Checklist of Hungarian Sphecidae and Apidae species (Hymenoptera, Sphecidae and Apidae)
Checklist of Hungarian sphecoid wasps (Sphecidae) and bees (Apidae). 306 Sphecidae and 704 Apidae species are listed. Species, which were collected 50 years or earlier, treated as extinct species. I have not seen voucher specimen of the following species: Halictus varipes, Halictus carinthiacus, Hylaeus hungaricus, Osmia hybrida, Osmia versicolor ...

Abstract Mutualistic interactions between plants and pollinators are fundamental to biodiversity maintenance and ecosystem resilience, yet their dynamics across space and time in tropical dry forests have not been widely examined. We analyzed plant–pollinator networks across seasons and habitat types in the highly seasonal and fragmented dry forest of ...

Increasing local floral richness can support pollination success of specialised plants in dense urban landscapes. However, a floral enrichment strategy alone is less effective for generalist plants, which are typically more abundant in plant communities.

Contactless Acoustic Trapping of Hoverflies for Behavioral Studies
We present a contactless tethering device based on acoustic levitation. Opposing ultrasonic transducers generate standing waves, creating stable pressure nodes that enable the sustained levitation of hoverflies (Episyrphus balteatus). We show that acoustic levitation does not appear to affect hoverfly behavior.

Effects of flower patch additions and urbanisation on cavity‐nesting bees and wasps
Urbanisation can negatively affect cavity‐nesting bees and wasps, yet common conservation interventions such as flower patches and artificial nests lack strong empirical support. In a 2‐year experiment across urban allotments spanning an urbanisation gradient, we found no effect of added floral resources on nest uptake, while hymenopteran abundance ...

ABSTRACT Wasps, members of over 90 hymenopteran families, exhibit diverse behaviours, including pollination, predation and parasitism. While wasps are known pollinators in specialised systems, such as the intricate mutualism of fig trees and the deceptive pollination of certain orchids, they have historically been considered ineffective pollinators ...
