Idänkulkusirkan Locusta migratoria (L.) vaellus Suomeen kesällä 2010
Karjalainen, S. 2011: Idänkulkusirkan Locusta migratoria (L.) vaellus Suomeen kesällä 2010 [Migration of Locusta migratoria (L.) reached Finland in the summer of 2010]. – Sahlbergia 17(1): 4–7. Helsinki, Finland, ISSN 1237–3273.
A migration of Locusta migratoria (L.) reached Finland in the summer of 2010. More than 20 records were made in this summer, which more than doubles the records ever made in Finland. Most observations were made on the southern coast. The northernmost record was made near Oulu, in Siikajoki. L. migratoria was observed also in Sweden, Estonia, Latvia and Lithuania in 2010.
An interesting Cleruchus sp. (Hymenoptera: Mymaridae) from bracket fungi on aspen in Karelia, Russia
Triapitsyn, S. V., Vikberg, V. and Martikainen, P. 2011: An interesting Cleruchus sp. (Hymenoptera: Mymaridae) from bracket fungi on aspen in Karelia, Russia. – Sahlbergia 17(1): 8–10. Helsinki, Finland, ISSN 1237–3273.
A long series of a fairyfly wasp belonging to the genus Cleruchus (Hymenoptera Mymaridae) was collected from the bracket (polypore) fungi Trametes ochracea and Bjerkandera adusta on aspen, Populus tremula, in Kivach, Karelia, Russia. Taxonomic notes are provided on this species, whose female and male are illustrated. It is found to be very similar to, yet slightly different from, C. polypori from the Netherlands.
Kivatsun luonnonsuojelualueelta Venäjän Karjalasta kasvatettiin kahdesta kääpälajista (Trametes ochracea ja Bjerkandera adusta) haavan rungolta pitkä sarja Cleruchus -suvun hiukepistiäistä (Hymenoptera: Mymaridae). Tämän lajin taksonomiaa käsitellään artikkelissa ja lajin naaraasta ja koiraasta esitetään mikroskooppivalokuvia. Laji poikkeaa vain vähän aikaisemmin Hollannista kuvatusta lajista Cleruchus polypori.
Koivujungin ja punajungin kasvatuksia Etelä-Suomessa (Hymenoptera: Xiphydriidae)
Vikberg, V., Vilén, J. & Kakko, I. 2011: Koivujungin ja punajungin kasvatuksia Etelä-Suomessa (Rearings of Xiphydria camelus (Linnaeus) and X. prolongata (Geoffroy) in southern Finland) (Hymenoptera: Xiphydriidae). – Sahlbergia 17(1): 11–15. Helsinki, Finland, ISSN 1237–3273.
Xiphydriophagus meyerinckii (Ratzeburg) (Chalcidoidea: Pteromalidae) was reared in South Häme on eastern shore of the lake Päijänne from Xiphydria camelus. This is the second observation of the species and the first rearing in Finland. Xiphydria prolongata was reared in South Häme from Ulmus laevis, Salix pentandra and Salix caprea. It is a more common species in southern Finland than thought earlier. Near the Biological Station of Lammi many specimens were reared from old Salix caprea together with its parasitoid Coeloides rossicus (Kokujev) (Ichneumonoidea, Braconidae) of which 7 females 17 males emerged. This is the first rearing of the parasitoid in Finland, and only few females have been captured before in Finland.
Koivujungin kasvatuksesta Etelä-Hämeestä Päijänteen itärannalla syntyi 8 naarasta ja 6 koirasta kiilukaislajia Xiphydriophagus meyerinckii (Ratzeburg) (Chalcidoidea: Pteromalidae). Se on lajin toinen havainto ja ensimmäinen kasvatus Suomesta. Punajunki kasvatettiin Etelä-Hämeessä kynäjalavasta, halavasta ja raidasta. Se ei ole niin harvinainen laji jona sitä on pidetty. Lajista saatiin Lammin raitakasvatuksen yhteydessä vainopistiäisen Coeloides rossicus (Kokujev) 7 naarasta ja 17 koirasta. Tätä lajia ei ole aikaisemmin kasvatettu Suomessa ja kaikki aikaisemmat löydöt ovat olleet naaraita.
Malaise-rysillä kerätty näyte paarmoista ( Diptera: Tabanidae) Pohjois-Suomesta vuonna 2007
Laasonen, E.M., Laasonen, L. & Salmela J. 2011: Tabanidae (Diptera) from northern Finland caught by Malaise traps in the year 2007. – Sahlbergia 17(1): 16–21 Helsinki, Finland, ISSN 1237–3273.
