Genus Chrysotoxum Meigen

The genus Chrysotoxum comprises large, wasp-mimicking species ( van Veen 2004). Species of the genus Chrysotoxum are widely distributed in all zoogeographical regions except Australasian and the Antarctic with approximately 150 species mostly in the Palaearctic region ( Evenhuis et al. 2008; Thompson et al. 2010). The adult flies of European Chrysotoxum species can be found in deciduous and coniferous forests and grasslands ( Speight 2020). Larvae are specialized in preying upon root aphids associated with ant nests ( Rotheray & Gilbert 2011; Nedeljkovic et al. 2013; Speight 2020).
