Przestrzenne i czasowe zróżnicowanie Apoidea w lasach Wielkopolskiego Parku Narodowego

Results of the investigations of spatial and temporal differentiations of Apoidea in the forests of Wielkopolski National Park were presented. It was shown that the both forest floor differ with the degree of species differentiation and domination’s structure and total number of bees. In the herbaceous layer of the forests about twice as many spedes were found than in the crowns. Also the Shannon-Weaver’s indices for bees communities of the herbs layer are higher in all three investigated forest ecosystems. The curves of Apoidea numbers in tree crowns and forest floor were similar. The curves of Apoidea numbers in the deciduous forests have one peak in the first days of May. Whereas the curves of Apoidea numbers in the pine forest have multi peak course. It was proved that trees play an important role in feeding chain of bees inhabiting deciduous forests.Zadanie pt. „Digitalizacja i udostępnienie w Cyfrowym Repozytorium Uniwersytetu Łódzkiego kolekcji czasopism naukowych wydawanych przez Uniwersytet Łódzki” nr 885/P-DUN/2014 dofinansowane zostało ze środków MNiSW w ramach działalności upowszechniającej naukę

Wpływ barw pułapek Moerickego na liczebność i zróżnicowanie pozyskiwanych pszczół (Apoidea, Hymenoptera)

In deciduous and pine forests the effect of white, yellow and Ыие Moericke traps on numbers and sped es diversity of Apoidea was assessed. It was proven that the most useful in forest are white traps. They caught several times greater numbers of bees. The white traps caught also over 90% of all determined spedes while the yellow ones 56.4% and the blue traps only 31.6%.W lesie liściastym i sosnowym oceniono wpływ białych, żółtych i niebieskich pułapek Moerickego na liczebność i zróżnicowanie pozyskiwanych Apoidea. Wykazano, że najbardziej przydatne do odławiania Apoidea w lasach są pułapki białe. Stwierdzono kilkakrotnie wyższe liczebności pszczół odłowionych przez białe pułapki. Trafiło też do nich ponad 90% wszystkich stwierdzonych gatunków, podczas gdy do żółtych 56.4% i 31.6% do niebieskich.Zadanie pt. „Digitalizacja i udostępnienie w Cyfrowym Repozytorium Uniwersytetu Łódzkiego kolekcji czasopism naukowych wydawanych przez Uniwersytet Łódzki” nr 885/P-DUN/2014 dofinansowane zostało ze środków MNiSW w ramach działalności upowszechniającej naukę

First Records of the Adventive Pseudoanthidium nanum (Mocsáry) (Hymenoptera: Megachilidae) in Illinois and Minnesota, with Notes on its Identification and Taxonomy

We report the first records of Pseudoanthidium nanum (Mocsáry) in Illinois and Minnesota in 2016 and 2018, respectively. This represents a relatively rapid expansion since P. nanum was first detected in New Jersey in 2008. In order to help monitor the spread of this bee, we provide information on how to identify P. nanum and provide images of the general habitus, diagnostic features, and male genitalia. Finally, we confirm the taxonomic identity of P. nanum in the United States and highlight potential impacts on native anthidiines

Hylaeus (Hylaeana) dominicalis, a new species and the first colletid bee recorded from Dominica, Lesser Antilles

A new species of colletid bee, Hylaeus (Hylaeana) dominicalis Gibbs, new species, is described and figured from the Commonwealth of Dominica. The new species can be distinguished from consubgeneric species in the Caribbean Islands based on the integumental coloration, facial fovea, and pubescence. A list of all known Hylaeus from the Caribbean Islands is provided

\u3ci\u3eAnthidium Oblongatum\u3c/i\u3e (Apoidea: Megachilidae) Confirmed as a Michigan Resident, with Notes on Other Michigan \u3ci\u3eAnthidium\u3c/i\u3e Species

The Palearctic wool-carder bee, Anthidium oblongatum (Illiger) is newly documented in Michigan, with vouchers from Kent, Washtenaw, and Wayne Counties. Additional Michigan records are provided for Anthidium manicatum (L.) and the native Anthidium psoraleae Robertson

The bees of Greater Puerto Rico (Hymenoptera: Apoidea: Anthophila)

The bee fauna of the Greater Puerto Rico area was studied. A review of the previous relevant studies is presented. An annotated catalog and information about the origin and distributional patterns are also provided. Thirty-nine species of bees occur in Puerto Rico and adjacent islands. This fauna is composed of four elements: exclusive Puerto Rican endemics (26.5%); Antillean endemics occurring on multiple islands (76.5%); continental species that have also colonized the Antilles (23.5%); and species introduced through human activity (12.8%). The bee fauna was both low in its diversity and showed the highest level of disharmony in relation to other faunas of the Greater Antilles. A lectotype is here designated for Agapostemon krugii Wolcott, 1936

Preliminary checklist of the bees of St. Eustatius, Lesser Antilles (Hymenoptera: Apoidea: Anthophila)

We present a preliminary checklist of bees (Hymenoptera: Apoidea: Anthophila) compiled for St. Eustatius, an island located in the Lesser Antilles of the eastern Caribbean. The list has nine species, including six that have not been previously documented on St. Eustatius. One species is exotic to the Caribbean, one species is found only on St. Eustatius and St. Kitts, and five species occur elsewhere in the Lesser and Greater Antilles. Two of the collected specimens could not be assigned to a species; their geographical distributions are unknown

Historical and recent investigations on the bee fauna of Taiwan (Hymenoptera, Apoidea)

The bee fauna of Taiwan was studied intensively in the first half of last century and was based in large parts on the extensive material collected by Hans Sauter between 1902 and 1914. Subsequent studies on bees of Taiwan have only been sporadic. Within a cooperation between the above mentioned institutions the bee fauna was reinvestigated. It was shown how insufficiently the bee fauna of Taiwan had been investigated so far, in particular, the higher mountain regions. Now about 150 species of bees, belonging to 32 different genera, are known from Taiwan, ten of which have been described or recognized as new for science by the recent cooperation

A new species of Mermiglossa from Kenya, with comments on the arrangement of Old World Panurginae (Hymenoptera: Andrenidae)

A new species of the panurgine bee genus Mermiglossa Friese (Panurginae) is described and figured from females captured near Voi in the southern part of the former Coast Province, Kenya, a historical type locality for several bee species.  Mermiglossa voicola Ascher & Engel, new species, is distinguished from the only other species of the genus, M. rufa Friese from central Namibia.  The new species is readily identified due to its black rather than red metasoma and compound eyes slightly convergent above rather than parallel-sided.  The new species raises the total number of described bee species for Kenya to 343, extends the known distribution of its genus and subtribe from the Namib Desert of southwestern Africa to the western edge of the Nviri Desert of East Africa, and provides further evidence of extensive biogeographic connections between these disjunct xeric areas.  Recent changes in the family-group classification of Old World Panurginae are discussed in relation to recognition of Mermiglossina as a valid subtribe within an expanded tribe Panurgini also including the New World perditines

Bees (Hymenoptera: Apoidea) of the Kitty Todd Preserve, Lucas County, Ohio

A survey of the bees occurring on the The Nature Conservancy’s Kitty Todd Preserve in the Oak Openings region of Lucas County Ohio was conducted in 2002-2004, using hand-netting techniques. Collecting effort totaled 24.5 hours spread over 11 different days in the three years. All sampling was done in natural communities. One hundred twenty-four species of bees were identified from fifty-one species of flowering plants, including several bee species poorly known or infrequently collected. Comments are provided about the faunistics, bee-plant relationships, oligolecty, management, and natural community dependency of the bees found on the Kitty Todd Preserve
