Biström, O. & Pajunen, T.: Hiittisen kylän laidunniityn kovakuoriaiset ja hämähäkit Saaristomerellä kesällä 2023 (Coleoptera ja Araneae). — Sahlbergia 31(1): 2–11. Helsinki, Finland, ISSN 2342-7582.
A large pasture (about 10 ha) was studied during the summer 2023 (30.5-9.9.) regarding the fauna of beetles (Coleoptera) and spiders (Araneae). The sampling was undertaken in the Island of Hitis nearby the village of Hitisby (coordinates 6650:3249), in the province of Ab. Four combined pitfall and manure trap were constructed and dug in the ground separately from each other. In all 3584 Coleoptera specimens divided into 145 species and 599 spiders divided into 53 species were recorded. Nine species (eight Aphodius and Geotrupes stercorosus) are considered species bound to existence of cow dung on the pasture. Regarding spiders none is dependent of dung – they are considered secondary fauna dependent on dung looking for suitable prey as juveniles of insects. The total sample of insects and spiders caught are listed to species level in the Appendices. The specimens are preserved in the collection of the Finnish Museum of Natural History, Zoology unit (FMNH).
Mustonen, M. & Savin, J.: Maasiirojen (Isopoda: Oniscidea) suomenkielinen nimistö sekä täydennyksiä Suomen laji- ja maakuntaluetteloihin. — Sahlbergia 31(1):12–18. Helsinki, Finland, ISSN 2342-7582.
Viimeaikaiset lajikartoitukset sekä lukuisat kansalaishavainnot ovat lisänneet tietoamme Suomen maasiiralajiston nykytilasta. Suomalaisen maasiiratutkimuksen tueksi on laadittu ensimmäistä kertaa maamme lajiston kattava suomenkielinen nimistö. Tuoreiden havaintojen myötä on todettu lajien Philoscia muscorum ja Trichorhina tomentosa esiintyvän Suomessa. Lisäksi kymmenen muun lajin esiintymisestä ja levinneisyydestä Suomessa on kertynyt uutta tietoa. Monia maasiiralajeja tavataan aiempaa pohjoisempana ja uusia lajeja leviää ihmisen vaikutuksesta Suomen luontoon.
Recent field surveys and numerous citizen observations have increased our knowledge of the current status of Finland’s woodlouse species. For the first time, a Finnish nomenclature covering the species of Finland has been compiled to support the Finnish study of woodlice. Recent observations have led to the discovery of the species Philoscia muscorum and Trichorhina tomentosa in Finland. In addition, new information on the occurrence and distribution of ten other species in Finland has been collected. Many species of woodlice are being observed further north, and new species are being introduced into Finnish nature as a result of human activity.

Suomelle ilmoitetaan kolme uutta pikkuvaaksiaislajia (Diptera: Limoniidae): Dicranomyia chorea (Meigen, 1818), Dicranomyia megacauda Alexander, 1924 ja Neolimnophila alaskana (Alexander, 1924). Lisäksi raportoidaan viiden valtakunnallisesti merkittävän vaaksiaislajin uusista havainnoista (Diptera: Limoniidae, Tipulidae) vuosilta 2021-2024.
Three new species of Limoniidae (Diptera) to the Finnish fauna are reported: Dicranomyia chorea (Meigen, 1818), Dicranomyia megacauda Alexander, 1924 and Neolimnophila alaskana (Alexander, 1924). Nephrotoma relicta (Savchenko, 1973) and Nephrotoma quadristriata (Schummel, 1833) were found after about 40 years of break. Tipula subsignata Lackschewitz, 1933, a species recorded once from Finland during moth migration was recorded twice again in 2024, again during a moth migration. New records of another two very rare species Dicranomyia klefbecki (Tjeder, 1941) and Orimarga juvenilis (Zetterstedt, 1851) are reported as well.
Muinonen, A. & Vainikainen, J.: Kartioluteen Stethoconus cyrtopeltis (Flor, 1860) (Heteroptera, Miridae) esiintyminen Suomessa. — Sahlbergia 31(1):23–26. Helsinki, Finland, ISSN 2342-7582.
Miridae-heimoon kuuluva kartiolude Stethoconus cyrtopeltis (Flor, 1860) löytyi Suomesta ensimmäisen kerran vuonna 1947. Seuraavat havainnot tehtiin vuosina 2007 ja 2013. Vuosina 2019-2024 kartiolude on löytynyt 22 uudesta paikasta laajalla alueella painottuen Itä-Suomeen. Tässä artikkelissa esitellään kaikki havainnot. Kartiolude käyttää ravinnokseen varpuluteitaStephanitis oberti (Kolenati, 1857) ja elää etenkin kangasmetsissä sekä rämeillä. Aiempien kirjallisuustietojen pohjalta artikkelissa käydään läpi kartioluteen erot sen eurooppalaiseen lähilajiin Stethoconus pyri (Mella, 1869).
