The effects of flower supplementation on pollinators and pollination along an urbanisation gradient
Enhancing urban greenspaces for pollinator communities by planting flower patches is increasingly common, but their efficacy for different groups of insects (bees, hoverflies and moths) is unclear. Our city‐scale experiment demonstrated that the effect of flower patches on pollinators is complex, and direct benefits to specific insects are difficult to

Two species of Megachile Latreille, 1802 new to the Iberian Peninsula (Hymenoptera, Megachilidae)
Identification of material obtained in various bee surveys at several sites across Catalonia (NE Spain) has revealed the occurrence of two species of Megachile previously unrecorded from the Iberian Peninsula: Megachile (Megachile) alpicola and Megachile

A dozen of new species of orchid bees (Hymenoptera: Euglossini) from Brazil and Ecuador
New species of orchid bees, eleven from Brazil and one from Ecuador, are here described, two in the genus Eufriesea (Ef. aequatoriana sp. nov. and Ef. patrice sp. nov.), seven in Euglossa (Euglossa) (Eg. aeneolusa sp. nov., Eg. caruaruensis sp. nov., Eg.

Abstract Habitat fragmentation is widespread globally, but the effects of fragmentation on populations and communities are often unclear. Because species responses to fragmentation are interdependent, examining how fragmentation alters species interactions may clarify community responses to fragmentation. In a large, replicated fragmentation experiment,

Das Vorkommen von Botrytis anthophila bond. in Proben von Handelssaatgut Finnischen Rotklees
Aus Samenproben vom südlichen und mittleren Finnland wurde ein Pilz Botrytis anthophila Bond, isoliert, der die Staubbeutel von Rotklee vernichtet. Dieser Pilz ist nicht früher in Finnland gefunden worden. Nach Literatur hat er einen schädlichen Einfluss

This study develops a quantitative framework that integrates field data, epidemiological models, simulations, and Bayesian inference to identify key viral hosts in multispecies bee communities. By estimating species‐specific R0 values from flower‐visitor networks and viral screening, we show that honeybees, as well as other wild bees, can drive the ...

The co‐adaptation of bees from the genus Macropis and Lysimachia plants has been studied in detail. Research shows that bees collect not just pure liquid oil from flower petals but tear off trichome heads filled with oil, transferring them to their nests.

Review of the Icelandic bee fauna (Hymenoptera: Apoidea: Anthophila) [PDF]
Only one species of the Hymenoptera Apoidea Anthophila is native to Iceland: Bombus jonellus (Kirby, 1802). A second species, Andrena tarsata Nylander, 1848, is mentioned by Schmiedeknecht (1882–1884), but there is reasonable doubt of an existence in Iceland. Four bumblebee species were introduced: B. hortorum (Linnaeus, 1761), first detection in 1959;

Notes are provided on the morphology of males and females of the enigmatic Lithurgus huberi Ducke (Lithurginae: Lithurgini), a species historically believed to have been introduced into South America from Asia and to be a possible synonym of the more ...

Wolbachiainfections in bees (Anthophila) and possible implications for DNA barcoding
The widespread intracellular bacterium Wolbachia is transmitted exclusively maternally and alters the reproduction of its hosts by different mechanisms. Thereby, inheritance patterns of mitochondrial genomes are modified, possibly confining interpretations of mitochondrial sequence data.
