The arrangement is the same as previous years. All reports of interesting Microlepidoptera found and reported in 2022 or earlier, are validated by voucher specimens, by unambiguous photographs, or by the collectors/photographers, who have given relevant and reliable data for the records. Much information has been recovered from the Swedish portal “Species Observation System” https://www.artportalen.se or from related Facebook groups. During 2022 the weather significantly changed every month and occasionally reaching extremes during some periods. Like previous years, the winter of 2021/2022 was very mild with hardly any snow in the south, while the western and northern parts had almost normal precipitation. In the spring high pressure prevailed with many cold nights. In August–October a few warmer periods appeared with some immigration of particularly Macrolepidoptera.</p> <p>Seven species of Microlepidoptera have been recorded new to Sweden in 2022.</p> <p>1) <em>Caloptilia fidella</em> (Reutti, 1853) was found in Blekinge, Sölvesborg on 20 May.</p> <p>2) Two specimens of <em>Ypsolopha chazariella</em> (Mann, 1866) were attracted to light in Kista, Stockholm on 29 June and 1 July. The host <em>Acer tatarica</em> was growing close to the site.</p> <p>3) <em>Aristotelia bengtssoni</em> Gregersen &amp; Karsholt, 2022, with type locality in Gotland, Sweden, was recently described. This species has previously been noted as <em>Aristotelia</em> species (No. 1124 in Bengtsson m.fl (2016)). <em>A. bengtssoni</em> has also been recorded from Estonia (Gregersen &amp; Karsholt 2022: 244-246). The biology is unknown.</p> <p>4) <em>Batrachedra pinicolella</em> (Zeller, 1839) has been split into two species. The sibling species, <em>B. confusella</em> Berggren, Aarvik, Huemer, Lee &amp; Mutanen, 2021, has been recorded from Sweden i several provinces, as well as <em>pinicolella</em>.</p> <p>5) <em>Coleophora ballotella</em> (Fischer von Röslerstamm, 1839) was first observed in eastern Skåne where larval cases of the species were found on <em>Ballota nigra</em> in the end of May and imagines were later recorded in Skåne and Blekinge.</p> <p>6) <em>Blastobasis glandulella</em> (Riley, 1871). A male specimen was caught on light in the south of Skåne on 6 July and was verified by genitalia dissection.</p> <p>7) <em>Cnephasia pumicana</em> (Zeller, 1847) was also discovered in the south of Skåne in early July. Several male specimens were trapped on artificial pheromone designed for that species.</p> <p>Some other remarkable finds were made in 2022, as well. The extremely rare tineid <em>Agnatosia sandoeensis</em> Jonasson, 1977 was found in the province of Uppland during an investigation of insects bound to polypores. Two specimens hatched from a collection of <em>Amyloporia xantha</em> (Fr.) (Dahlberg 2023). <em>A. sandoeensis</em> is so far only known from the Swedish island Gotska Sandön in the middle of the Baltic Sea, Latvia (Šulcs 1979) and Austria (Gaedike 2015).</p> <p>A noticeable find of the tortricid <em>Cydia cornucopiae</em> (Tengström, 1869) was made in Lule lappmark far north of the hitherto known Swedish locality in Dalarna.</p> <p>Nomenclatural changes of species epithet, genus, etc., are presented under the heading “Intressantare arter och andra noteringar” [Interesting species and other remarks].</p> <p>Like in the previous years many species have extended their distribution area towards the north. Additional generations were recorded for many species, as well. Most Swedish lepidopterists have noticed a strong regression of the number of moths nowadays. A nightly trip 30–40 years ago rendered a soiled windshield by thousands of smashed insects. Now only a few spots appear after a similar trip. Apparently, the insect stock has been considerably reduced to similar extent as reported from other places in the world. The main reasons are most probably the excessive exploitation of natural forests and agricultural methods like applying monocultures and using insecticides and other chemicals. The biodiversity in all aspects is severely affected by these practices and are at long sight threatening food production and other important qualities in human life (Goulson 2021, Antonelli 2022).</p> <p>The number of recorded species of Microlepidoptera in Sweden is 1780.</p> Bengt Å.

