Notes on the distribution and biology of Larinus sturnus (Schaller) in Finland (Coleoptera: Curculionidae)

Viramo, J. 2000: Havaintoja ohdakekärsäkkään (Larinus sturnus) levinneisyydestä ja elintavoista Suomessa [Notes on the distribution and biology of Larinus sturnus (Schaller) in Finland (Coleoptera: Curculionidae)]. - Sahlbergia 5:9-13.

Only one species of Larinus has been recorded in Finland and an earlier record on L. planus (F.) is based on misidentification. L. sturnus (Schaller) was observed living only in inflorescens of the Melancholy Thistle (Cirsium helenioides, syn. C. heterophyllum). The distribution of the weevil appeared to be much wider than previously suspected. The occurrence of the species should be made by checking the breeding sites rather than by searching for adult beetles. The present observations suggest considerable annual variation in abundance of the weevil.

Survey of the tree-living Coleoptera in Herttoniemi manor-park, southern Finland

Biström, O., Kaila, L. & Kullberg, J. 2000: Herttoniemen kartanopuiston puukovakuoriaisista (Coleoptera). [Survey of the tree-living Coleoptera in Herttoniemi manor-park, southern Finland]. - Sahlbergia 5:14-20.

The Coleoptera fauna living in old deciduous trees (elm, linden, maple, oak, birch) in the old manor-park of Herttoniemi situated in Helsinki, southern Finland, was surveyed in May-September 1996. Trunk-window-traps, pitfalls and trunk-pitfalls were used as collecting techniques. In all, 981 specimens belonging to 117 species were collected. Four nationally threatened species were recorded, viz. Quedius microps (Gravenhorst) (Staphylinidae), Eucnemis capucina Ahrens (Eucnemidae), Ampedus nigroflavus (Goeze) (Elateridae) and Tomoxia bucephala Costa (Mordellidae).

Macropis europaea Warncke, M. fulvipes (Fabricius) and their nest parasite Epeoloides coecutiens (Fabricius) in Finland

Pekkarinen, A., Albrecht, A., Teräs, I. & Viitasaari, M. 2000: Alpimehiläiset ja alpiloismehiläinen Suomessa [Macropis europaea Warncke, M. fulvipes (Fabricius) and their nest parasite Epeoloides coecutiens (Fabricius) in Finland] (Hymenoptera: Apoidea, Melittidae and Anthophoridae). - Sahlbergia 5:21-28.

Diagnostic characters and nesting biology of M. europaea and M. fulvipes are reviewed. Lysimachia vulgaris is the only natural pollen and fatty oil plant of these bees in Finland (they do not visit L. thyrsiflora), while almost 30 plant genera are recorded as nectar sources. Northernmost records of the two Macropis species approximately coincide with the limit of 60 % distribution frequency (weighted proportion of 1 x 1 km squares with records of all squares investigated) of L. vulgaris in Finland. The flight period of M. fulvipes is slightly earlier than that of M. europaea, but large phenological and spatial overlap indicate competition for pollen and oil resources. The records indicate no decline of M. fulvipes since 1970, but M. europaea has possibly declined in the northernmost part of its range already many decades ago. All records of E. coecutiens in Finland are since 1970.

Records of saproxylic insects (Coleoptera, Heteroptera and Homoptera) during one-day excursion to Sortavala area (Russian Karelia) in spring 1998

Martikainen, P. & Niemelä, P. 2000: Muistiinpanoja hyönteiskeräysretkeltä Sortavalan seudun metsiin keväällä 1998. [Records of saproxylic insects (Coleoptera, Heteroptera and Homoptera) during one-day excursion to Sortavala area (Russian Karelia) in spring 1998] - Sahlbergia 5:29-32.

The purpose of excursion was to demonstrate to forestry students the importance of coarse woody debris and forest structure on insect biodiversity. In spite of the early season (partial snow cover) altogether 60 forest insect species were recorded. Several species found are classified as threatened in Finland. At deciduous forest site, e.g. Drapetes mordelloides (Host), Mycetophagus quadripustulatus (Linnaeus) and Aradus pictus Bärensprung were recorded. Corticeus suturalis (Paykull) was found at mixed forest site. Acanthocinus griseus (Fabricius), Platyrhinus resinosus (Scopoli), Ampedus suecicus Palm, Aradus pictus, A. betulinus Fallén and Cixidia sp. were recorded at site which was burnt and clear cut. The results indicate that especially those species, which depend on coarse woody debris are still relatively common in Russian Karelia where forest management has not been as effective as in Finnish forests.

