Quantification of migrant hoverfly movements (Diptera: Syrphidae) on the West Coast of North America [PDF]
Royal Society Open Science, 2019 The seasonal migration of huge numbers of hoverflies is frequently reported in Europe from mountain passes or spurs of land. The movement of such large numbers of beneficial insects is thought to provide significant ecosystem services in terms of ...

Trait‐based effects of plant invasion on floral resources, hoverflies and bees
Insect Conservation and Diversity, 2023 Plant invasions can lead to homogeneous communities with decreased functional diversity. However, invasive plants, with various morphological and phenological traits, may drive pollinator communities in a less predictable, more complex way.

Determinants of species richness patterns in the Netherlands across multiple taxonomic groups [PDF]
, 2009 We examined the species richness patterns of five different species groups (mosses, reptiles and amphibians, grasshoppers and crickets, dragonflies, and hoverflies) in the Netherlands (41,500 km2) using sampling units of 5 × 5 km. We compared the spatial

Local and landscape effects of field margins on aerially dispersing beneficial insects and spiders [PDF]
, 2011 Field margins were implemented in UK agri-environment schemes with the aim to increase farmland biodiversity. Recently aerially dispersing aphid enemies have been shown to provide the majority of aphid control in winter wheat fields but there is a lack ...

Migratory hoverflies orientate north during spring migration
bioRxiv, 2022 Migratory hoverflies are long-range migrants that, in the northern hemisphere, move seasonally to higher latitudes in the spring and lower latitudes in the autumn.

Syrphine hoverflies are effective pollinators of commercial strawberry
Journal of Pollination Ecology, 2018 Recent declines in wild pollinators represent a significant threat to the sustained provision of pollination services. Insect pollinators are responsible for an estimated 45% of strawberry crop yields, which equates to a market value of approximately £99

The FloRes Database: A floral resources trait database for pollinator habitat-assessment generated by a multistep workflow [PDF]
Biodiversity Data Journal, 2022 The decline of pollinating insects in agricultural landscapes proceeds due to intensive land use and the associated loss of habitat and food sources. The feeding of those insects depends on the spatial and temporal distribution of nectar and pollen as ...

Hoverfly (Diptera: Syrphidae) diversity in Tapada da Ajuda, Lisbon - a preliminary study [PDF]
, 2018 Hoverflies are holometabolic insects, whose adults are pollinators feeding on nectar and pollen. Frequently, they are confused with wasps, bees and bumblebees.
