They are often confused with wasps and other insects, but when placed under magnification one can see the tiny hairs on their faces. They do visit flowers to collect nectar for food for themselves, mainly to keep up their energy to look for host nests. Cuckoo bees do not need to collect pollen for nests as their young will feed off of the pollen placed in the nest by the host bee. Cuckoo bees are a little like cuckoo birds; they too lay their eggs in the nests of others. This practice is called cleptoparasitism. Female Cuckoo bees find the nests of other bees by smell; the male Cuckoo bee helps the females find these nests by releasing special scents near other bee’s nests. y Cransh itne aw, Wh C © SU , Cuckoo bees generally lay more eggs B u g w in the nest than the host bee, and the o o d young cuckoo bee’s larva eats all of . o r the food which was stored in the g nest by the host bee. This and the aggressive behavior of the young cuckoo bee results in death of the host bee offspring. Nomada Cuckoo bees are just one of the many Cuckoo bees in bee families, some of the others are Sphecodes, Coelioxys, and Stelis. Some of the other types of Cuckoo bees such as the Stelis will return many times to the same host bee nest and keep laying eggs in each cell as the host bee builds them. The Coelioxys Cuckoo bee larvae, like other Cuckoo bee larvae, have large mandibles that they use to kill the host bee larva or egg. The USDA is an equal opportunity provider and employer.

NUMBER 2 244 MAY I9, I 966 The Larvae of the Anthophoridae (Hymenoptera, Apoidea) Part 2. The Nomadinae BY JEROME G. ROZEN, JR.1 The present paper is the second of a series that treats the phylogeny and taxonomy of the larvae belonging to the bee family Anthophoridae. The first (Rozen, 1965a) dealt with the pollen-collecting tribes Eucerini and Centridini of the Anthophorinae. The present study encompasses the following tribes, all of which consist solely of cuckoo bees: Protepeolini, Epeolini, Nomadini, Ammobatini, Holcopasitini, Biastini, and Neolarrini. For reasons presented below, these tribes are believed to represent a monophyletic group, and consequently all are placed in the Nomadinae. It seems likely that the cleptoparasitic tribes Caenoprosopini, Ammoba- toidini, Townsendiellini, Epeoloidini, and Osirini are also members of the subfamily, although their larvae have not as yet been collected. Although the interrelationships of the numerous taxa within the Nomadinae need to be re-evaluated, the tribal concepts used by Michener (1944) are employed here. Adjustments in the classifications will certainly have to be made in the future, however, for Michener (1954) has already indicated, for example, that characters of the adults in the Osirini, the Epeolini, and the Nomadini intergrade. The affinities of the Nomadinae with the other subfamilies of the Antho- phoridae will be discussed in the last paper of the series.

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.

Food Load Manipulation Ability Shapes Flight Morphology in Females Of
Polidori et al. Frontiers in Zoology 2013, 10:36 http://www.frontiersinzoology.com/content/10/1/36 RESEARCH Open Access Food load manipulation ability shapes flight morphology in females of central-place foraging Hymenoptera Carlo Polidori1*, Angelica Crottini2, Lidia Della Venezia3,5, Jesús Selfa4, Nicola Saino5 and Diego Rubolini5 Abstract Background: Ecological constraints related to foraging are expected to affect the evolution of morphological traits relevant to food capture, manipulation and transport. Females of central-place foraging Hymenoptera vary in their food load manipulation ability. Bees and social wasps modulate the amount of food taken per foraging trip (in terms of e.g. number of pollen grains or parts of prey), while solitary wasps carry exclusively entire prey items. We hypothesized that the foraging constraints acting on females of the latter species, imposed by the upper limit to the load size they are able to transport in flight, should promote the evolution of a greater load-lifting capacity and manoeuvrability, specifically in terms of greater flight muscle to body mass ratio and lower wing loading. Results: Our comparative study of 28 species confirms that, accounting for shared ancestry, female flight muscle ratio was significantly higher and wing loading lower in species taking entire prey compared to those that are able to modulate load size. Body mass had no effect on flight muscle ratio, though it strongly and negatively co-varied with wing loading. Across species, flight muscle ratio and wing loading were negatively correlated, suggesting coevolution of these traits. Conclusions: Natural selection has led to the coevolution of resource load manipulation ability and morphological traits affecting flying ability with additional loads in females of central-place foraging Hymenoptera.

The cleptoparasite (adult and larvae) show many morphological and behavior adaptations to this life style. In this paper I present some data on the cleptoparasite bees whose hosts are bees specialized to collect floral oil. Key words: solitary bee, interspecific interaction, parasitic strategies, hospicidal larvae.

