Dryinus niger Kieffer, 1904 ja Gonatopus solidus (Haupt, 1938), kaksi Suomelle uutta pihtipistiäistä (Hymenoptera: Chrysidoidea: Dryinidae)
Väänänen, S. & Vikberg, V. 2007: Dryinus niger Kieffer, 1904 ja Gonatopus solidus (Haupt, 1938), kaksi Suomelle uutta pihtipistiäistä (Hymenoptera: Chrysidoidea: Dryinidae). [Dryinus niger Kieffer, 1904 and Gonatopus solidus (Haupt, 1938) (Hymenoptera: Chrysidoidea: Dryinidae), two new dryinid speciesfound in Finland].– Sahlbergia 13: 1–5.
The dryinid wasps Dryinus niger Kieffer, 1904 and Gonatopus solidus (Haupt, 1938) are reportedfor the first time from Finland.Two females of D. niger were caught in a window trap in 6.7.-7.8. 2004 and 29.7.-1.9.2004 in St: Eurajoki. (6808:321). An another female was swept on 26.6.2006 in ES: Mikkeli (6848:528). D. niger represents a new dryinid genus and subfamily for Finland. D. niger is a parasitoid of adult leafhoppers (Homoptera: Auchenorrhyncha: Cixiidae). D. niger is a rare species and not much is known about its life-history or habits. Cixius cunicularius (Linnaeus, 1767) is tentatively named as a host for D. niger in Finland. Two females of G. solidus were swept on 5.8.1994 in U: Hanko (6641:277, leg. J. Perkiömäki). This rare speciesis new for Northern Europe. We also briefly discuss the evidence of Cixius nymphs (Cixiidae) being the probable hosts for Embolemus ruddii Westwood, 1833 (Hymenoptera: Chrysidoidea: Embolemidae).
Metanopedias lasiopterae (Kieffer, 1916) (Hymenoptera: Platygastridae) kasvatettu liekosääskestä Asynapta pectoralis Winnertz, 1853 (Diptera: Cecidomyiidae: Porricondylinae) Etelä-Suomessa
Vikberg, V. & Penttinen, J. 2007: Metanopedias lasiopterae (Kieffer, 1916) (Hymenoptera: Platygastridae) kasvatettu liekosääskestä Asynapta pectoralis Winnertz, 1853 (Diptera: Cecidomyiidae: Porricondylinae) Etelä-Suomessa [Metanopedias lasiopterae (Kieffer, 1916) (Hymenoptera: Platygastridae) reared from log midge Asynapta pectoralis Winnertz, 1853 (Diptera: Cecidomyiidae: Porricondylinae) in southern Finland]. – Sahlbergia 13: 6–9.
426 specimens of Metanopedias lasiopterae (Kieffer, 1916) were reared from a dead downy birch (Betula pubescens) branch intended for fire wood in Janakkala, Turenki in southern Finland. The platygastrid species emerged from cut ends of hard wood from radial cracks where the host log midge Asynapta pectoralis had its cocoons. This is the first rearing of M. lasiopterae from A. pectoralis and the first verified record of the larval biology of A. pectoralis.
Herhiläislyhytsiiven (Velleius dilatatus Fabricius; Coleoptera Staphylinidae) joukkoesiintyminen Kaakkois-Suomessa vuonna 2007
Biström, O. & Laiho, J. 2007: Herhiläislyhytsiiven (Velleius dilatatus Fabricius; Coleoptera Staphylinidae) joukkoesiintyminen Kaakkois-Suomessa vuonna 2007. (Mass-occurrence of the staphylinid species Velleius dilatatus Fabricius in South Eastern Finland in 2007 (Coleoptera)). – Sahlbergia 13: 10–12.
Numerous specimens of Velleius dilataus Fabricius, living as an accepted guest in the nest of the hornet (Vespa crabro Linnaeus), were collected in South Eastern Finland in the summer 2007. All records of the staphylinid species are listed and the findings since its first Finnsh record in 1999 to 2007 are mapped. The distribution of the hornet coincides remarkably well in comparison with records of V. dilatatus. As expected the occurrence of V. crabro seems to be a prerequisite for occurrence of V. dilatatus. V. dilatatus is at present a widely distributed species in South Eastern Finland.
Sudenkorentojen (Odonata) uudet maakuntahavainnot 2002–2007
Karjalainen, S. 2007: Sudenkorentojen (Odonata) uudet maakuntahavainnot 2002–2007 [New provincial records of Finnish dragonflies (Odonata) in 2002–2007]. – Sahlbergia 13: 13–25.
