Flower Associations of Mimetic Syrphidae (Diptera) in Northern Michigan [PDF]

, 2017
Collections of specialized (high fidelity) mimetic Syrphidae in northern Michigan revealed 19 species associated with 18 flowering plants. Almost 97% of these syrphids were taken on seven plant species or species groups, all with conspicuous white or ...

Insight Into the Diversity of Flower‐Visiting Hoverflies (Diptera: Syrphidae) in Shrubland Maquis Around Ajaccio (South‐West Corsica, France)

Journal of applied entomology
With around 6000 species and 200 genera worldwide, hoverflies (Syrphidae, Diptera) are important and a diverse group of pollinators, second to wild bees (Hymenoptera).

Efficiency of two methods of sampling used to assess the abundance and species diversity of adult Syrphidae (Diptera) in mountainous meadows in the Austrian and Swiss Alps

European Journal of Entomology, 2018
The outcome of assessments of the biodiversity of a taxonomic group often depend on the sampling method. The choice of an adequate method is especially important for biomonitoring purposes.

An assessment of new character in hoverfly species delimitation using linear and geometric morphometrics – genus Merodon Meigen, 1803 (Diptera: Syrphidae) as a case study

European Journal of Taxonomy, 2023
Detection of morphologically indistinguishable cryptic species implies using an integrative taxonomic approach with a combination of molecular, contemporary morphological, ecological and other relevant analyses.

Farmers’ Preferences for Sustainable Crop Protection: An Integrated Choice and Latent Variable Approach

Sustainable Development, EarlyView.
ABSTRACT This study analyzes farmers' preferences for sustainable crop protection, focusing on Integrated Pest Management (IPM) practices by incorporating social‐psychological factors to capture economic and behavioral dimensions. Using data from German and Polish potato farmers, we apply an integrated choice and latent variable framework that combines

Distribution and pollination services of wild bees and hoverflies along an altitudinal gradient in mountain hay meadows

Ecology and Evolution, 2021
Extensively managed and flower‐rich mountain hay meadows, hotspots of Europe's biodiversity, are subject to environmental and climatic gradients linked to altitude.

Visual approach computation in feeding hoverflies

Journal of Experimental Biology, 2018
On warm sunny days female hoverflies are often observed feeding from a wide range of wild and cultivated flowers. In doing so, hoverflies serve a vital role as alternative pollinators, and suggested to be the most important after bees and bumblebees. Unless the flower hoverflies are feeding from is large, they do not readily share the space with other ...

Is bee‐avoidance by bird‐pollinated flowers driven by nectar robbing in Erica?

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Nectar robbing (consuming nectar from a perforated flower without pollinating) generally negatively affects plant fecundity, and plants exhibit multiple mechanisms in defence.
