Lcihr, P.-W.: Hoverflies (Diptera, Syrphidae) from Malaise traps in Angermanland, coastal northern Sweden. [Blomflugor (Diptera, Syrphidae) tagna i Malaisefiillor vid Angerman- landskusten.l - ^Ent. Tidskr. 111:'79-82. UmeA, Sweden 1990. ISSN 0013-886x.

Hoverflies were collected lvith ^{Malaise traps} in 1979-1982 at AngerAn on the Bothnian coast

of the northem Swedish Angermanland province. In total, I 282 specimens of 85 species were identified. The four species P/arycfteirus perpallidas Verrall, l9ol, Parasyrphus mali- nel/us (Collin, 1952),Cheilosia rufimana Becker, 1894, and Eoseristalis picea (Fall6n, 1817) are reported from Sweden for the first time. An additional

¹

I species were not previously known from this region. Females dominated in the material. Flight periods are given for the ten most abundant species.

During the summers of 1979,1980 and 1982, in- sects were collected in bilateral Malaise traps by Em. Prof. K. Mtiller in NE Angermanland on the Swedish Bothnian coast. A part of the material of Syrphidae Eristalini and some other flies with chiefly aquatic larvae were reported on by Wagner (1981). I will here present a list of the rest, i.e.

the main part of the collected material of Syrphi- dae. As species distributions in Sweden are poorly known for this family, such a list provides many new records for the region and even for the coun- try.

Material and methods

Four Malaise traps were used close to the coastal stream AngerAn (63"35' N, 1950' E), about 30 km S of UmeA in the province Angermanland. In 1979, one trap was placed across the stream near the outlet in the Bothnian Sea, and in 1980 this trap was supplemented by one a bit north of the outlet, and one on an isle near the outlet. In ^1982, a single trap was used at Angerfjiirden, a small densely vegetated lake that the stream passes about 2 km from the outlet. A brief chemical and physical characterization of the stream and the

outlet bay was provided by Miiller & Mtiller- Haeckel (1978) and Mtiller & ^Mendl (1980). The vegetation of the outlet area was described by Dahlberg (1982).

The flies were collected in 50 7o glycol, trans- ferred to 70 Vo ethanol for preservation and later pinned and dried before examination. The identifi- cation followed mainly van der Goot ^(1981,

1986), and the nomenclature is from So6s & Papp

( 1988). The identification of the following genera benefitted from the cited works: Anasimyia (Claussen & Torp 1980), Brachyopa (Thompson 1980), ChrysoSasrer (Speight 1980), Melangyna (Nielsen l97l , ^1980), Metasyrphus (Du5ek & L6-

ska 1976), Neoascia (Barkemeyer & Claussen 1986), Platycfteiras (Nielsen 1971, 1974, 1981,

van der Linden 1986), Rhingia (Barkemeyer 1986), Sphaerophoria (Torp 1984), Syrphini

(Hippa 1968) Syrphus (Barendregt 1983), ^and Xylota (Andersson 1988).

The species identification was made proble- matic by the earlier conservation of the material in alcohol, and many specialists provided valuable help. A small proportion of the specimens could only be identified to genera.

List of species

For each species is given the total number of indi-

viduals of each sex collected in the four ^traps

during the three years. Species not previously re-

ported from Sweden are denoted with an S, and

those in which the range within Sweden is consid-

erably expanded with an A.

Comments to the species list

The material included 1388 specimens of Syrphi- dae, of which 1282 specimens were identified to species. In total, 85 species were recognized, and together with Wagner's (1981) records 93 species of Syrphidae are now known from the area. The dominance of females was recorded also by Wagner (1981) for tabanids and empidids.

Four species are here recorded from Sweden for the first time (Bartsch, in litt.). Platycheirus per-

pallidus Verrall, 1901, is considered rare or very rare (Torp 1984, Verlinden & Decleer 1987). It has been observed on sedges especially at margins of lakes, ponds and rivers (Stubbs & Falk 1983).

Three males were taken in the trap on the isle in 1980, and two males at Ängerfjärden in 1982.

Parasyrphus malinellus (Collin, 1952) is dif- ficult to separate from a few other species of the genus. It prefers forests, according to personal ob- servations especially spruce forests, also at the margins. Both females were taken near the outlet in 1980.

Cheilosia rufimana Becker, 1894, occurs in spring in moist forests. Torp (1984) observed it on flowers of Anthriscus sylvestris and Caltha palustris. Both females were taken in the stream trap in 1980.

Eoseristalis picea (Falla, 1817) was identified by Claussen after Kanervo's (1938) revision. It was not previously recorded from Sweden. E. pi- cea is sometimes listed as conspecific with E. ru- pium (Fabr.), but the distinct differences in genital shape have convinced me of its specific status.

The single female was taken in the stream trap in 1979.

Many species are here reported from the Ånger- manland province for the first time. However, only the 11 species for which the present records result in marked range expansions in Sweden (Bartsch, in litt.) were denoted with an Å.

The record of Xylota meigeniana is especially interesting as this species was recently mentioned from Sweden for the first time (Andersson 1988).

As these records were from South Sweden, the record from Ängerfjärden was unexpected. X.

meigeniana is normally very rare (Torp 1984) and easily mixed up with X. forum (Verlinden & De- cleer 1987). A qualitative analysis of the gut con- tents of a few individuals revealed pollens of gras- ses, Pinus and Epilobium.

More than half of all individuals belonged to the Melanostomatini, of which especially Mela- nostoma mellinum and Platycheirus clypeatus were very abundant. The flight periods of the ten most abundant species (Tab. 1), except X. meige- niana, largely agree with the information pre- sented by Wahlgren (1909) (Bartsch, in litt.).

Most species of the Melanostomatini have wide habitat preferences and occur in most biotopes.

Platycheirus scambus is, however, restricted to shores, and the larvae are aphidophagous. The two Xylota species and Cheilosia longula occur in for-
