  • 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.

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.

  • 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.

  • Nest Site Selection in the European Wool-Carder Bee, Anthidium Manicatum, with Methods for an Emerging Model Species*

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.

  • Sphecos: a Forum for Aculeate Wasp Researchers
    SPHECOS Number 12 - June 1986 , A Forum for Aculeate Wasp Researchers Arnold S. Menke, Editor , Terry Nuhn, E(lj_torial assistant Systematic Entcnology Laboratory Agricultural Research Service, USDA c/o U. s. National Museum of Natural History \olashington OC 20560 (202) 382 1803 Editor's Ramblings Rolling right along, here is issue 12! Two issues of that wonderful rag called Sphecos for the price of one! This number contains a lot of material on collections, collecting techniques, and collecting reports. Recent literature, including another vespine suppliment by Robin Edwards, rounds off this issue. Again I owe a debt of thanks to Terry Nuhn for typing nearly all of this. Rebecca Friedman and Ludmila Kassianoff helped with some French and Russian translations, respectively. Research News John Wenzel (Snow Entomological Museum, Univ. of Kansas, Lawrence, Kansas 66045) writes: "I am broadly interested in problems of chemical communication, mating behavior, sex ratio, population genetics and social behavior. I am currently working on a review of vespid nest architecture and hope that I can contribute something toward resolution of the relationships of the various genera of the tribe Polybiini. After visiting the MCZ, AMNH and the USNM I conclude that there are rather few specimens of nests in the major museums and I am very interested in hearing from anyone who has photos or reliable notes on nests that are anomolous in form, placement, or otherwise depart from expectations. I am especially interested in seeing some nests or fragments of the brood region of any Polybioides or Parapolybia. Tarlton Rayment Again RAYMENT'S DRAWINGS - ACT 3 by Roger A.