In 2020, two specimens were caught in interception traps baited with pheromone, primarily placed out to catch <em>Platypus cylindrus</em> in oak stands. In 2021, two specimens were caught in a pitfall trap near oak logs placed out to support populations of <em>Lucanus cervus</em>. The distance between the most distant localities is 2,4 km. The findings indicate that <em>X. dryographus</em> is now established in Sweden. The number of known bark beetle species (Scolytinae) in Sweden is now 94.</p> Joel Hallqvist Mats Jonsell Åke Lindelöw Claud Youssif Stanislav Snäll Copyright (c) 2023 Entomologisk Tidskrift 2023-05-04 2023-05-04 144 1-2 21 28 Heliothis nubigera (Herrich-Schäffer, 1851) ett nytt nattfly för Sverige (Noctuidae, Lepidoptera) http://et-online.nu/index.php/contents/article/view/128 <p>The Eastern Bordered Straw <em>Heliothis nubigera</em> (Herrich-Schäffer, 1851) is reported from Näsby, Öland, Sweden. The first species for Sweden was collected by netting on flowers at dusk in August 27, 2022. The identification, biology, migration and distribution of <em>H. nubigera</em> are briefly discussed.</p> Henrik Lind Jesper Lind Copyright (c) 2023 Entomologisk Tidskrift 2023-05-04 2023-05-04 144 1-2 29 36 Recension: The Gelechiidae of North-West Europe - ett måste för varje småfjärilsintresserad! http://et-online.nu/index.php/contents/article/view/134 <p>Keld Gregersen har arbetat med att samla underlagen för denna bok i över 30 år och Ole Karsholt är en av världens kunnigaste experter på familjen Gelechiidae (palpmalar) som även av många fjärilsintresserade uppfattas som en ”besvärlig” grupp. Författarnas gedigna bakgrund, enorma arbetsinsats och entusiasm genomstrålar innehållet i denna massiva bok.</p> Nils Ryrholm Copyright (c) 2023 Entomologisk Tidskrift 2023-05-04 2023-05-04 144 1-2 37 38 Pentanota jani sp. n. upptäckt i norra Europa (Coleoptera, Staphylinidae, Aleocharinae) http://et-online.nu/index.php/contents/article/view/133 <p><em>Pentanota jani</em> <strong>sp. n.</strong> (Coleoptera, Staphylinidae, Aleocharinae, Oxypodini) is described from Finland. Formerly confused with the Siberian <em>Pentanota meuseli</em> Bernhauer and reported under this name, it is widespread in Finland and Sweden, and also present in Russian Karelia, Norway and Germany. Recent record of <em>Pentanota meuseli</em> from Poland very likely refers to <em>Pentanota jani</em>, as well. <em>Pentanota alpicola</em> Sawada is shown not to belong in <em>Pentanota</em> Bernhauer and it is provisionally regarded as <em>Neothetalia alpicola</em> (Sawada) <strong>new combination</strong>.</p> Jyrki Muona Copyright (c) 2023 Entomologisk Tidskrift 2023-05-04 2023-05-04 144 1-2 39 46 Rhipidothrips brunneus (Williams, 1913) (Thysanoptera: Aeolothripidae) ny art för Sverige, samt ett nytt landskapsfynd av Thrips menyanthidis Bagnall, 1923 (Thysanoptera: Thripidae) http://et-online.nu/index.php/contents/article/view/132 <p>Species in the order Thysanoptera, or thrips, are often overlooked, perhaps because of their small size and hidden biology. Even though some thrips species are broadly distributed in northern Europe, records in Sweden are lacking. This is also the case for the species <em>Rhipidothrips brunneus</em> (Williams, 1913), here presented with the first record for Sweden. <em>Thrips menyanthidis</em> Bagnall, 1923 is a species associated with <em>Menyanthes trifoliata</em> L. and was previously only known from one locality in Dalarna, but is here recorded for the first time from Värmland.</p> Emma Wahlberg Copyright (c) 2023 Entomologisk Tidskrift 2023-05-04 2023-05-04 144 1-2 47 51 Föreningsinformation http://et-online.nu/index.php/contents/article/view/131 <p>Sveriges entomologiska förening (SEF) är en riksorganisation för entomologiska föreningar i Sverige. Medlemmar i SEF är de föreningar som presenteras nedan. SEF har som uppgift att ge ut Entomologisk Tidskrift och att stimulera intresset för entomologi i Sverige, bland annat genom att stödja bildandet av insektsföreningar i nya områden.