The status and distribution of solitary bee Stelis ornatula and solitary wasp Podalonia affinis on the Sefton Coast in 2019 Ben Hargreaves The Wildlife Trust for Lancashire, Manchester & North Merseyside October 2019 1 ACKNOWLEDGEMENTS Thanks to Tanyptera Trust for funding the research and to Natural England, National Trust and Lancashire Wildlife Trust for survey permissions. 2 CONTENTS Summary………………………………………………………………………………………………………….4 Introduction…………………………………………………………………………………………………….5 Aims and objectives………………………………………………………………………….6 Methods…………………………………………………………………………………………..6 Results……………………………………………………………………………………………..7 Discussion………………………………………………………………………………………..9 Follow-up work………………………………………………………………………………11 References……………………………………………………………………………………..11 3 SUMMARY The Wildlife Trust for Lancashire, Manchester & North Merseyside (Lancashire Wildlife Trust) were commissioned by Liverpool Museum’s Tanyptera project to undertake targeted survey of Nationally Rare (and regionally rare) aculeate bees and wasps on various sites on the Sefton Coast. Podalonia affinis is confirmed as extant on the Sefton Coast; it is definitely present at Ainsdale NNR and is possibly present at Freshfield Dune Heath. Stelis ornatula, Mimesa bruxellensis and Bombus humilis are not confirmed as currently present at the sites surveyed for this report. A total of 141 records were made (see attached data list) of 48 aculeate species. The majority of samples were of aculeate wasps (Sphecidae, Crabronidae and Pompilidae). 4 INTRODUCTION PRIMARY SPECIES (Status) Stelis ornatula There are 9 records of this species for VC59 between 1975 and 2000. All the records are from the Sefton Coast. The host of this parasitic species is Hoplitis claviventris which is also recorded predominantly from the coast (in VC59). All records are from Ainsdale National Nature Reserve (NNR) and Formby (Formby Point and Ravenmeols Dunes). Podalonia affinis There are 15 VC59 records for this species which includes both older, unconfirmed records and more recent confirmed records based on specimens.

Bees and Wasps of the East Sussex South Downs
A SURVEY OF THE BEES AND WASPS OF FIFTEEN CHALK GRASSLAND AND CHALK HEATH SITES WITHIN THE EAST SUSSEX SOUTH DOWNS Steven Falk, 2011 A SURVEY OF THE BEES AND WASPS OF FIFTEEN CHALK GRASSLAND AND CHALK HEATH SITES WITHIN THE EAST SUSSEX SOUTH DOWNS Steven Falk, 2011 Abstract For six years between 2003 and 2008, over 100 site visits were made to fifteen chalk grassland and chalk heath sites within the South Downs of Vice-county 14 (East Sussex). This produced a list of 227 bee and wasp species and revealed the comparative frequency of different species, the comparative richness of different sites and provided a basic insight into how many of the species interact with the South Downs at a site and landscape level. The study revealed that, in addition to the character of the semi-natural grasslands present, the bee and wasp fauna is also influenced by the more intensively-managed agricultural landscapes of the Downs, with many species taking advantage of blossoming hedge shrubs, flowery fallow fields, flowery arable field margins, flowering crops such as Rape, plus plants such as buttercups, thistles and dandelions within relatively improved pasture. Some very rare species were encountered, notably the bee Halictus eurygnathus Blüthgen which had not been seen in Britain since 1946. This was eventually recorded at seven sites and was associated with an abundance of Greater Knapweed. The very rare bees Anthophora retusa (Linnaeus) and Andrena niveata Friese were also observed foraging on several dates during their flight periods, providing a better insight into their ecology and conservation requirements.

Tips on Using a Native Bee Collection at a Public Event by Addison Deboer and Andony Melathopoulos, Oregon State University Extension
Tips on Using a Native Bee Collection at a Public Event By Addison DeBoer and Andony Melathopoulos, Oregon State University Extension Native Bee Displays: Each Oregon Bee Atlas team will get a wooden display box with bees grouped by Family and Genus. These boxes cannot be shipped, so need to be transferred when Rich, Sarah or Andony travel to your community. You will be given a basic complement of bees that you can supplement as you gather your own specimens. The base case will contain specimens from the following groups: Family: genus Colletidae: Hylaeus Halictidae: Agapostemon, Halictus, Lasioglossum Apidae: Ceratina, Bombus, Nomada, Melissodes, Apis mellifera Megachilidae: Osmia, Stelis, Heriades, Megachile, Anthidium Andrenidae: Andrena Bee look-alikes: flies, wasps The following manual will provide you with tips on how to use these displays for public tabling events. Activities are broken up into short “attention getters” that are designed to get people interested at high volume events and “longer conversations” if you end up with someone with a lot more interest. Also, included are some natural history notes on all the bees, so you can dive in a little deeper if you have someone who is keen. Attention-getters (10 second conversation): 1. Most bees are like gophers, 70% of all bees live in the ground: • Point to Andrena and the Hallitcitidae as two families that nest almost exclusively underground – these two families make up the bulk of Oregon bees. 2. Hylaeus secrete cellophane-like material to line their nest cells • Point out that bees line their nests to protect their young from the environment, but also from parasites – the pollen ball they collect is a valuable resource.
