Table of Contents Proposed Change to Bylaws (P =========================================================================================== Vol. 21, No. 3 August, 2017 =========================================================================================== information about parasitic wasps that use viruses to hijack a host’s behavior. It starts with a parasitic wasp, Dinocampus coccinellae, laying an egg on the abdomen of the ladybug. The parasitic larva hatches and feeds on the lady beetle tissues without any apparent ill-effect to the lady beetle host. After about twenty days, the wasp larva emerges through the ladybug's abdomen without killing it. The D. coccinellae then spins a cocoon between the ladybug's legs, forcing the partially paralyzed ladybug to guard the wasp's cocoon. The mechanism for this forced cocoon guarding is the Dinocampus coccinellae paralysis virus (DcPV). Experiments showed that only about 35% of the guarded D. coccinellae cocoons were eaten by predators, whereas 85- 100% of unprotected cocoons were eaten. Interestingly, about 25% of the lady beetles survive and some even get parasitized a second time. What an amazing connection Why you should go on a MES field day: you never know between these three organisms! The press really liked this what you may find and it does not take any expertise to spot – study and dubbed the beetles 'Zombie Bodyguards'. and collect – something like a lady beetle stuck to a leaf.

MES members Peter Darling, Anna Court and Bob Grobe attended as did many other moth/insect/nature or photography enthusiasts. Roger is an expert insect photographer. His book, Butterflies Up Close was published in 2013 and continues to be widely used. During the early part of the evening, Peter Darling demonstrated how to use the website of The North American Moth Photographers Group at the Entomological Museum of Mississippi State University: (www.mothphotographersgroup.mssuniversity.edu). Pete said it is the best website for digital identification of moths. Pete gave a tutorial on how to use the site.

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
    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.

  • Influence of Habitat and Bat Activity on Moth Community Composition and Seasonal Phenology Across Habitat Types
    INFLUENCE OF HABITAT AND BAT ACTIVITY ON MOTH COMMUNITY COMPOSITION AND SEASONAL PHENOLOGY ACROSS HABITAT TYPES BY MATTHEW SAFFORD THESIS Submitted in partial fulfillment of the requirements for the degree of Master of Science in Entomology in the Graduate College of the University of Illinois at Urbana-Champaign, 2018 Urbana, Illinois Advisor: Assistant Professor Alexandra Harmon-Threatt, Chair and Director of Research ABSTRACT Understanding the factors that influence moth diversity and abundance is important for monitoring moth biodiversity and developing conservation strategies. Studies of moth habitat use have primarily focused on access to host plants used by specific moth species. How vegetation structure influences moth communities within and between habitats and mediates the activity of insectivorous bats is understudied. Previous research into the impact of bat activity on moths has primarily focused on interactions in a single habitat type or a single moth species of interest, leaving a large knowledge gap on how habitat structure and bat activity influence the composition of moth communities across habitat types. I conducted monthly surveys at sites in two habitat types, restoration prairie and forest. Moths were collected using black light bucket traps and identified to species. Bat echolocation calls were recorded using ultrasonic detectors and classified into phonic groups to understand how moth community responds to the presence of these predators. Plant diversity and habitat structure variables, including tree diameter at breast height, ground cover, and vegetation height were measured during summer surveys to document how differences in habitat structure between and within habitats influences moth diversity. I found that moth communities vary significantly between habitat types.

  • Westenhanger Area and Kiln Wood)
    Folkestone and Hythe Birds Tetrad Guide: TR13 I (Westenhanger area and Kiln Wood) One of the more interesting habitats in TR13 I is the lake at Folkestone Racecourse, which holds breeding Tufted Duck, Little Grebe, Great Crested Grebe and Coot, with these being joined by Gadwall and Pochard in winter, whilst White-fronted Goose, Barnacle Goose, Wigeon, Pintail and Goldeneye have also occurred on occasion, generally during cold weather, though the lake is prone to freezing over during prolonged frosts. Snipe can sometimes be found in the ditches by the lake and Reed Buntings breed in the surrounding vegetation, whilst Marsh Harrier and Merlin have been noted overhead. The parkland area around Westenhanger Castle used to hold Spotted Flycatchers but this species has since declined considerably. Black Redstart has been recorded singing from the racecourse buildings and may occasionally breed here. The fields in the Hillhurst Farm area may attract Lapwings and occasionally Golden Plover, whilst when left as stubble in the winter of 2013/14 they held a flock of up to 50 Yellowhammers, together with single Jack Snipe and Corn Bunting, and small numbers of Stock Doves, Sky Larks, Meadow Pipits, Linnets and Reed Buntings. Large numbers of Mediterranean Gulls may be attracted, with a peak count of about 100 in November 2013. Kiln Wood has breeding Buzzard and typical woodland species, including Nuthatch, whilst Woodcock, Siskin and sometimes Lesser Redpoll may winter and the small pond in the wood can attract Mandarin. In May 2009 a singing Wood Warbler was present but was presumably just a migrant.

  • Impacts of Native and Non-Native Plants on Urban Insect Communities: Are Native Plants Better Than Non-Natives?
    Impacts of Native and Non-native plants on Urban Insect Communities: Are Native Plants Better than Non-natives? by Carl Scott Clem A thesis submitted to the Graduate Faculty of Auburn University in partial fulfillment of the requirements for the Degree of Master of Science Auburn, Alabama December 12, 2015 Key Words: native plants, non-native plants, caterpillars, natural enemies, associational interactions, congeneric plants Copyright 2015 by Carl Scott Clem Approved by David Held, Chair, Associate Professor: Department of Entomology and Plant Pathology Charles Ray, Research Fellow: Department of Entomology and Plant Pathology Debbie Folkerts, Assistant Professor: Department of Biological Sciences Robert Boyd, Professor: Department of Biological Sciences Abstract With continued suburban expansion in the southeastern United States, it is increasingly important to understand urbanization and its impacts on sustainability and natural ecosystems. Expansion of suburbia is often coupled with replacement of native plants by alien ornamental plants such as crepe myrtle, Bradford pear, and Japanese maple. Two projects were conducted for this thesis. The purpose of the first project (Chapter 2) was to conduct an analysis of existing larval Lepidoptera and Symphyta hostplant records in the southeastern United States, comparing their species richness on common native and alien woody plants. We found that, in most cases, native plants support more species of eruciform larvae compared to aliens. Alien congener plant species (those in the same genus as native species) supported more species of larvae than alien, non-congeners. Most of the larvae that feed on alien plants are generalist species. However, most of the specialist species feeding on alien plants use congeners of native plants, providing evidence of a spillover, or false spillover, effect.
