Species-specific flight styles of flies are reflected in the response dynamics of a homologue motion sensitive neuron

open access: yesFrontiers in Integrative Neuroscience, 2012
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 OCCURRENCE FREQUENCY OF Syrphidae (Diptera) SPECIES IN APPLE ORCHARDS AND ON THEIR EDGES

open access: yesActa Scientiarum Polonorum: Hortorum Cultus, 2013

The evolution of imperfect mimicry in hoverflies [PDF]

open access: yes, 2004
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.
