Hoverflies: the garden mimics. [PDF]
, 2008 The article offers information on hoverflies, a kind of fly that has bright colours and darting flight. Many of these brightly coloured hoverflies look like bees or wasps, and they use this to protect themselves. Batesian mimicry is where a palatable animal gains protection from resembling a noxious animal so that predators are deceived. Mimicry is far

Understanding the mechanism of facilitation in hoverfly TSDNs. [PDF]
PLoS Comput BiolMany animals use visual motion cues to track and pursue small, fast-moving targets, such as prey or conspecifics. In target-pursuing insects, including dragonflies and hoverflies, Small Target Motion Detector (STMD) neurons are found in the optic lobes and are believed to be presynaptic to Target Selective Descending Neurons (TSDNs) that project to ...

New data about hoverflies diversity (Insecta: Diptera: Syrphidae) on the Fruška Gora mountain, Serbia [PDF]
Zbornik Matice Srpske za Prirodne Nauke, 2002 The hoverflies fauna of the Fruška Gora Mountain is well known on account of long-term investigations conducted on the location (1956-2002). Previously, the list of hoverflies had included 203 species (Vujić and Glumac, 1994). Based on new investigations,

Protected areas and prime hoverfly areas: Safe haven for hoverflies or not?
Entomological Science, 2020 AbstractThe efficiency of protected areas (PAs) has often been questioned due to global decline of biodiversity. Invertebrates, especially insects, have been historically underrepresented in conservation studies. Our study focuses on hoverflies, an important group of insect pollinators and proven to be good bioindicators. Research was focused in Serbia,

Contrasting effects of altitude on species groups with different traits in a non-fragmented montane temperate forest [PDF]
Nature Conservation, 2019 Temperature has strong effects on species composition and traits. These effects can differ within and between species groups. Thermoregulation and mobility are traits which can be strongly affected by altitudinal distribution.

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 ...
