Wild Bees of Grand Staircase-Escalante National Monument: Richness, Abundance, and Spatio-Temporal Beta-Diversity
Wild bees of Grand Staircase-Escalante National Monument: richness, abundance, and spatio-temporal beta-diversity Olivia Messinger Carril1, Terry Griswold2, James Haefner3 and Joseph S. Wilson4 1 Santa Fe, NM, United States of America 2 USDA-ARS Pollinating Insects Research Unit, Logan, UT, United States of America 3 Biology Department, Emeritus Professor, Utah State University, Logan, UT, United States of America 4 Department of Biology, Utah State University - Tooele, Tooele, UT, United States of America ABSTRACT Interest in bees has grown dramatically in recent years in light of several studies that have reported widespread declines in bees and other pollinators. Investigating declines in wild bees can be difficult, however, due to the lack of faunal surveys that provide baseline data of bee richness and diversity. Protected lands such as national monuments and national parks can provide unique opportunities to learn about and monitor bee populations dynamics in a natural setting because the opportunity for large-scale changes to the landscape are reduced compared to unprotected lands. Here we report on a 4-year study of bees in Grand Staircase-Escalante National Monument (GSENM), found in southern Utah, USA. Using opportunistic collecting and a series of standardized plots, we collected bees throughout the six-month flowering season for four consecutive years. In total, 660 bee species are now known from the area, across 55 genera, and including 49 new species. Two genera not previously known to occur in the state of Utah were discovered, as well as 16 new species records for the state. Bees include ground-nesters, cavity- and twig-nesters, cleptoparasites, narrow specialists, generalists, solitary, and social species. -

A Visual Guide for the Identification of British Coelioxys Bees
1 Introduction The Hymenoptera is an order of insects that includes bees, wasps, ants, ichneumons, sawflies, gall wasps and their relatives. The bees (family Apidae) can be recognised as such by the presence of feather-like hairs on their bodies, particularly near the wing bases. The genus Coelioxys Latreille belongs to the bee subfamily Megachilinae. There are six species of Coelioxys present in mainland Britain. Two other species are found in Guernsey but not mentioned in this pictorial key (C. afra Lepeletier and C. brevis Eversmann). Natural History Coelioxys (their various English names are: Sharp-tailed Bees, Sharp-abdomen Bees and Sharp-bellied Bees) are among those known as cuckoo bees because the larvae grow up on food stolen from Leaf-cutter Bees (Megachile Latreille) or Flower Bees (Anthophora Latreille). The genus Megachile probably includes the closest relatives of Coelioxys. Female Megachile construct nests of larval cells from leaves and provision each cell with a mixture of pollen and nectar for the young. A female Coelioxys will seek these out and apparently uses its sharp abdomen to pierce the cells. An egg is then laid in the Megachile cell. The egg of the Coelioxys hatches before that of the Megachile and the newly-hatched larva crushes the Megachile egg with its large jaws. The Coelioxys larva can then feed on the contents of the cell. Pupation occurs within a cocoon spun within the host cell where the larva overwinters as a prepupa. The genus Anthophora excavates nest burrows in sandy soil or rotting wood, where they may also become the hosts of Coelioxys larvae. -

Wisconsin Bee Identification Guide
WisconsinWisconsin BeeBee IdentificationIdentification GuideGuide Developed by Patrick Liesch, Christy Stewart, and Christine Wen Honey Bee (Apis mellifera) The honey bee is perhaps our best-known pollinator. Honey bees are not native to North America and were brought over with early settlers. Honey bees are mid-sized bees (~ ½ inch long) and have brownish bodies with bands of pale hairs on the abdomen. Honey bees are unique with their social behavior, living together year-round as a colony consisting of thousands of individuals. Honey bees forage on a wide variety of plants and their colonies can be useful in agricultural settings for their pollination services. Honey bees are our only bee that produces honey, which they use as a food source for the colony during the winter months. In many cases, the honey bees you encounter may be from a local beekeeper’s hive. Occasionally, wild honey bee colonies can become established in cavities in hollow trees and similar settings. Photo by Christy Stewart Bumble bees (Bombus sp.) Bumble bees are some of our most recognizable bees. They are amongst our largest bees and can be close to 1 inch long, although many species are between ½ inch and ¾ inch long. There are ~20 species of bumble bees in Wisconsin and most have a robust, fuzzy appearance. Bumble bees tend to be very hairy and have black bodies with patches of yellow or orange depending on the species. Bumble bees are a type of social bee Bombus rufocinctus and live in small colonies consisting of dozens to a few hundred workers. Photo by Christy Stewart Their nests tend to be constructed in preexisting underground cavities, such as former chipmunk or rabbit burrows. -
Seasonal and Spatial Patterns of Mortality and Sex Ratio in the Alfalfa
Seasonal and spatial patterns of mortality and sex ratio in the alfalfa leafcutting bee, Megachile rotundata (F.) by Ruth Pettinga ONeil A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science in Entomology Montana State University © Copyright by Ruth Pettinga ONeil (2004) Abstract: Nests from five seed alfalfa sites of the alfalfa leafcutting bee Megachile rotundata (F.) were monitored over the duration of the nesting season in 2000 and 2001, from early July through late August. Cells containing progeny of known age and known position within the nest were subsequently analyzed for five commonly encountered categories of pre-diapause mortality in this species. Chalkbrood and pollen ball had the strongest seasonal relationships of mortality factors studied. Chalkbrood incidence was highest in early-produced cells. Pollen ball was higher in late-season cells. Chalkbrood, parasitism by the chalcid Pteromalus venustus, and death of older larvae and prepupae , due to unknown source(s) exhibited the strongest cell-position relationships. Both chalkbrood and parasitoid incidence were highest in the inner portions of nests. The “unknown” category of mortality was highest in outer portions of nests. Sex ratio was determined for a subset of progeny reared to adulthood. The ratio of females to males is highest in cells in inner nest positions. Sex ratio is female-biased very early in the nesting season, when all cells being provisioned are the inner cells of nests, due to the strong positional effect on sex ratio.

