“…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). Furthermore, adults and larvae are good bioindicators of the quality of environments and ecosystems (Sommaggio 1999, Burgio and Sommaggio 2007, Sommaggio and Burgio 2014, Popov et al 2017.…”
