy: http://data.canadensys.net/vascan/search We will be accepting records, articles, notes, and photographs for Ontario Lepidoptera 2016 until December 31, 2016. Information on how to submit records can be obtained from the compilers.

    The Historical Development of Agricultural Policy and Urban Planning in Southern Ontario

    Settlement, Food Lands, and Sustainable Habitation: The Historical Development of Agricultural Policy and Urban Planning in Southern Ontario By: Joel Fridman A thesis submitted in conformity with the requirements for the degree of Masters of Arts in Geography, Collaborative Program in Environmental Studies Department of Geography and Program in Planning University of Toronto © Copyright by Joel Fridman 2014 Settlement, Food Lands, and Sustainable Habitation: The Historical Development of Agricultural Policy and Urban Planning in Southern Ontario Joel Fridman Masters of Arts in Geography, Collaborative Program in Environmental Studies Department of Geography and Program in Planning University of Toronto 2014 Abstract In this thesis I recount the historical relationship between settlement and food lands in Southern Ontario. Informed by landscape and food regime theory, I use a landscape approach to interpret the history of this relationship to deepen our understanding of a pertinent, and historically specific problem of land access for sustainable farming. This thesis presents entrenched barriers to landscape renewal as institutional legacies of various layers of history. It argues that at the moment and for the last century Southern Ontario has had two different, parallel sets of determinants for land use operating on the same landscape in the form of agricultural policy and urban planning. To the extent that they are not purposefully coordinated, not just with each other but with the social and ecological foundations of our habitation, this is at the root of the problem of land access for sustainable farming. ii Acknowledgements This thesis is accomplished with the help and support of many. I would like to thank my supervisor, Professor Harriet Friedmann, for kindly encouraging me in the right direction.

A variety of collecting methods was used, including netting, light attracting, light trapping and pheromone trapping. The specimens were identified by the currently available pictorial sources and determination keys. Many were also sent to specialists for confirmation or identification. The majority of the data was from Kanawha County, reflecting the area of more intensive sampling effort by the senior author. This imbalance of data between Kanawha County and other counties should even out with further sampling of the area. Key Words: Appalachian Mountains,
  • Insect Survey of Four Longleaf Pine Preserves

    Insect Survey of Four Longleaf Pine Preserves

    A SURVEY OF THE MOTHS, BUTTERFLIES, AND GRASSHOPPERS OF FOUR NATURE CONSERVANCY PRESERVES IN SOUTHEASTERN NORTH CAROLINA Stephen P. Hall and Dale F. Schweitzer November 15, 1993 ABSTRACT Moths, butterflies, and grasshoppers were surveyed within four longleaf pine preserves owned by the North Carolina Nature Conservancy during the growing season of 1991 and 1992. Over 7,000 specimens (either collected or seen in the field) were identified, representing 512 different species and 28 families. Forty-one of these we consider to be distinctive of the two fire- maintained communities principally under investigation, the longleaf pine savannas and flatwoods. An additional 14 species we consider distinctive of the pocosins that occur in close association with the savannas and flatwoods. Twenty nine species appear to be rare enough to be included on the list of elements monitored by the North Carolina Natural Heritage Program (eight others in this category have been reported from one of these sites, the Green Swamp, but were not observed in this study). Two of the moths collected, Spartiniphaga carterae and Agrotis buchholzi, are currently candidates for federal listing as Threatened or Endangered species. Another species, Hemipachnobia s. subporphyrea, appears to be endemic to North Carolina and should also be considered for federal candidate status. With few exceptions, even the species that seem to be most closely associated with savannas and flatwoods show few direct defenses against fire, the primary force responsible for maintaining these communities. Instead, the majority of these insects probably survive within this region due to their ability to rapidly re-colonize recently burned areas from small, well-dispersed refugia.

    Boyne Valley Provincial Park

    BOYNE VALLEY PROVINCIAL PARK One Malaise trap was deployed at Boyne Valley Provincial Park in 2014 (44.11563, -80.12777, 468m ASL; Figure 1). This trap collected arthropods for twenty weeks from April 28 – September 19, 2014. All 10 Malaise trap samples were processed; every other sample was analyzed using the individual specimen protocol while the second half was analyzed via bulk analysis. A total of 1571 BINs were obtained. Over half the BINs captured were flies (Diptera), followed by bees, ants and wasps (Hymenoptera), moths and butterflies (Lepidoptera), and beetles (Coleoptera; Figure 2). In total, 427 arthropod species were named, representing 29% of the BINs from the site (Appendix 1). All BINs were assigned at least to Figure 1. Malaise trap deployed at Boyne Valley family, and 66.6% were assigned to a genus (Appendix Provincial Park in 2014. 2). Specimens collected from Boyne Valley represent 183 different families and 558 genera. Figure 2. Taxonomy breakdown of BINs captured in the Malaise trap at Boyne Valley. APPENDIX 1.

Kons Jr. Last Update: June 2001 Abstract A systematic check list of 489 species of Lepidoptera collected in the University of Florida Natural Area Teaching Lab is presented, including 464 species in the superfamilies Drepanoidea, Geometroidea, Mimalonoidea, Bombycoidea, Sphingoidea, and Noctuoidea. Taxa recorded in Psychidae, Yponomeutidae, Sesiidae, Cossidae, Zygaenoidea, and Thyrididae are also included. Moth taxa were collected at ultraviolet lights, bait, introduced Bahiagrass (Paspalum notatum), and by netting specimens. A list of taxa recorded feeding on P. notatum is presented. Introduction The University of Florida Natural Area Teaching Laboratory (NATL) contains 40 acres of natural habitats maintained for scientific research, conservation, and teaching purposes. Habitat types present include hammock, upland pine, disturbed open field, cat tail marsh, and shallow pond. An active management plan has been developed for this area, including prescribed burning to restore the upland pine community and establishment of plots to study succession (http://csssrvr.entnem.ufl.edu/~walker/natl.htm). The site is a popular collecting locality for student and scientific collections. The author has done extensive collecting and field work at NATL, and two previous reports have resulted from this work, including: a biodiversity inventory of the butterflies (Lepidoptera: Hesperioidea & Papilionoidea) of NATL (Kons 1999), and an ecological study of Hermeuptychia hermes (F.) and Megisto cymela (Cram.) in NATL habitats (Kons 1998). Other workers have posted NATL check lists for Ichneumonidae, Sphecidae, Tettigoniidae, and Gryllidae (http://csssrvr.entnem.ufl.edu/~walker/insect.htm).