This paper presents 48 new provincial records of Finnish dragonflies made in 2002–2007. In this period two species new to the Finnish fauna have been found, viz. Aeshna mixta Latreille, 1805 and Sympecma paedisca (Brauer, 1877). By 2007, both of them are already distributed in a large area adjacent to the southern coast. Also Coenagrion puella (Linnaeus, 1758), Sympetrum sanguineum (Müller, 1764) and Leucorrhinia pectoralis (Charpentier, 1825) have become more common and are currently distributed in a wider area than before. The large number of new provincial records result from greatly increased interest in dragonflies in Finland and widened distribution pattern of some species. An updated version of a distribution table of Finnish dragonflies by biogeographical provinces is presented.
Edeltävän hellekesän entomologisia seurausilmiöitä alkukesällä 2007 Suomessa ja Latviassa (Odonata, Heteroptera, Hymenoptera, Lepidoptera ja Coleoptera)
Mikkola, K., Kaila, L., Rantala, M., Segersvärd, P. & Vuolanto, S. 2007: Edeltävän hellekesän entomologisia seurausilmiöitä alkukesällä 2007 Suomessa ja Latviassa (Odonata, Heteroptera, Hymenoptera, Lepidoptera ja Coleoptera) [Some entomological consequences of the exceptionally xerothermic summer 2006 shown in early season of 2007 in Finland and Latvia (Odonata, Heteroptera, Hymenoptera, Lepidoptera and Coleoptera)] – Sahlbergia 13: 26–33.
In southern and western Finland, the latter part of the summer of 2006 was extremely sunny and dry, and it was to be expected that some univoltine insect species would show gradations the next summer. As possible examples, the occurrences of five species from five different insect orders are presented. In the advantageous sunny weather of the early summer of 2007, the dragonfly Libellula quadrimaculata showed a mass eclosion in a shallow bay with vast reeds in SE Finland. The bug Graphosoma lineatum was for the first time encountered in a number, the first observation from the country being from the previous summer. The most dramatic mass occurrence was that of Dolichovespula media. In the early summer, a coastal migration of estimated 25 000 exx. was observed, and the numerous wasps caused troubles to the lepidopterists using bait traps. Worsening of the weather type probably prevented the queens to raise their progeny. The “free” lifespan of the non-oviposited queens extended as long as one and half months, but finally the wasps experienced a population crash. The noctuid Trachea atriplicis serves as an example of many nocturnal lepidopterans that were earlier rare but which came now in numbers to the baits. Finally, an exceptional migration obliquely against the wind along sea coast by the famous pest, colorado beetle, Leptinotarsa decemlineata, was observed in northern Latvia: around hundred specimens flew north and another hundred was found from the shore having drifted back with the waves.
Muutoksia Suomen kukkakärpäsfaunaan (Diptera, Syrphidae)
Haarto, A. & Kerppola, S. 2007: Muutoksia Suomen kukkakärpäsfaunaan (Diptera, Syrphidae) [Changes to Fauna of Finnish Hoverflies (Diptera, Syrphidae)]. – Sahlbergia 13: 34–40.
After the publication of Checklist of Finnish Hoverflies (Diptera, Syrphidae) (Haarto & Kerppola 2004) 24 species have been recorded as new to the Finnish fauna and four species have been omitted. Total number of species is now 350. Most of the newly recorded species are illustrated in the book ‘Finnish Hoverflies and some species in adjacent countries’ (Haarto & Kerppola 2007). The following species are here illustrated: Eupeodes goeldlini, Platycheirus urakawensis, Xanthogramma stackelbergi and Xylota xanthocnema.
Syspasis cutellator (Gravenhorst, 1829), Suomelle uusi kiho (Hymenoptera, Ichneumonidae, Ichneumoninae, Heresiarchini)
Koponen, M., Vainio, T., Vikberg, V. & Jussila, R. 2007: Syspasis scutellator (Gravenhorst, 1829), Suomelle uusi kiho (Hymenoptera, Ichneumonidae, Ichneumoninae, Heresiarchini). [Syspasis scutellator (Gravenhorst, 1829), new to Finland (Hymenoptera, Ichneumonidae, Ichneumoninae, Heresiarchini)]. – Sahlbergia 13: 41–43.
The ichneumonid species Syspasis scutellator is reported as a new species to Finland. It is fairly common from southern to middle Finland. A hibernating female was found and photographed. In summer the female has been found from May 31st to September 11th. The male has been found only from July 18th to August 28th. This species has not been reared in Finland.
Finnish Pipunculidae (Diptera) studies part II: an annotated checklist of Finnish big-headed flies
Kehlmaier C. & Ståhls G. 2007: Finnish Pipunculidae (Diptera) studies part II: an annotated checklist of Finnish big-headed flies.– Sahlbergia 13: 44–68.
The paper represents the second part of a project dealing with the Finnish Pipunculidae fauna. An annotated checklist is provided for Finland, with voucher specimens of each recorded taxon for each biogeographic region where present. The number of species cited for Finland is increased from 78 (including doubtful records) to 107.
