Przyczynek do rozmieszczenia pluskwiaków różnoskrzydłych (Hemiptera: Heteroptera) w Polsce – IV

This paper continues a series of publications on the distribution of true bugs in Poland. It includes new faunistic data for 273 species of true bugs. In total, data on 33 species previously unreported in 14 zoogeographical regions of Poland are presented, including some rarely collected: Charagochilus spiralifer, Deraeocoris ventralis, Emblethis griseus, Emblethis denticollis, Liorhyssus hyalinus, Pyrrhocoris marginatus, Odontoscelis lineola, Stephanitis takeyai, Tytthus pygmaeus. Moreover, a food source, unusual for Pyrrhocoris apterus, was presented – the fresh carcass of a small rodent. It is also noteworthy that this paper was largely prepared using citizen science. Many people (non-specialists in Heterop-tera) collected data constituting almost 20% of the presented records. Notably, the true bugs recorded in this way include species very rarely collected in Poland and species alien to Polish fauna (e.g., Oxycarenus lavaterae and Halyomorpha halys). Due to the lack of funding being a significant obstacle to biodiversity studies in Poland, citizen science seems to be the only way to effectively monitor all the dynamic places in national entomofauna

[A contribution to the distribution of true bugs (Hemiptera: Heteroptera) in Poland – III]. This paper is a continuation of a series of publications on the distribution of true bugs in Poland and includes new faunistic data for 306 species of true bugs. In total, data on 62 species previously unreported in 21 zoogeographical regions of Poland is presented, including some rarely collected: Brachyarthrum limitatum, Eurydema fieberi, Peritrechus gracilicornis, Stephanitis pyri, Tingis crispata. It is also noteworthy that this paper was largely prepared using citizen science, where many people (non-specialists in Heteroptera) collected data constituting almost 25% of the presented records. Importantly, the true bugs recorded in this way include species very rarely collected in Poland, and species alien to Polish fauna (e.g. Oxycarenus lavaterae, Nezara viridula and Halyomorpha halys). Due to the lack of funding being a significant obstacle to biodiversity studies in Poland, citizen science seems to be the only way to effectively monitor all the dynamic changes taking place in national entomofauna

Corythucha ciliata (Say, 1832) i Arocatus longiceps (Stål, 1852) oraz inne pluskwiaki różnoskrzydłe (Hemiptera: Heteroptera) zimujące na platanach w południowo-wschodniej Polsce / Corythucha ciliata (Say, 1832) and Arocatus longiceps (Stål, 1852), as well as other true bugs (Hemiptera: Heterop-tera) overwintering on plane trees in south-eastern Poland

The paper presents the results of winter end early spring 2023 studies testing the use of the London planes for overwintering of true bugs. The study covered 317 plane trees at 174 separate sites within 100 10x10 km squares of the UTM network. Research sites were located within nine zoogeographical regions of southern and eastern Poland: the Eastern Beskids Mts., the Western Beskids Mts., the Sandomierz Lowland, the Roztocze, the Kraków-Wieluń Upland, the Lublin Upland, the Lesser Poland Upland, the Upper Silesia, and the Holly Cross Mts. Insects were sampled from the bark of trunks. As a result of the observations, for the first time in Poland, Dufouriellus ater - a representative of the Anthocoridae family was found wintering under the bark of the plane tree, which was not mentioned in any previous studies on this topic (Gil et al. 2011; Bury 2020; Hebda et al. 2020). Three invasive species were also detected: Corythucha ciliata, Arocatus longiceps, and Oxycarenus lavaterae. All of them may worsen the health of plane trees to varying degrees (Hebda et al. 2020). C. ciliata was the most frequently observed. The species was first recorded in Poland in 2009 in Lower Silesia (Lis B. 2009). In the current study, C. ciliata was found at 104 research sites within 55 UTM squares, including 40 new squares where this bug had not been detected before. In the remaining 15 squares, the presence of the species was confirmed at all previously known sites in this area (Czerniakowski and Olbrycht 2015; Bury 2020; Hebda et al. 2020; Gierlasiński et al. 2021). The species was first recorded in the Western Beskids, the Kraków-Wieluń Upland, and the Lesser Poland Upland. New observations support the thesis that the species' current main area of occurrence is the eastern and central part of Podkarpacie, where it most likely reached from the east via the Podolia route. The second, less numerous cluster of sites, discovered during this research, is located in western Małopolska and Upper Silesia, where the species could have reached from the south along the Moravian route. A. longiceps was detected at 24 research sites within 11 new UTM squares, where the species had not been recorded before. At the same time, the presence of the species could not be confirmed at three previously known sites in Łańcut, Zarzecze, and Wola Sękowa (Hebda et al. 2020). The species is still most abundant in the western part of the country (Gil et al. 2011; Hebda et al. 2020), but it was recorded for the first time in the Western Beskids Mts. and the Krakow-Wieluń Upland. Moreover, six new localities of the species were discovered in Upper Silesia, where previously it was known from one location in Strzelce Opolskie (Gierlasiński and Regner 2018). New observations support the ongoing expansion of this bug towards the east. O. lavaterae was detected at nine research sites within 9 UTM squares, including 4 new ones where the species had not been recorded. After the species was first recorded in Poland in Podkarpacie (Hebda and Olbrycht 2016), it quickly spread to western and then south-eastern Poland (Lis B. et al. 2019; Hebda et al. 2020; Bury et al. 2021). The new observations fit into the known area of occurrence of the species in south-eastern Poland. Of the remaining species, the most numerous were a representative of the Miridae family - Deraeocoris lutescens, observed at 16 research sites located within 15 UTM squares, and a representative of the Rhyparhochromidae family - Scolopostethus pictus, recorded at seven research sites in 5 UTM squares. