The Afrotropical hoverflies remain an understudied group of hoverflies. One the reasons for lack studies on this resides in difficulties to delimit species using available identification keys. DNA barcoding has been found useful such cases taxonomical uncertainty. Here, we present a molecular study hoverfly from eastern Free State South Africa mitochondrial cytochrome-c oxidase subunit I gene (...

Urban and peri-urban forests are important habitats for maintaining biodiversity in cities. In this paper, we report a method using hoverflies as indicators urban forest habitats. As case study, three were assessed compared to rural Slovenia. Rožnik (Ljubljana) was chosen the site, Mestni log Brdo (Kranj) sites, eight sites different ecoregions Forest hoverfly species richness composition of bi...

Many palatable insects, for example hoverflies, deter predators by mimicking welldefended insects such as wasps. However, for human observers, these flies often seem to be little better than caricatures of wasps – their visual appearance and behaviour are easily distinguishable. This imperfect mimicry baffles evolutionary biologists, because one might expect natural selection to do a more thoro...

A computational model of a stealth strategy inspired by the apparent mating tactics of male hoverflies is presented. The stealth strategy (motion camouflage) paradoxically allows a predator to approach a moving prey in such a way that it appears to be a stationary object. In the model, the predators are controlled by neural sensorimotor systems that base their decisions on realistic levels of i...
