A nesting aggregation of the solitary bee Megachile atrata (Hymenoptera: Megachilidae) in the Philippines [PDF]
A nesting aggregation of Megachile (Creightonella) atrata Smith in the Philippines comprised almost 300 active nests. The bees in rapid flight resemble the hornet Vespa tropica Linnaeus. The nest structure is similar to that reported for M.

The native bee fauna of the Palouse Prairie (Hymenoptera: Apoidea) [PDF]
While synoptic collections provide data on the range and general composition of the North American bee fauna, bee communities associated with specific habitats are largely uncharacterized.

To provide pollinator nesting habitat, cut dead perennial stems in their first winter
Garden management practises need to consider stem‐nesting bees and wasps to avoid destroying active nests and important nesting materials. Volunteers collected samples of dead stems (in situ where they grew) in winter, spring, summer and fall as part of a participatory research project.

Exposure of Larvae of the Solitary Bee Osmia bicornis to the Honey Bee Pathogen Nosema ceranae Affects Life History [PDF]
Wild bees are important pollinators of wild plants and agricultural crops and they are threatened by several environmental stressors including emerging pathogens. Honey bees have been suggested as a potential source of pathogen spillover.

Concentrated vulnerabilities in bees: Diet specialists have smaller geographic ranges
Niche breadth theory predicts a positive association between range size and diet breadth, which could concentrate risk among specialists, but this is not well established for bees. Using global occurrence data (range size) and natural history collection‐derived pollen data (diet breadth), we compared these traits in 633 species from six families and ...

ABSTRACT Flies (Diptera) are important pollinators in global agriculture, yet little is known about how intraspecific trait variation influences their pollination performance. We compared morphological traits, foraging behaviour and pollination‐related performance metrics between laboratory‐reared (hereafter lab‐reared) and wild populations of ...

Notes on a nest of the leafcutting bee Megachile (Moureapis) apicipennis Schrottky (Megachilidae) found in an abandoned gallery excavated by the carpenter bee Xylocopa frontalis (Olivier) (Apidae) are presented.

The Urban Heat Island Effect (UHI) can potentially subject insects to heat and desiccation stress and likely induce shifts in their cuticular hydrocarbon (CHC) profile. We expected that warmer urbanized areas favour longer chain length of hydrocarbons as well as higher abundance of n‐alkanes in three Hymenoptera species. We found that temperature, more

First report of Monoeca in Argentina, with description of two new species (Hymenoptera: Apidae) [PDF]
Two new species of the oil-collecting bee genus Monoeca Lepeletier & Audinet-Serville (Apidae: Tapinotaspidini) are described and figured from females and males captured in north - eastern Argentina.

Evolution of Peripheral Visual System in the Apoidea: A Role for Food Item Mobility?
Since larger compound eyes and ocelli altogether improve vision, one may expect that insects specialised in chasing very mobile resources possess such morphological optimisation. By analysing 77 species of bees and wasps, we have found that wasps had larger eyes, but not larger ocelli, than bees.
