First Observations on Nesting and Immatures of the Bee Genus Ancyla (Apoidea: Apidae: Apinae: Ancylaini)
AMERICAN MUSEUM NOVITATES Number 3749, 24 pp. June 25, 2012 First Observations on Nesting and Immatures of the Bee Genus Ancyla (Apoidea: Apidae: Apinae: Ancylaini) JAKUB STRAKA1 AND JEROME G. RoZEN, JR.2 ABSTRACT Herein we present information on the nest architecture and nesting biology primarily of Ancyla asiatica Friese and, to a lesser extent, of A. anatolica Warncke, both found near Adana, Turkey. These two ground-nesting species visit Apiaceae for mating and larval provisions, with A. asiatica going to Daucus carota and A. anatolica, to Eryngium. The cocoon of A. asiatica is described in detail as are the mature oocytes of both species and the pre- and postdefecating larvae of A. asiatica. Each site was attacked by a separate, unnamed cleptoparasitic species of Ammobates (Nomadinae). The relationships of the Ancylaini to other apine tribes are discussed based on their mature larvae, and a revised tribal key to mature larvae of nonparasitic, noncor- biculate Apinae is presented. INTRODUCTION Of all tribes of nonparasitic Apidae, the natural history of the Ancylaini3 has been the least investigated. Until now, nothing has been recorded concerning the nests of any species, 1 Department of Zoology, Faculty of Science, Charles University in Prague, CZ-12844 Prague 2, Czech Republic. 2 Division of Invertebrate Zoology, American Museum of Natural History. 3 The spelling of tribe Ancylini Michener, 1944, has recently been emended to Ancylaini to remove hom- onymy with Ancylini Rafinsque, 1815 (Mollusca, Gastropoda) (Engel et al., 2010: ICZN Ruling (Opinion 2246-Case 3461).

A Molecular Phylogeny of the Long-Horned Bees in the Genus Melissodes Latreille (Hymenoptera: Apidae: Eucerinae)
Insect Systematics & Evolution (2020) DOI 10.1163/1876312X-bja10015 brill.com/ise A molecular phylogeny of the long-horned bees in the genus Melissodes Latreille (Hymenoptera: Apidae: Eucerinae) Karen W. Wrighta,b,*, Kelly B. Millera and Hojun Songb aDepartment of Biology, University of New Mexico, Albuquerque, NM, USA bDepartment of Entomology, Texas A&M University, College Station, TX, USA *Corresponding author, e-mail: [email protected] Abstract The genus Melissodes Latreille in the subfamily Eucerinae (Hymenoptera: Apidae) is a widespread and common group of bees. There are 129 describedMelissodes species that range throughout the western hemisphere with the center of diversity in the warm deserts of southwestern North America. Despite its widespread nature and importance in agriculture, the evolutionary relationships among the species have never been investigated. Here, we present a molecular phylogeny using five loci for 89 species of Melis- sodes with representatives from all subgenera. We confirm all of the subgeneric delineations constructed by LaBerge, except for a paraphyletic M. (Tachymelissodes) and the placement of M. (Heliomelissodes), which renders M. (Eumelissodes) paraphyletic. We also discuss the unexpected placement of M. tristis Cockerell, M. paucipuncta LaBerge, M. dagosus Cockerell, and M. pexa LaBerge. Finally, we combine this analysis with previous data to support the placement of Melissodes within the subfamily Eucerinae. Keywords Anthophila; Eucerini; bee phylogeny; long-horned bees Introduction The genus Melissodes Latreille (Apidae: Eucerinae sensu Bossert et al. 2019) is a diverse genus of medium sized, setaceous bees. It is the second largest genus in the tribe Eu- cerini with 129 described species ranging from Canada to Argentina. -
Effects of Cultivation and Proximity to Natural Habitat on Ground-Nesting Native Bees in California Sunflower Fields
JOURNAL OF THE KANSAS ENTOMOLOGICAL SOCIETY 79(4), 2006, pp. 309–320 Effects of Cultivation and Proximity to Natural Habitat on Ground-nesting Native Bees in California Sunflower Fields 1 2 3 JOHN KIM, NEAL WILLIAMS, AND CLAIRE KREMEN ABSTRACT: Agricultural conversion is one of the most prevalent anthropogenic uses on the terrestrial earth. Persistence of organisms in such landscapes is thought to be related to species- specific characteristics such as life history traits and dispersal distance. In an agricultural landscape in California, we examined local (farm-level) and landscape variables associated with nesting pref- erences of native ground-nesting bees. Compared to the known ground-nesting visitors to crops, bee community nesting on farms was depauperate. Further, more abundant and diverse communities of bees were found nesting at farms with patches of natural habitat near by than farms that were far away from natural habitat. Species responded differently to soil conditions created by farming practices, but the variability in nesting bee abundance was lower in farms near natural habitat than farms far from natural habitat. These findings suggest that most bee species are affected adversely but to varying degrees by agricultural intensification, and that natural habitats may buffer against the bee population variability in agricultural landscape. We present source/sink dynamics and resource limitations as possible explanations for the observed patterns. KEY WORDS: Ground-nesting bees, sunflower, nesting density, source-sink dynamics, agriculture, biodiversity, pollination Humans have appropriated an estimated 40% of the terrestrial surface for agriculture, greatly modifying the environment and ecosystem processes (Olson et al., 1983; Vitousek et al., 1997; Chapin et al., 2000; DeFries et al., 2004). -
Pollinators and Visitors of the Generalized Food-Deceptive Orchid Dactylorhiza Majalis in North-Eastern Poland

