Nematocera flies recorded in Serra do Courel, northwest Spain, May 2012 (Diptera: Anisopodidae, Blepharoceridae, Cylindrotomidae, Limoniidae, Pediciidae, Tipulidae and Trichoceridae) including descriptions of two new species of Limoniidae
During May 2012 Diptera were sampled in the Serro do Courel area of Lugo Province, Galicia, northwest Spain. The authors of this paper, members of the Malloch Society (see website) are active in attempting to understand the detailed ecology of flies. Much of this work is through targeting larval stages... -

The syrphids of Serra do Courel, Northern Spain and description of a new Cheilosia Meigen species (Diptera: Syrphidae)
The syrphids (Syrphidae) of Serra do Courel, a mountainous locality of just over 20,000ha at the west end of the Cantabrian Mountains, northern Spain are poorly known. The Scottish based, Malloch Society visited the locality in May 2012 and collected a total of 462 specimens of 98 syrphid species and... -

Host preferences of aphidophagous hoverflies from field distribution of their larvae
The patterns of occurrences among aphid colonies of the larvae of two species of highly polyphagous predatory hoverflies, Episyrphus balteatus (de Geer) and Syrphus ribesii (L.) (Diptera: Syrphidae), were assessed in three areas (Nottingham, Cardiff (UK) and the Czech Republic); in the last two sites, larvae of other syrphid species...Sadeghi, Hussein ; Rotheray, Graham E ; Laska, Pavel ; Gilbert, Francis

Development sites, feeding modes and early stages of seven European Palloptera species (Diptera, Pallopteridae)
Two hundred and ninety-eight rearing records and 87 larvae and puparia were obtained of seven species of Palloptera Fallén (Diptera, Pallopteridae), mainly in Scotland during 2012–2013. The third stage larva and puparium of each species were assessed morphologically and development sites and feeding modes investigated by rearing, observation and feeding...Rotheray, Graham E

Development sites and early stages of eleven species of Clusiidae (Diptera) occurring in Europe
Two hundred and ninety-six rearing records of 11 clusiid species (Diptera, Clusiidae) were obtained from 8 tree species in England, Finland, France, Norway, Russia and Scotland, mainly during the period 1994 to 2004. Larvae and puparia were found between annual layers of whitewood (sapwood and heartwood) of wet, decay-softened, dead...Rotheray, Graham E ; Horsfield, David

Hidden in taxonomy: Batesian mimicry by a syrphid fly towards a Patagonian bumblebee
1.Batesian mimicry has been repeatedly reported in syrphid flies (Diptera: Syrphidae), with noxious Hymenoptera identified as the models, including bumblebees (Hymenoptera: Aculeata). Despite the number of detailed studies of bumblebee mimics from the Holarctic, only minimal biological and ecological information is available for the same phenomenon in most other biogeographical...Polidori, C ; Nieves-Aldrey, J L ; Gilbert, Francis ; Rotheray, Graham E
