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

Revision of the New World genus Quichuana Knab, 1913 (Diptera: Syrphidae), including descriptions of 24 new species.
The species of the New World syrphid genus, Quichuana Knab, 1913 (Diptera: Syrphidae: Eristalini), are revised and the genus is re-diagnosed. Twenty-four new species are described, bringing the total number considered valid to 48. New species were mostly reared from Bolivia, Brazil, Costa Rica, El Salvador, Mexico, Peru, Trinidad, and... -

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 …

Improving knowledge of the cyclorrhaphan larva (Diptera)
A significant factor in the evolution of the Cyclorrhapha (Diptera), the most biodiverse of higher dipteran taxa, is the larva. The larva also has wide-ranging trophic and environmental relationships, including positive and negative impacts on human health and wealth. Despite its importance, the larva is neglected and a low proportion...Rotheray, Graham E

Morphology of the puparium and breeding sites of eight species of Heleomyzidae (Diptera)
Rearing data from higher plants, carrion and bird and mammal nests and burrows are provided for eight species of Heleomyzidae (Diptera): Heleomyzinae: Heleomyza borealis Boheman, Scoliocentra brachypterna (Loew) and Eccoptomera microps (Meigen); Heteromyzinae: Tephrochlamys flavipes (Zetterstedt), Tephrochlamys tarsalis (Zetterstedt) and Heteromyza rotundicornis (Zetterstedt); and Suillinae: Suillia ustulata (Meigen) and Suillia...Rotheray, Graham E

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... -

Neotropical Copestylum Macquart (Diptera: Syrphidae) breeding in fruits and flowers, including 7 new species
Ten species of Copestylum (Diptera: Syrphidae) were reared from fruits and flowers in Costa Rica, Ecuador and Trinidad. Seven were new and in this paper, we describe them, their development sites and the third stage larva and/or the puparium of all ten species. One new synonym is proposed, Copestylum pinkusi...Ricarte-Sabater, Antonio ; Marcos-Garcia, M-Angeles ; Hancock, E Geoffrey ; Rotheray, Graham E

Trophic structure and function in the larva of predatory muscid flies (Diptera, Muscidae)
Assessed multiple times over a 100-year period, yet poorly understood, we provide a new view of trophic structure and function in predatory muscid larvae based on Phaonia goberti (Mik) and Phaonia subventa (Harris) (Diptera, Muscidae). Trophic structure and function were investigated by morphological analysis, direct observation and filming. Larvae search...Rotheray, Graham E ; Wilkinson, Geoffrey

Diverse mechanisms of feeding and movement in Cyclorrhaphan larvae (Diptera)
Direct observation, filmed behaviour and morphological analysis were used to investigate mechanisms of larval feeding and movement in 20 species of Cyclorrhapha (Diptera). Feeding mechanisms refer to techniques of gathering food close to the pharynx entrance prior to sucking it in. A total of 12 mechanisms were recorded. Contrasting mechanisms...Rotheray, Graham E ; Lyszkowski, Richard M