</p> Sveriges entomologiska förening Copyright (c) 2023 Entomologisk Tidskrift 2023-05-04 2023-05-04 144 1-2 52 54 Intressanta fynd av storfjärilar (Macrolepidoptera) i Sverige 2022 http://et-online.nu/index.php/contents/article/view/127 <p>This is the 50th consecutive annual report of new and interesting finds of Macrolepidoptera in Sweden, including a compilation of new provincial records; most of the new records are retrieved from personal reports and the Swedish Species Observation System https://www.artportalen.se. In 2022 two new species of Macrolepidoptera were recorded for the first time in Sweden: <em>Pungeleria capreoloaria</em> and <em>Heliothis nubigera</em>. A previously unseen number of individuals of the following migrating species reached Sweden in 2022: <em>Macroglossum stellatarum</em>, <em>Utetheisa pulchella</em>, <em>Isturgia arenacearia</em>, <em>Trichoplusia ni</em>, <em>Heliothis peltigera</em>, <em>Helicoverpa armigera</em>, and <em>Spodoptera exigua</em>. Examples of other migrating species not yet reproducing in Sweden recorded in Sweden in 2022 were <em>Amata phegea</em>, <em>Acherontia atropos</em>, <em>Euproctis chrysorrhoea</em>, <em>Orthonama obstipata</em>, <em>Catocala elocata</em>, <em>Hyssia cavernosa</em>, <em>Xylomoia graminea</em>, <em>Mythimna vitellina</em>, <em>Peridroma saucia</em>, <em>Agrotis bigramma</em>, <em>Euxoa ochrogaster</em> and <em>Autographa excelsa</em>. Species on their range limit, that might have populations reproducing in Sweden, recorded in 2022 were <em>Argynnis laodice</em>, <em>Scopula nigropunctata</em>, <em>Cyclophora annularia</em>, <em>Caradrina kadenii</em>, <em>Lacanobia splendens</em> and <em>Xestia ditrapezium</em>. In the warmer climate, many species continue to colonise new provinces and thus extend their ranges mainly northwards and inland in Sweden. Examples of such species are <em>Araschnia levana</em>, <em>Apatura ilia</em>, <em>A. iris</em>, <em>Callopistria juventina</em>, <em>Atethmia centrago</em>, <em>Conisania luteago</em>, <em>Nyctobrya muralis</em> and <em>Noctua interposita</em>. In contrast to species expanding their range margins, many other species are contracting their ranges due to intensified land use and habitat destruction, e.g. <em>Photedes captiuncula</em> and <em>Entephria caesiata</em>. The two critically endangered butterfly species, <em>Melitaea britomartis</em>, <em>Plebejus argyrognomon</em> and the endangered <em>Boloria polaris</em>, were not observed in Sweden in 2022 and might be extinct from Sweden. <em>Lithostege farinata</em>, recorded in 2021, could not be re-found in 2022. Also, many species connected to taiga forests, like <em>Baptria tibiale</em>, <em>Victrix umovii</em> and several northern <em>Xestia species</em>, are declining more or less strongly due to the intense industrial forestry. The total number of macrolepidoptera recorded in Sweden is now 1132, of which 16 are introduced.</p> Mats Lindeborg Markus Franzén Nils Ryrholm Copyright (c) 2023 Entomologisk Tidskrift 2023-05-04 2023-05-04 144 1-2 55 72 Släktet Gnathusa Fenyes (Coleoptera, Staphylinidae, Aleocharinae, Oxypodini) http://et-online.nu/index.php/contents/article/view/135 <p><em>Gnathusa</em> Fenyes, 1909 is shown to be the oldest available name for the junior homonym <em>Eurylophus</em> J. Sahlberg, 1876 nec Schönherr, 1836. Originally described from the Nearctic, <em>Gnathusa</em> is in fact a Holarctic genus with species in Norway, Sweden, Finland, Russia, China, USA and Canada. <em>Drepasiagonusa</em> Pace, 2012 is a junior subjective synonym of <em>Gnathusa</em> Fenyes, 1909. <em>Gnathusa feldmanni</em> (Assing, 2018) is regarded as a valid species, not a subjective junior synonym of <em>Gnathusa grandiceps</em> (J. Sahlberg, 1876). Six new combinations are presented: <em>Gnathusa angulata</em> (Assing, 2018) (Drepasiagonusa); <em>Gnathusa grandiceps</em> (J. Sahlberg, 1876) (Eurylophus); <em>Gnathusa feldmanni</em> (Assing, 2018) (<em>Drepasiagonusa</em>); <em>Gnathusa procera</em> (Assing, 2018) (<em>Drepasiagonusa</em>); <em>Gnathusa smetanai</em> (Pace, 2018) (<em>Drepasiagonusa</em>) and <em>Gnathusa tibetica</em> (Assing, 2018) (<em>Drepasiagonusa</em>). <em>Gnathusa seeversi</em> <strong>nomen novum</strong> is proposed for the secondary junior homonym <em>Gnathusa grandiceps</em> (Casey, 1911) [<em>Haploglossa</em>] not <em>Gnathusa grandiceps</em> (J. Sahlberg, 1876) [<em>Eurylophus</em>].</p> Jyrki Muona Copyright (c) 2023 Entomologisk Tidskrift 2023-05-04 2023-05-04 144 1-2 73 80
