Hoverflies of Serbia: What suits them better – Protected Areas or Prime Hoverfly Areas?
Biodiversity is declining on a global level, which raises the question of efficiency of Protected Areas (PAs). Furthermore, PAs are often established for political or economic reasons, rather than based on ecological principles, or scientific criteria.

Hoverflies and blowflies have distinctly different flight styles. Yet, both species have been shown to structure their flight behaviour in a way that facilitates extraction of 3D information from the image flow on the retina (optic flow).

The evolution of imperfect mimicry in hoverflies [PDF]
Ideas about the evolution of imperfect mimicry are reviewed. Their relevance to the colours patterns of hoverflies (Diptera, Syrphidae) are discussed in detail. Most if not all of the hoverflies labelled as mimetic actually are mimics.

Comprising nearly 300 described species, Eumerus Meigen, 1822, is one of the most speciose syrphid genera worldwide, and its taxonomic diversity is remarkable in the Mediterranean basin.