Stethoconus cyrtopeltis (Flor, 1860), belonging to the family Miridae, was found in Finland for the first time in 1947. The following observations were made in 2007 and 2013. In 2019-2024, Stethoconus cyrtopeltis has been found in 22 new places, mostly in eastern Finland. This article presents all the findings. Stethoconus cyrtopeltis feeds on Stephanitis oberti (Kolenati, 1857) and lives especially in coniferous forests and wooded swamps. Based on previous literature, the article reviews the differences between Stethoconus cyrtopeltis and its European relative, Stethoconus pyri (Mella, 1869).
Vikberg, V. 2025: Melanagromyza verbasci Spencer, 1957 kasvatettu Suomessa ukontulikukan varsista [Melanagromyza verbasci reared in Finland from stems of Verbascum thapsus] (Diptera: Agromyzidae). — Sahlbergia 31(2):2–3. Helsinki, Finland, ISSN 2342-7582.
Melanagromyza verbasci was reared in Janakkala in southern Finland from stems of Verbascum thapsus in 1996, 1997 and 2025 as a new species for Finland. Chlorocytus longicauda and Syntomopus incurvus (Pteromalidae) were reared as its parasitoids for the first time. The unknown male of Chlorocytus longicauda was reared for the first time. Chlorocytus longicauda has been reared earlier in Finland from Melanagromyza angeliciphaga in stems of Angelica sylvestris in Nurmijärvi, Hämeenlinna, Janakkala and Mikkeli.
Tammsoo, C., Kesküla, T. & Kurina, O. 2025: Fleas of Estonia: a taxonomic checklist (Insecta: Siphonaptera). — Sahlbergia 31(2):4–7. Helsinki, Finland, ISSN 2342-7582.
Data on Estonian Siphonaptera have been scattered across various old and obscure publications, making them largely inaccessible to a wider international audience. We present an up-to-date, literature-based checklist of 38 Siphonaptera species occurring in Estonia.
Komonen, A. & Ritari, E. 2025: Luteiden, muurahaisten ja maakiitäjäisten runsaus perinneympäristöissä ja tienpientareilla Keski-Suomessa. — Sahlbergia 31(2):8–14. Helsinki, Finland, ISSN 2342-7582.
Perinneympäristöt ovat tärkeitä selkärangattomien elinympäristöjä. Myös muut ihmisen ylläpitämät ympäristöt, kuten tienpientareet, voivat tarjota selkärangattomille elinpaikkoja. Selvitimme perinneympäristöjen (hoidetut niityt ja laitumet) ja tienpientareiden lude-, maakiitäjäis- ja muurahaislajistoa Keski-Suomessa 2014. Suurimmat yksilömäärät saatiin niityiltä. Lajimäärät olivat melko samansuuruisia eri elinympäristötyypeissä. Lajeista 36–46 % esiintyi kaikissa kolmessa elinympäristötyypissä. Uhanalaisia lajeja ei havaittu.
Traditional rural biotopes are important habitats for invertebrates. Also other human-maintained environments, such as road verges, can provide habitats for invertebrates. We studied the species composition of true bugs, ground beetles and ants in traditional rural biotopes (managed meadows and pastures) and road verges in Central Finland in 2014. The largest numbers of individuals were found in meadows. The number of species was similar in different habitat types. 36–46% of the species occurred in all three habitat types. No endangered species were observed.
Yrjölä, V. 2025: Muutoksia Suomen Spilomicrini Ashmead, 1893 (Hymenoptera: Diapriidae) lajien luetteloon. — Sahlbergia 31(2):15–18. Helsinki, Finland, ISSN 2342-7582.
An annotated checklist of the Spilomicrini Ashmead, 1893 (Hymenoptera: Diapriidae) of Finland is provided after over 60 years of the last assessment. Ten new species are added, and three species are removed due to misidentifications. As a result, the Finnish list now totals five species of Entomacis, two species of Idiotypa, four species of Paramesius and 14 species of Spilomicrus. Additional sampling is needed in the future to produce a more solid checklist.
Vikberg, V., Koponen, M. & Paukkunen, J. 2025: Megastigmus and Torymus species associated with berries of Sorbus aucuparia and Amelanchier spicata in Finland (Hymenoptera: Chalcidoidea, Megastigmidae and Torymidae). — Sahlbergia 31(2): 19–27. Helsinki, Finland, ISSN 2342-7582.
The Nearctic species Megastigmus amelanchieris and Torymus aea are reported from South Finland. They were collected from berries of Amelanchier spicata in Janakkala in 2019–2024. In Finland the first females of M. amelanchieris were captured already in 1976 in Nurmijärvi and Lammi, but were overlooked previously. Their characters are described and they are compared with closely related species Megastigmus brevicaudis reared from berries of Sorbus aucuparia and A. spicata, and Torymus aucupariae swept on berries of S. aucuparia. The male of M. brevicaudis is described. Torymus druparum was collected from berries of A. spicata in Janakkala.
