Úrtak
Eitt dagført yvirlit yvir blómuflugur, sum eru skrásettar
í Føroyum. Til samans eru 27 sløg í yvirlitinum, og av
teimum eru tær 15 funnar fyri fyrstu ferð á rannsóknar-
ferðum í tíðarskeiðinum frá 1992 til 2000. 2 flugusløg,
ið vóru skrásettar í gomlu listunum, eru strikaðar í
hesum yvirlitinum, tí tær eru ov ivasamar. 011 tey
nýggju skrásettu blómuflugusløgini eru merkt við *.
Abstract
Presented here is an updated checklist of hoverflies
recorded in the Faroe Islands. A total of 27 hoverfly
species are listed, 15 of which are recorded for the first
time in the Faroe Islands.
Introduction
Two hundred and eighteen years have gone
since J.C. Svabo in 1781-82 (Svabo, 1959:
241) wrote: "Fluá, musca domestica. Mus-
ca pendula is also found here". Musca pen-
dula could very well be Helophilus pendu-
lus L. or another syrphid-fly (!) in Lyne-
borg (1968). Hansen (1881) gave the fírst
real contribution to the knowledge of the
diptera fauna of the Faroes. Up to 1968,
successive entomologists collected diptera
Brachycra and Cyclorrhapha in the Faroes:
Walker (1890), Lundbeck (1913), Becker
(1915), Stein (1915), Ringdahl (1925), and
Kryger (unpubl. collection 1925 and 1926).
A total of 13 species of Syrphidae is pub-
lished in Lyneborg (1968). The hoverfly
breakthrough came in 1992 when Hugo N.
Christensen spent 14 days on a hoverfly-
catching expedition in the Faroes. He
turned the author’s interest towards this
subject and the collection of hoverflies in-
creased. More than 3,400 hoverflies have
been collected in the intervening years.
The greater part of the locations was cen-
tred in and near towns and villages. As a
consequence, more catching in isolated ar-
eas is needed in order to get a fuller picture
of the resident hoverfly populations. As
yet, many species of immigrating hover-
flies have not been caught in the Faroe Is-
lands, but with the right weather conditions
it should be possible. This is indicated by
our research in which at least 10 of the new
species found in the Faroe Islands were im-
migrants. The specimens are all kept at the
Faroese Museum of Natural History except
75 hoverflies belonging to H. N. Chris-
tensen (Denmark) and a small study collec-