Malaise traps were used to collect insect samples in 29 places in northern Finland. In all, 64 samples were available to studies for Tabanidae, and in 33 of them these flies were found and determined. A Table of these finds is presented, as this is to our knowledge the first systematic field survey of Finnish tabanids published. Virtually all the species determined are common in Finland, or at least common in Finnish Lapland like Hybomitra sexfasciata (Hine,1923). Even Chrysops sepulcralis (Fabricius,1794) and Hybomitra montana ssp. montana (Meigen, 1820) – earlier regarded as uncommon in Lapland – were well represented in this material. Hybomitra arpadi (Szilady,1923) was found as new for the biogeographical province Kainuu – Kn: Suomussalmi, Toskanoja 23.6 – 29.7 2007, 2 females. The placement of Malaise trap seems to be of utmost importance, when many of them did not catch Tabanidae at all, but the best trap caught 114 specimens. Perhaps the localities of Malaise traps were also very suitable for the two species mentioned, C. sepulcralis and H. m. montana.
Conura xanthostigma (Dalman, 1820) Suomessa (Hymenoptera, Chalcididae)
Koponen, M., Ketola, P., & Karhu, A. 2011: Conura xanthostigma (Dalman, 1820) Suomessa (Hymenoptera, Chalcididae). [Conura xanthostigma (Dalman, 1820) in Finland (Hymenoptera, Chalcididae)]. – Sahlbergia 17(1): 22–23. Helsinki, Finland, ISSN 1237–3273.
In the 2010 Red List of Finnish Species Conura xanthostigma (Dalman, 1820) is considered endangered (EN). In 2010 two new finds were made in Finland. These and all known previous finds are presented with text and a distribution map.
Hapsijäärän Necydalis major Linné (Coleoptera: Cerambycidae) kasvatuksia Etelä-Suomessa
Vikberg, V. & Vilén, J. 2011: Hapsijäärän kasvatuksia Etelä-Suomessa (Rearings of Necydalis major Linné (Coleoptera: Cerambycidae) in southern Finland. – Sahlbergia 17(1): 24–27. Helsinki, Finland, ISSN 1237–3273.
Specimens of the cerambycid species Necydalis major were reared in South Häme: Hämeenlinna, Aulanko from the trunk of a white willow (Salix alba), in South Savo: Lappeenranta, Monnonmäki from a rotten aspen (Populus tremula), and in Hämeenlinna, Lammi from the trunk of a small-leaved lime (Tilia cordata). One female and one male of Coleocentrus caligatus (Gravenhorst) (Hymenoptera: Ichneumonidae: Acaenitinae) were reared together with Necydalis major in Monnonmäki and Lammi respectively. These are the first rearings of this large ichneumonid from Necydalis.
Hapsijäärä kasvatettiin Hämeenlinnan Aulangolla valkosalavan rungosta, Lappeenrannan Monnonmäessä lahosta haavasta, ja Hämeenlinnan Lammilla metsälehmuksen rungosta. Monnonmäestä haapakasvatuksen yhteydessä hapsijäärän loisena kasvatettiin yksi loispistiäisen Coleocentrus caligatus (Gravenhorst) (Ichneumonidae: Acaenitinae) naaras. Lammin Biologisen aseman lehdosta metsälehmuksen rungosta kasvatettiin hapsijäärien ohella saman loispistiäisen yksi koiras. Nämä ovat ensimmäiset hapsijäärästä kasvatetut lajin yksilöt maailmassa. Koiras on ehkä Suomen ensimmäinen koiras.
Parasitoid wasps (Hymenoptera) reared from two polypore fungi on aspen in Kivach, the Karelian Republic of Russia
Vikberg, V. and Martikainen, P. 2011: Parasitoid wasps (Hymenoptera) reared from two polypore fungi on aspen in Kivach, the Karelian Republic of Russia. – Sahlbergia 17(1): 28–31. Helsinki, Finland, ISSN 1237–3273.
