Descriptions of New Species with Complete Venation Friedrich W. Gess Albany Museum, Grahamstown, 6140 South Africa; email: [email protected] — Abstract. In this publication, the first of a projected series revising the Afrotropical (essentially southern African) species of the genus Quartinia Ed. Andre, 1884 (Hymenoptera: Vespidae, Masarinae), eleven new species are described. Of these, seven occurring variously in the southern Namib Desert and in its southward extension down the western coast of South Africa, and one occurring on the southern coast of South Africa, have been found nesting in sand-filled snail shells. They are: australis, bonaespei, conchicola, namaqua, namaquettsis, obibensis, and refugicoln. To these species is added vexilhita which is presumed to have the same nesting habits. A key to distinguish these species is given. The other three newly described species, all from Namibia, are: femorata, geigeriae and lamellata.

  • Bees in Urban Landscapes: an Investigation of Habitat Utilization By
    Bees in urban landscapes: An investigation of habitat utilization By Victoria Agatha Wojcik A dissertation submitted in partial satisfaction of the requirements for the degree of Doctor of Philosophy in Environmental Science, Policy, & Management in the Graduate Division of the University of California, Berkeley Committee in charge: Professor Joe R. McBride, Chair Professor Gregory S. Biging Professor Louise A. Mozingo Fall 2009 Bees in urban landscapes: An investigation of habitat utilization © 2009 by Victoria Agatha Wojcik ABSTRACT Bees in urban landscapes: An investigation of habitat utilization by Victoria Agatha Wojcik Doctor of Philosophy in Environmental Science, Policy, & Management University of California, Berkeley Professor Joe R. McBride, Chair Bees are one of the key groups of anthophilies that make use of the floral resources present within urban landscapes. The ecological patterns of bees in cities are under further investigation in this dissertation work in an effort to build knowledge capacity that can be applied to management and conservation. Seasonal occurrence patterns are common among bees and their floral resources in wildland habitats. To investigate the nature of these phenological interactions in cities, bee visitation to a constructed floral resource base in Berkeley, California was monitored in the first year of garden development. The constructed habitat was used by nearly one-third of the locally known bee species. Bees visiting this urban resource displayed distinct patterns of seasonality paralleling those of wildland bees, with some species exhibiting extended seasons. Differential bee visitation patterns are common between individual floral resources. The effective monitoring of bee populations requires an understanding of this variability. To investigate the patterns and trends in urban resource usage, the foraging of the community of bees visiting Tecoma stans resources in three tropical dry forest cities in Costa Rica was studied.

  • Clear Plastic Bags of Bark Mulch Trap and Kill Female Megachile (Hymenoptera: Megachilidae) Searching for Nesting Sites
    JOURNAL OF THE KANSAS ENTOMOLOGICAL SOCIETY 92(4), 2019, pp. 649-654 SHORT COMMUNICATION Clear Plastic Bags of Bark Mulch Trap and Kill Female Megachile (Hymenoptera: Megachilidae) Searching for Nesting Sites Casey M. Delphia1*, Justin B. Runyon2, and Kevin M. O’Neill3 ABSTRACT: In 2017, we found 17 dead females of Megachile frigida Smith in clear plastic bags of com- posted bark mulch in a residential yard in Bozeman, Montana, USA. Females apparently entered bags via small ventilation holes, then became trapped and died. To investigate whether this is a common source of mortality, we deployed unmodified bags of mulch and those fitted with cardboard tubes (as potential nest sites) at three nearby sites in 2018. We found two dead M. frigida females and five completed leaf cells in one of these bags of mulch fitted with cardboard tubes; two male M. frigida emerged from these leaf cells. In 2018, we also discovered three dead female M. frigida and three dead females of a second leafcutter bee species, Megachile gemula Cresson, in clear bags of another type of bark mulch. Both mulches emitted nearly identical blends of volatile organic compounds, suggesting their odors could attract females searching for nesting sites. These findings suggest that more research is needed to determine how common and wide- spread this is for Megachile species that nest in rotting wood and if there are simple solutions to this problem. KEYWORDS: Leafcutter bees, solitary bees, cavity-nesting bees, Apoidea, wild bees, pollinators, Megachile frigida, Megachile gemula The leafcutter bees Megachile frigida Smith, 1853 and Megachile gemula Cresson, 1878 (Megachilidae) are widespread in North America (Mitchell 1960; Michener, 2007; Sheffield et al., 2011).

THE REPRODUCTIVE BIOLOGY OF PROBOSCIDEA LOUISIANICA (MARTYNIACEAE) Thesis Approved: Dean of Graduate College ii PREFACE The reproductive biology of Proboscidea louisianica is investigated with special emphasis on the insect-plant interrelationship. This study included only one flowering season in only a small part of the plant's range. In order to more accurately elucidate the insect-plant interrelationship much more work is needed throughout Proboscidea louisianica's range. I wish to thank Dr. Ronald J. Tyrl, my thesis adviser, for his time and effort throughout my project. Appreciation is also extended to Dr. William A. Drew and Dr. James K. McPherson for advice and criticism throughout the course of this study and during the prepara­ tion of this manuscript. To Dr. Charles D. Michener, at the University of Kansas; Dr. H. E. Milliron, in New Martinsville, West Virginia; and Dr. T. B. Mitchell, at North Carolina State University I extend my appreciation for their time and expertise in identifying the insects collected during this study.

Although these medically important Rickettsia are often transmitted via haematophagous arthropods, other Rickettsia, such as those in the Torix group, appear to reside exclusively in invertebrates and protists with no secondary vertebrate host. Importantly, little is known about the diversity or host range of Torix group Rickettsia.

Many are highly beneficial. Almost all U.S. crops and domesticated animals, many sport fish and aquiculture species, numerous horticultural plants, and most biologicalN control organisms have origins outside the country. A large number of NIS, however, cause significant economic, environmental, and health damage. These harmful species are the focus of this study. The total number of harmful NIS and their cumulative impacts are creating a growing burden for the country. We cannot completely stop the tide of new harmful introductions. Perfect screening, detection, and control are technically impossible and will remain so for the foreseeable future. Nevertheless, the Federal and State policies designed to protect us from the worst species are not safeguarding our national interests in important areas. These conclusions have a number of policy implications. First, the Nation has no real national policy on harmful introductions; the current system is piecemeal, lacking adequate rigor and comprehensiveness. Second, many Federal and State statutes, regulations, and programs are not keeping pace with new and spreading non-indigenous pests.

  • Iconic Bees: 12 Reports on UK Bee Species
    Iconic Bees: 12 reports on UK bee species Bees are vital to the ecology of the UK and provide significant social and economic benefits through crop pollination and maintaining the character of the landscape. Recent years have seen substantial declines in many species of bees within the UK. This report takes a closer look at how 12 ‘iconic’ bee species are faring in each English region, as well as Wales, Northern Ireland and Scotland. Authors Rebecca L. Evans and Simon G. Potts, University of Reading. Photo: © Amelia Collins Contents 1 Summary 2 East England Sea-aster Mining Bee 6 East Midlands Large Garden Bumblebee 10 London Buff-tailed Bumblebee 14 North East Bilberry Bumblebee 18 North West Wall Mason Bee 22 Northern Ireland Northern Colletes 26 Scotland Great Yellow Bumblebee 30 South East England Potter Flower Bee 34 South West England Scabious Bee 38 Wales Large Mason Bee 42 West Midlands Long-horned Bee 46 Yorkshire Tormentil Mining Bee Through collating information on the 12 iconic bee species, common themes have Summary emerged on the causes of decline, and the actions that can be taken to help reverse it. The most pervasive causes of bee species decline are to be found in the way our countryside has changed in the past 60 years. Intensification of grazing regimes, an increase in pesticide use, loss of biodiverse field margins and hedgerows, the trend towards sterile monoculture, insensitive development and the sprawl of towns and cities are the main factors in this. I agree with the need for a comprehensive Bee Action Plan led by the UK Government in order to counteract these causes of decline, as called for by Friends of the Earth.

  • 2017 City of York Biodiversity Action Plan
    CITY OF YORK Local Biodiversity Action Plan 2017 City of York Local Biodiversity Action Plan - Executive Summary What is biodiversity and why is it important? Biodiversity is the variety of all species of plant and animal life on earth, and the places in which they live. Biodiversity has its own intrinsic value but is also provides us with a wide range of essential goods and services such as such as food, fresh water and clean air, natural flood and climate regulation and pollination of crops, but also less obvious services such as benefits to our health and wellbeing and providing a sense of place. We are experiencing global declines in biodiversity, and the goods and services which it provides are consistently undervalued. Efforts to protect and enhance biodiversity need to be significantly increased. The Biodiversity of the City of York The City of York area is a special place not only for its history, buildings and archaeology but also for its wildlife. York Minister is an 800 year old jewel in the historical crown of the city, but we also have our natural gems as well. York supports species and habitats which are of national, regional and local conservation importance including the endangered Tansy Beetle which until 2014 was known only to occur along stretches of the River Ouse around York and Selby; ancient flood meadows of which c.9-10% of the national resource occurs in York; populations of Otters and Water Voles on the River Ouse, River Foss and their tributaries; the country’s most northerly example of extensive lowland heath at Strensall Common; and internationally important populations of wetland birds in the Lower Derwent Valley.
