About Eristalis intricaria (Linnaeus, 1758)
Scientific name: Eristalis intricaria (Linnaeus, 1758). For external morphology terminology, refer to Morphology of Diptera. Wing length measures 8.25 to 12 mm. The third antennomere is brownish-black. The arista is plumose on its basal half. Squamulae are greyish-black. The thorax and abdomen are covered with long, densely packed hairs, which range in color from tawny in the typical form to black in variety furvus Verrall. The typical form is dimorphic: the male abdomen has brownish hairs, while the female abdomen has blackish hairs, with white hairs present on the last tergite. Male genitalia of this species were figured by Hippa et al. (2001), and the larva was figured by Hartley (1961). This species has a Palaearctic distribution. Its range extends from Fennoscandia, Iceland, and the Faroes, south to central Spain, where it occurs only in montane areas at the southern limit of its range, and it is absent from most of South Europe. It is found in Ireland, and ranges east through Northern Europe, Central Europe, and the Alps, into Russia as far east as East Siberia.