A sample of two polypore species (Trametes ochracea and Bjerkandera adusta) on aspen was taken on 21.5.1998 in Kivach, Karelia, Russia for rearing. Seven species of Coleoptera (Agathidium pisanum [Leiodidae], Orthoperus punctatus [Corylophidae], Cis boleti, C. submicans, C. fissicornis, Octotemnus glabriculus and Sulcacis fronticornis [Ciidae]) were obtained, and in addition seven species of small parasitoid wasps also emerged: two braconid species (Meteorus cis and Aphaereta scaptomyzae), two pteromalid species (Janssoniella sp. and Plutothrix sp.), one euderine eulophid species (Astichus sp.) and two mymarids (Camptoptera foersteri and Cleruchus sp.). All parasitoid wasps, except Aphaereta scaptomyzae, are previously known to be parasitoids on species of Ciidae.
Keväällä 1998 otettiin kasvatusta varten Kivatsun luonnonsuojelualueella Venäjän Karjalassa pinovyökääpä (Trametes ochracea)- ja tuhkakääpänäyte (Bjerkandera adusta) haavan rungolta. Kasvatuksessa syntyi seitsemän kovakuoriaislajia: Agathidium pisanum (Leiodidae), Orthoperus punctatus (Corylophidae) ja viisi kääpiäislajia: Cis boleti, C. submicans, C. fissicornis, Octotemnus glabriculus ja Sulcacis fronticornis (Ciidae) ja niiden ohella seitsemän loispistiäislajia: kaksi vainokaislajia (Meteorus cis ja Aphaereta scaptomyzae), kaksi pteromalidia (Janssoniella sp. ja Plutothrix sp.), yksi euderini (Astichus sp.) ja kaksi hiukepistiäistä (Camptoptera foersteri and Cleruchus sp.). Näistä 6 lajia on aiemmin todettu olevan kääpiäisten loisia ja yksi laji (Aphaereta scaptomyzae) elää pienten kärpästen toukissa.

The occurrence of Eutomostethus ephippium (Panzer) and E. nigrans (Konow) (Hymenoptera: Symphyta: Tenthredinidae) in Northern Europe
Vikberg V., Vårdal H., & Lønnve O.J. 2011: The occurrence of Eutomostethus ephippium (Panzer) and E. nigrans (Konow) (Hymenoptera: Symphyta: Tenthredinidae) in Northern Europe. – Sahlbergia 17(1): 56–78. Helsinki, Finland, ISSN 1237–3273.
The specimens of Eutomostethus ephippium (Panzer) and E. nigrans (Konow) were examined in Finnish, Norwegian and Swedish collections of sawflies, and data of them was gathered from Denmark, Lithuania, Latvia, Estonia and Russia. The occurrence of both species is shown in the 50-squares of the UTM grid maps. E. ephippium is widely distributed in North Europe: it is found in all studied countries. From Finland 778 females of E. ephippium were found. They are from the biogeographical provinces Åland, Varsinais-Suomi, Uusimaa, South Karelia, Satakunta, South Häme, South Savo, Ladoga Karelia, South Ostrobothnia, North Häme, North Savo, North Karelia, Central Ostrobothnia, Kainuu, Oulu Ostrobothnia and Koillismaa. Eutomostethus nigrans is found in Denmark (only old specimens in collections), Norway and Sweden. In addition one female of E. nigrans has been captured in Finland: Varsinais-Suomi, Raasepori, Fiskars, 25.6.1908 (leg. R. Frey). From Norway E. nigrans has been collected from 34 localities in 11 fylkes and its area appears larger than that of E. ephippium. The males recorded earlier from Norway could not be found, and their identification is possibly not correct; the male of the species is unknown. In Sweden the two species occur about equally frequently, and they have the same distribution area. E. ephippium is known from Skåne, Halland, Småland, Öland, Östergötland, Västergötland, Närke, Södermanland, Uppland, Dalarna, Gästrikland and Ångermanland. E. nigrans is known from Skåne, Småland, Gotland, Östergötland, Bohuslän, Närke, Södermanland, Uppland, Värmland, Dalarna, Gästrikland and Ångermanland. No males of either species were found in Finland and Sweden, and the earlier identified males proved to be misidentified and belonged to Stethomostus fuliginosus (Schrank) or S. funereus (Klug).

The local fauna of hoverflies (Diptera, Syrphidae) in the study area Helsinki Vanhankaupunginlahti and its fringe areas is presented. In total, 210 species have been recorded. This number represents almost 60 % of the total number, 357, of hoverfly species recorded in Finland. Nine species with photos included are new to the Finnish fauna: Pipiza festiva Meigen, 1822, Chrysogaster virescens Loew, 1854, Epistrophe diaphana (Zetterstedt, 1843), Epistrophe olgae Mutin, 1999 , Heringia latitarsis (Egger, 1865), Leucozona inopinata Doczal, 2000, Parasyrphus proximus Mutin, 1990 and Triglyphus primus Loew, 1840. Nine further species are redlisted species (Rassi eds. 2010) in Finland. Comments on some rare species are provided. They are marked by asterisk in Table 1.