Some leafcutting bees, Osmia spp., are even used as commercial pollinators (like Description honey bees) in crops such as alfalfa and blueberries. Most leafcutting bees are moderately sized (around the size of a honey bee, ranging from 5 mm to 24 mm), stout-bod- ied, black bees. The females, except the parasitic Coelioxys, carry pollen on hairs on the underside of the abdomen rather than on the hind legs like other bees. When a bee is carrying pollen, the underside of the abdomen appears light yellow to deep gold in color. Biology Leafcutting bees, as their name implies, use 0.25 to 0.5 inch circular pieces of leaves they neatly cut from plants to construct nests. They construct cigar-like nests that contain several cells. Each cell contains a ball or loaf of stored pollen and a single egg. Therefore, each cell will produce a Figure 1.

Bees of Sub-Saharan Africa Poster
Bees of Sub-Saharan Africa It is estimated that there are around 30 000 bee species worldwide of which about 20 500 have been described, 2755 occur in sub-Saharan Africa and about 1200 occur in South Africa. Bees, in many shapes and sizes, pollinate about 80% of all flowering plants and 75% of the vegetables, fruits and nuts we eat. The symbols next to each bee indicate their sociality, where they nest and where they get their food. Megachilidae are long tongued bees with two submarginal cells on their wings that collect pollen Apidae are long tongued bees with two or three submarginal wing cells that collect pollen on their hind legs. under their abdomens. The group comprises almost every type of nest building behaviour. Most are solitary but some are social. Parasitism includes social parasites, cleptoparasites and robbers. ♂ ♂ ♀ ♀ ♀ ♀ ♀ ♂ C ♀ C ♀ ♂ F Pasites ♀ appletoni C C F Cleft Cuckoo Ammobates ♀ Nomada gigas Bee auster Gnathanthidium Wasp Cuckoo Sandwalker prionognathum Bee Cuckoo Bee F Big Jawed Afromelecta fulvohirta Euaspis abdominalis Xylocopa lugubris Fidelia braunsiana Redtailed Cuckoo Bee Carder Bee Coelioxys circumscriptus Large Carpenter Bee Pathwork Cuckoo Bee Pot Bee Cone Cuckoo Bee ♀ ♂ ♀ ♀ ♂ C ♂ ♀ F ♂ C ♂ ♀ ♀ ♂ ♀ ♀ F ♀ ♂ F Ceratina Sphecodopsis Icteranthidium ♀ ♂ Schwarzia emmae moerenhouti Max Cuckoo Bee vespericena F grohmani Small Carpenter Bee Cape Cuckoo Ridge Cheeked Bee C F Hoplitis similis Carder Bee F Lithurgus spiniferus Big Resin Bee Aglaoapis trifasciata Stone Bee Toothed Cuckoo Bee F ♀ ♂ ♀ ♂ Aspidosmia arnoldi ♀ ♂ Ugly Faced Carder Bee ♀ F ♀ ♀ Thyreus pictus Xylocopa scioensis F F Neon Cuckoo Bee Afroheriades sp. ♀ Large Carpenter Bee Compsomelissa Macrogalea candida African Resin Bee Ochreriades F ♀ Stenoheriades sp. -

Here we examine nest site selection in the solitary, resource defense polygynous bee, Anthidium manicatum. Using a wood-framed screen enclosure outfitted with food sources, nesting materials, and bam- boo trap nests, we show that female bees prefer to initiate nests in sites located high above the ground. We also show that nest sites located at higher levels are less likely to contain spiderwebs, suggesting an adaptive explanation for nest site height preferences. We report size differences between this study’s source populations in Boston, Massachusetts and Brooklyn, New York; male bees collected in Boston have smaller mean head widths than males collected in Brooklyn. Finally, we argue that methods for studying captive populations of A. manicatum hold great promise for research into sexual selection, alternative phenotypes, recognition systems, and the evolution of nesting behavior.
