A checklist of the hoverflies (Diptera: Syrphidae) of Austria

Zootaxa, 2022
Hoverflies are a conspicuous and popular family within the Diptera. The larvae as well as the adults are able to colonize a wide range of habitats, and many species play important roles as pollinators, in pest management and nowadays in applied nature conservation issues. Despite of this, the state of knowledge on the hoverflies of Austria is deficient:

On the Abundance of Hoverflies (Syrphidae)

Oikos, 1989
Hoverfly populations are more stable than those of published analyses of other invertebrate groups. The data show clearly the importance of removing the dependence of the variance on the mean before analysis. The abundance and stability of different larval feeding types (predators, phytophages, saprophages), and of generalists and specialists are ...

Pollinators on the edge: our European hoverflies. The European red list of hoverflies

2023
This European Red List provides a summary of the conservation status of the European species of hoverflies (Diptera: Syrphidae), evaluated according to the IUCN Red List Categories and Criteria (2012a) and IUCN’s global (IUCN Standards and Petitions Committee, 2022) and regional (IUCN, 2012b) guidelines. It provides the first comprehensive, region-wide

Automatic Hoverfly Species Discrimination.

2012
An novel approach to automatic hoverfly species discrimination based on detection and extraction of vein junctions in wing venation patterns of insects is presented in the paper. The dataset used in our experiments consists of high resolution microscopic wing images of several hoverfly species collected over a relatively long period of time at ...
