Sampling methods for assessing Syrphid biodiversity (Diptera: Syrphidae) in tropical forests
When assessing the species richness of a taxonomic group in a specific area, the choiceof sampling method is critical. In this study, the effectiveness of three methods for sampling syrphids(Diptera: Syrphidae) in tropical forests is compared: Malaise trapping, collecting adults with an entomological net, and collecting and rearing immatures. Surveys...Marcos-Garcia, M-Angeles ; Garcia-Lopez, A ; Zumbado, M A ; Rotheray, Graham E

The natural history of Hoverflies
Hoverflies are valuable insects and particularly over the last two decades, they have started to impact on a wider range of people than just specialists. Hoverflies are known and recognised not just for their striking colours, remarkable hovering behaviour and flower visiting habits but also because of their roles in...Rotheray, Graham E ; Gilbert, Francis

Pollen feeding larvae in the presumed predatory syrphine genus Toxomerus Macquart (Diptera, Syrphidae)
The morphology and biology of the larva of Toxomerus apegiensis (Harbach, 1974) are described from Suriname. This larva feeds on pollen of Olyra obliquifolia Steudel, a bambusoid grass (Poaceae) that grows in the understorey of tropical rainforests. The morphology of the larva of Toxomerus politus (Say, 1823), which feeds on...Reemer, Menno ; Rotheray, Graham E

Rediscovery and reclassification of the dipteran taxon Nothomicrodon Wheeler, an exclusive endoparasitoid of gyne ant larvae
The myrmecophile larva of the dipteran taxon Nothomicrodon Wheeler is rediscovered, almost a century after its original description and unique report. The systematic position of this dipteran has remained enigmatic due to the absence of reared imagos to confirm indentity. We also failed to rear imagos, but we scrutinized entire...Pérez-Lachaud, Gabriela ; Jahyny, Benoit J B ; Ståhls, Gunilla ; Rotheray, Graham E ; Delabie, Jacques H C …
