However, in any given landscape there are usually a few good places to collect bees where they are concentrated, diverse, abundant, and easy to capture and there are many, many places where bees are difficult to find and collect. If you are interested in biodiversity, and taxonomic surveys, it will be important to discover these hotspots. In North America, in general, good collection locales will be places where floral composition is concentrated or unusual. If you are unfamiliar with an area, then exploring road/stream/river crossings, power line rights-of-way, railroad track rights-of-way, sand and gravel operations, open sandy areas, and wetlands are good places to start. In areas with a lot of development, the industrial sector often contains weedy lots and roadsides that also can have good numbers of bees. Note that just because there are few or no plants blooming (to your eye!), this doesn’t mean that there are no bees present. A good collecting strategy is to put out bee bowl traps (see sections below) in the morning, and return mid-day to good potential collecting sites that you spotted earlier that morning.

  • Sensory and Cognitive Adaptations to Social Living in Insect Societies Tom Wenseleersa,1 and Jelle S
    COMMENTARY COMMENTARY Sensory and cognitive adaptations to social living in insect societies Tom Wenseleersa,1 and Jelle S. van Zwedena A key question in evolutionary biology is to explain the solitarily or form small annual colonies, depending upon causes and consequences of the so-called “major their environment (9). And one species, Lasioglossum transitions in evolution,” which resulted in the pro- marginatum, is even known to form large perennial euso- gressive evolution of cells, organisms, and animal so- cial colonies of over 400 workers (9). By comparing data cieties (1–3). Several studies, for example, have now from over 30 Halictine bees with contrasting levels of aimed to determine which suite of adaptive changes sociality, Wittwer et al.

In this context, a long-standing hypothesis is that ery linked to chemical communication, as measured by the evolution of the spectacular sociality seen in in- the density of their antennal sensillae, compared with sects, such as ants, bees, or wasps, should have gone species that secondarily reverted back to a solitary life- hand in hand with the evolution of more complex style.

  • The Chemical Ecology and Evolution of Bee–Flower Interactions: a Review and Perspectives1
    668 REVIEW / SYNTHE` SE The chemical ecology and evolution of bee–flower interactions: a review and perspectives1 S. Do¨ tterl and N.J. Vereecken Abstract: Bees and angiosperms have shared a long and intertwined evolutionary history and their interactions have re- sulted in remarkable adaptations. Yet, at a time when the ‘‘pollination crisis’’ is of major concern as natural populations of both wild and honey bees (Apis mellifera L., 1758) face alarming decline rates at a worldwide scale, there are important gaps in our understanding of the ecology and evolution of bee–flower interactions. In this review, we summarize and dis- cuss the current knowledge about the role of floral chemistry versus other communication channels in bee-pollinated flow- ering plants, both at the macro- and micro-evolutionary levels, and across the specialization–generalization gradient. The available data illustrate that floral scents and floral chemistry have been largely overlooked in bee–flower interactions, and that pollination studies integrating these components along with pollinator behaviour in a phylogenetic context will help gain considerable insights into the sensory ecology and the evolution of bees and their associated flowering plants. Re´sume´ : Les abeilles et les angiospermes partagent une grande partie de leur histoire e´volutive, et leurs interactions ont produit de remarquables exemples d’adaptations mutuelles. Cependant, a` une e´poque ou` la « crise de la pollinisation » de- vient une pre´occupation majeure et ou` les populations d’abeilles sauvages et mellife`res (Apis mellifera L., 1758) font face a` des de´clins massifs a` l’e´chelle mondiale, notre compre´hension de l’e´cologie et de l’e´volution des relations abeilles- plantes demeure fragmentaire.

Island ecosystems may be particularly sensitive to the synergistic effects of climate change and biological invasions. In Hawai’i there are 21 non-native bees that have the capacity to spread pathogens and compete for resources with native bees. We performed an ensemble of species distribution models (SDM) for eight non-native bee species (Hymenoptera: Anthophila) in Hawai’i to predict climatically suitable niches across current and future climate scenarios. We found a significant difference in habitat suitability between SDMs that were constructed with specimen records from their native and non- native (Hawai’i) range. Although SDMs predict expansion of suitable habitat into higher elevations under 2070 climate scenarios, species-rich areas are predicted to stay below 500 m elevation.

  • Polarization Microscopy and Infrared Microspectroscopy of Integument Coverings of Diapausing Larvae in Two Distantly Related Nonsocial Bees
    Microscopy and Microanalysis (2018), 24,75–81 doi:10.1017/S1431927618000053 Micrographia Polarization Microscopy and Infrared Microspectroscopy of Integument Coverings of Diapausing Larvae in Two Distantly Related Nonsocial Bees Maria Luiza S. Mello1, Benedicto de Campos Vidal1 and Jerome G. Rozen, Jr.2 1Department of Structural and Functional Biology, Institute of Biology, University of Campinas, Campinas, SP 13083-862, Brazil and 2Division of Invertebrate Zoology, American Museum of Natural History, Central Park West, 79th St., New York, NY 10024, USA Abstract The larvae of the two distantly related nonsocial bees Ericrocis lata (Apidae) and Hesperapis (Carinapis) rhodocerata (Melittidae), which develop mostly under arid desert areas of North America, and that differ in that they either spin (E. lata) or do not spin (H. rhodocerata) protective cocoons before entering diapause, produce transparent films that cover the larval integument. To understand the nature of these films, their responses to topochemical tests and their characteristics when examined with fluorescence and high-performance polarization microscopy and microspectroscopy were studied. A positive staining by Sudan black B, birefringence of negative sign, and a Fourier transform-infrared (FT-IR) spectrum typical of lipids were detected for the integument covering of both species. The FT-IR signature, particularly, suggests a wax chemical composition for these lipid coverings, resembling the waxes that are used as construction materials in the honey cells produced by social bees. Considering the arid environmental conditions under which these larvae develop, we hypothesize that their covering films may have evolved as protection against water depletion. This hypothesis seems especially appropriate for H. rhodocerata larvae, which are capable of undergoing a long diapause period in the absence of a protective cocoon.

  • Arthropods of Elm Fork Preserve
    Arthropods of Elm Fork Preserve Arthropods are characterized by having jointed limbs and exoskeletons. They include a diverse assortment of creatures: Insects, spiders, crustaceans (crayfish, crabs, pill bugs), centipedes and millipedes among others. Column Headings Scientific Name: The phenomenal diversity of arthropods, creates numerous difficulties in the determination of species. Positive identification is often achieved only by specialists using obscure monographs to ‘key out’ a species by examining microscopic differences in anatomy. For our purposes in this survey of the fauna, classification at a lower level of resolution still yields valuable information. For instance, knowing that ant lions belong to the Family, Myrmeleontidae, allows us to quickly look them up on the Internet and be confident we are not being fooled by a common name that may also apply to some other, unrelated something. With the Family name firmly in hand, we may explore the natural history of ant lions without needing to know exactly which species we are viewing. In some instances identification is only readily available at an even higher ranking such as Class. Millipedes are in the Class Diplopoda. There are many Orders (O) of millipedes and they are not easily differentiated so this entry is best left at the rank of Class. A great deal of taxonomic reorganization has been occurring lately with advances in DNA analysis pointing out underlying connections and differences that were previously unrealized. For this reason, all other rankings aside from Family, Genus and Species have been omitted from the interior of the tables since many of these ranks are in a state of flux.