Taxonomic notes on Caraphractus (Hymenoptera: Mymaridae)
Triapitsyn, S. V. Taxonomic notes on Caraphractus (Hymenoptera, Mymaridae). – Sahlbergia 17 (2): 20–29. ISSN 1237–3273.
Taxonomic notes on the Holarctic fairyfly genus Caraphractus Walker, 1846 (Hymenoptera: Chalcidoidea: Mymaridae) and its only recognized species C. cinctus Walker, 1846 are given. Caraphractus flavicollis Hellén, 1974 (Finland) is synonymized under C. cinctus. A lectotype is designated for C. reductus Rimsky-Korsakov, 1920, also a synonym of C. cinctus. Caraphractus hazomanitrae Risbec, 1952 (Madagascar), for which a lectotype is designated, is transferred to Acmopolynema Ogloblin, 1946 as A. hazomanitrae (Risbec), syn. n. Camptoptera perineti (Risbec, 1952) (Madagascar, originally described as Stichothrix perineti) is synonymized under A. hazomanitrae.
Kukkakärpäsiä (Diptera: Syrphidae) Malaise-rysin Pohjois-Suomesta vuonna 2007
Laasonen, E.M., Laasonen, L. & Salmela J. 2011: Syrphidae (Diptera) from northern Finland caught by Malaise traps in the year 2007. – Sahlbergia 17 (2): 30–37. ISSN 1237–3273.
Malaise traps were used to collect insect samples from 42 places – with two service visits each – in northern Finland from Kainuu to Inari Lapland. Syrphids occurred altogether in 60 samples, of which we determined 796 specimens representing 87 species. In comparable places with two visits most specimens, 70 % of the total catch, were observed during the first collection period from early June to about 20th July. Traps that were placed in the arcto-alpine region among alpine heaths and meadows, mountain birch forests or rich fens harbored most of the collected specimens. Syrphys ribesii (74 exx.) was dominant in the catches, followed by Parasyrphus tarsatus (70 exx.), Melanostoma scalare (65 exx.) and Scaeva selenitica (39 exx.). None of the species were present in all traps, Scaeva selenitica was found most often, in 16 traps, and 27 species occurred as singletons in the studied material. There were 12 new provincial records (KiL four, Kn four, Le two, InL one and PPe one record). Syrphids that were either abundant in the traps or new for any biogeographical province are regarded as rather common and widespread in northern Finland. Some Platycheirus species are held very rare in Finland. However, based on our findings and unpublished records entered into the database at Finnish Museum of Natural History, rarity of P. aeratus, P. latimanus, P. lundbecki, P. subordinatus, P. tarsalis, P. transfugus and P. varipes, should be re-evaluated.

Valenzuela gynapterus –lajista on löydetty lyhytsiipinen brachyptera –muoto ja Elipsocus –suvusta muoto E. cf. pumilis, jonka lajistatus on epäselvä. Lisäksi kerrotaan lajien Philotarsus parviceps Roesler ja Peripsocus consobrinus Pearman esiintymisestä Suomessa.
Nomada succincta Panzer, 1798 (Hymenoptera: Apidae), Suomelle uusi mesipistiäislaji Vantaalta
Salin, T. 2011: Nomada succincta Panzer, 1798 (Hymenoptera: Apidae), a wasp bee new to Finland. – Sahlbergia 17 (2): 46–51. ISSN 1237–3273.
Nomada succincta Panzer, 1798 is recorded from Finland for the first time. Three specimens (2 males, 1 female) were caught by a net in 2008 from Vantaa. Since then more than 100 specimens were recorded in a small area of eastern Vantaa during the summers of 2009-2011. Most likely the primary host of N. succincta in Finland is Andrena nigroaenea (Kirby, 1802). Individuals of the cleptoparasitic N. succincta were observed to participate the swarming of A. nigroaenea, probably to absorb the smell of the host. One likely copulation of N. succincta was also observed during the swarming event. Nomada goodeniana, a sibling species of N. succincta and earlier suspected to be conspecific with it, was not found among these swarming despite its abundance at the same area. This behavioural difference supports the validity of the species status of both these species.