The mayfly Raptobaetopus tenellus (Albarda) from the Ruunaankoski rapids of River Lieksanjoki: a second record from Finland

Partanen, A. & Hämäläinen, H. 2000: Vuosurviainen, Raptobaetopus tenellus (Albarda) Lieksanjoen Ruunaankoskilta toista kertaa Suomesta. (Ephemeroptera: Baetidae). [The mayfly Raptobaetopus tenellus (Albarda) from the Ruunaankoski rapids of River Lieksanjoki: a second record from Finland] - Sahlbergia 5:33-34.

The mayfly Raptobaetopus tenellus is reported for the second time in Finland and Fennoscandia. The first and only hitherto known record, dated back to 1904, is from the shore of the river Kokemäenjoki in western Finland. In July 1999, a nymph of the species was collected from the river Lieksanjoki in the biological province of Karelia borealis, eastern Finland.

Maps of the provincial distribution of Neuroptera and Mecoptera in Finland

The distribution of Finnish Neuroptera (63 species) and Mecoptera (6 species) in biogeographical provinces is mapped. The faunistic literature including meeting reports dealing with Finnish material of those orders is listed.

Bembidion azurescens new to Finland

Westman, K, Kaila L., & Kullberg, J. 2000: Bembidion azurescens, Suomelle uusi maakiitäjäislaji (Coleoptera, Carabidae). [Bembidion azurescens new to Finland.] - Sahlbergia 5:39.

The ground beetle species Bembidion azurescens (Dalla Torre, 1877) is reported as new to Finland on the basis of some 30 individuals collected during 1984 - 1986 from a gravel pit in N: Helsinki. The site is now built and thus destroyed, but the species might still be found in suitable habitats along the south coast or East Finland.

The weevil Tropiphorus elevatus found in Kuopio (Coleoptera, Curculionidae)

Biström, O. & Savolainen, E. 2000: Tropiphorus elevatus -kärsäkäs löydetty Kuopiosta. [The weevil Tropiphorus elevatus found in Kuopio (Coleoptera, Curculionidae)]. - Sahlbergia 5:40.

A single specimen of the weevil Tropiphorus elevatus (Herbst) was recorded in Kuopio (Central Finland), the province of Sb (69746:5301, Grid 27° E). It was captured 11.-17.6.1999 in a window-trap placed on the ground in a grove with spruce as the dominating tree. This is by far the northernmost record of the species in Finland.

Notes on hoverfiles during the 20. Finnish Entomological Days at Jomala on Åland

Bartsch, H. 2000: Blomflugor under 20. finländska entomologidagarna i Jomala på Åland (Diptera, Syrphidae). [Notes on hoverfiles during the 20. Finnish Entomological Days at Jomala on Åland]. - Sahlbergia 5:41-45.

71 species of hoverflies (Diptera, Syrpidae) were netted during some sunny hours during four days in June 1999. Probably 200 species can easily be retrieved on the Åland islands, and extensive collecting may give up to 250 species. For some of these species, the Åland islands are essential for the communication between Finland and Sweden.

The male of Stylops recorded on Andrena lapponica Zetterstedt (Hymenoptera: Apoidea) in Finland

Vespula germanica found in the winter in southwestern Finland

Johansson, K. & Pekkarinen, A. 2000: Saksanampiainen (Vespula germanica) löytynyt talvella Turusta (Hymenoptera, Vespidae). [Vespula germanica found in the winter in southwestern Finland ]. - Sahlbergia 5:49.

A newly dead queen specimen of Vespula germanica (Fabr.) was found 25.3.1996 outdoors on the snow near the wall of a house of flats in Turku. An exceptionally early emergence in the spring is typical for the species and possibly delimitates its distribution in the boreal area.
