FAROESE HOVERFLIES (DIPTERA: SYRPHIDAE).
CHECK-LIST UP TO THE YEAR 2000
tion belonging to the author, which will be
donated to the Faroese Museum of Natural
History at a later date.
Materials and Methods
From 1992 to 31 December 1999, hover-
flies have been caught at 67 different loca-
tions (and in 6 other locations before 1927)
in the Faroes. Ernst Torp determined all
hoverflies caught between 1992 and 1995.
Since then, common species have been de-
termined by the author with guidance from
Stubbs (1996), Stubbs and Falk (1983),
Torp (1994), and Verlinden (1991). Most
of the new species for the Faroes, as well as
the dubious, were determined and/or con-
trolled by Ernst Torp or C. W. Plant. Spec-
imens caught and determined by the author
himself do not have a “det.” reference. As
for “Distribution’ in neighbouring coun-
tries of the Faroe Islands, the author was
guided by Jensen (1994), Johnston (1999),
Nielsen (1999), Ólafsson (1991), and Pen-
nington (1999). For “Status”, the author
was guided by Parsons (1996), Stubbs and
Falk (1983), Torp (1994), and Truscott
(1998), together with personal observa-
tions. All hoverflies from Stóra Dímun
were caught by Kinna úr Dímun.
There are two species from Becker
(1915) that the author cannot corroborate.
Recent statements indicate that they have
been caught in the Faroes. The first is
Platycheirus immarginatus (Stæger in
Zetterstedt, 1849). Dampf and Rosen
caught two females of this species in 1912
(Becker, 1915). According to the author,
females of the species are difficult to deter-
mine and without verification they cannot
Fig. 1. The black dots indicate where hoverflies were
caught from 1992 up to and including 1999. The clear
dots indicate where hoverflies were caught before
1927 and where nofurther research has been done be-
tween 1992 and 2000. No registration of hoverflies in
the Faroe Islands has been publishedfor the period
1927 to 1992.

Melanogaster hirtella (Loew, 1843)

female was caught on 12 August 1912 by
Dampf and Rosen (Becker, 1915) in Tór-