Food-deceptive orchids usually implement a generalized plant pollination strategy and a relatively diverse group of pollinators visit them. Dactylorhiza majalis is a food-deceptive, early-flowering orchid that relies on insect-mediated pollination. This study’s objectives were to identify D. majalis’ pollinators and flower visitors and their foraging behaviors on D. majalis inflorescences. We also assessed the bending movement time to determine the relationship between bending time and the duration of pollinators’ visits. To assess pollination efficiency, we measured the spur length of D. majalis flowers, which is expected to affect the mechanical fit to pollinators/Bpotential^ pollinators. The arthropod fauna were investigated to examine the availability of Bpotential^ pollinators in populations. We identified Apis mellifera as this orchid’s main pollinator and confirmed that few of the flower visitors belonged to Diptera (12 individuals, 9 taxa), Hymenoptera (3 individuals, 3 taxa), or Coleoptera (2 individuals, 2 taxa) in our dataset, which was collected over a 2-year period and includes 360 h of video. The arthropods were collected by a sweep net in D. majalis populations and there were fewer Hymenoptera (2.9–23.2%) and Coleoptera (4.4–23.8%) visitors but more Diptera (23.3–58.6%) visitors. -

DIFFERENTIAL IMPACTS OF POLLEN QUALITY AND MICROBIAL COMMUNITIES ON GENERALIST AND SPECIALIST BEES VISITING A SHARED FOOD RESOURCE A Dissertation Presented to the Faculty of the Graduate School of Cornell University In Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy by Kristen Brochu May 2018 © 2018 Kristen Brochu DIFFERENTIAL IMPACTS OF POLLEN QUALITY AND MICROBIAL COMMUNITIES ON GENERALIST AND SPECIALIST BEES VISITING A SHARED FOOD RESOURCE Kristen Brochu, Ph. D. Cornell University 2018 Abstract: There is mounting evidence for declines in both managed and wild pollinator species, necessitating support for wild bee populations in order to maintain pollination services. Solitary, ground-nesting bees comprise the vast majority of bees in the world; however, these important pollinators are relatively understudied and we know little about how they are impacted by resource availability, pollen quality, and microbial associates. My dissertation research uses plants of the genus Cucurbita as a case study to assess differential health concerns associated with generalist (Bombus impatiens and Apis mellifera) and specialist (Peponapis pruinosa) pollinators on a shared resource. I begin by examining how cucurbit plant chemistry varies across plant tissue types and varieties and how this variation impacts the foraging choices of both generalist and specialist bees in an agricultural system. Next, I assess the physiological costs associated with digesting cucurbit pollen for these generalist and specialist bees. Finally, I explore the microbial community associated with a specialist ground-nesting bee’s brood cells, evaluate how this community changes over space and time, and assess the most likely routes of microbial colonization into brood cells. -

The Long-horned Bee in Cornwall Patrick Saunders http://www.kernowecology.co.uk/ March 2017 Photo : Long-horned Bee Eucera longicornis P. Saunders Patrick Saunders (Kernow Ecology) Pollinator conservation and Ecological Consultant Pasadena West Looe Hill, Looe Cornwall PL13 2HJ 01503 262567 paddy @kernowecology.co.uk Summary of the status of the Long-horned Bee • The population of Cornish Long-horned Bee has declined from 24 to just 6 sites (75% decrease). The key sites have all been assessed as vulnerable. • The greatest threat is limited foraging resources. Flowering Legumes are rare, either through abandonment of cliff-top grazing, summer grazing or intensive agriculture. • Further threats are coastal erosion, resulting in nest site destruction and loss of flower-rich coastal edge habitats. Ecological requirements • A narrow range of Legume Fabaceae species dominated foraging visits and pollen samples. Kidney vetch Anthyllis vulneraria, Everlasting pea Lathyrus sylvestris, Meadow vetchling Lathyrus pratensis and White clover Trifolium repens. The study found that the bee does utilise pollen from other plant families, but it is suspected this is caused by lack of preferred Legumes. • Continuity of flowering Legume species are needed for 3 - 6 weeks. Within the peak foraging period of about 3 weeks, the bee requires both early flowering Legumes and late flowering Legumes. Most sites had one or the other, rather than both. • Individual pollen samples were usually dominated by one species. This may indicate a preference for mass flowering Legumes. • A mystery substance was present in pollen samples during the survey, not previously identified in other studies. • The bee generally uses south facing soft clay or loess cliffs for nesting, although other aspects can be used.
