Diversity of saproxylic dance flies and long-legged flies (Diptera: Empidoidea) in a temperate deciduous forest in Quebec, Canada

“…1) and Neurigona Rondani (Fig. 2) in particular, are both found on tree trunks as adults, and certain Medetera larvae have been found on decaying sap (Rotheray et al 2001), or are well known as predators of scolytid beetle larvae in galleries under bark (Bickel 1985). Habits of the immature stages of the other dolichopodid taxa listed in Table 1 are unknown, but adults of Gymnopternus Loew, Chrysotimus Loew, Sympycnus Loew and Xanthochlorus Loew are commonly collected in woodlands, so it is not too surprising that these genera may include saproxylic species.…”

“…Nevertheless, of importance here is the large diversity of empidoid taxa recorded as saproxylic (43 species in 19 genera, representing 12 different subfamilies and three families). Only a few European studies (i.e., Hövemeyer 1998;Rotheray et al 2001;Meyer & Nötzold 2004;Meyer 2005) have reported a modest diversity of Empidoidea with saproxylic larvae. However, the association of adult empidoid taxa (collected using emergence traps and photoeklectors) with their immature stages being strictly in decaying wood, is not as compelling in most of these studies as it is in the present study, because associated soil and fungi were not completely isolated from the decaying wood substrates (e.g., mainly stumps and woody litter).…”

A kétszárnyúakhoz (Diptera) kötődő ökoszisztéma-szolgáltatások

“…Néhány Chironomidae fajt laboratóriumi toxicitás vizsgálatokra használnak, és ezek túléléséből próbálnak következtetni a különféle mérgező anyagok környezetben gyakorolt hatására (Karouna-Renier & Zehr 1999). Azok a kétszárnyú fajok, melyek nagy egyedszámban fordulnak elő, általában sokféle mikrohabitatban is élnek, alkalmasak az élőhely-minőségének vizsgálatára és természetvédelmi kezelések monitorozására (Rotheray et al 2001). A tőrös legyek (Therevidae) kvantitatív eloszlása indikátora lehet az élőhely heterogenitásának, illetve a szukcesszió állapotának felmérésére száraz területeken (Holston 2005).…”

Filling gaps in flower fly distributions: first record of Aneriophora aureorufa (Philippi, 1865) (Diptera, Syrphidae) from Argentina

“…Syrphidae is one of the most diverse and ubiquitous families in Diptera, comprising more than 200 genera and over 6,000 described species worldwide (Brown 2009, Pape andThompson 2019). Adults of flower fly are key pollinators in crops and natural ecosystem (Ssymank et al 2008, Lander et al 2009, Inouye et al 2015 and their larvae are predators, parasitoids, saprophagous, mycophagous, and phytophagous (Rotheray and Mac-Gowan 2000, Rotheray et al 2001, Weng and Rotheray 2008, Reemer and Rotheray 2009, Ureña and Hanson 2010, Mengual and Thompson 2011, Rotheray and Gilbert 2011, Zuijen and Nishida 2011, Pérez-Lachaud et al 2014, Jordaens et al 2015, Dumbardon-Martial 2016, Fleischmann et al 2016). Due to their ecological functions, flower fly larvae are used as biological control agents of pests in greenhouses and crops (White et al 1995, Pineda and Marcos-García 2008, Fidelis et al 2018 and help as decomposers of organic matter (Lardé 1989, Martínez-Falcón et al 2012).…”
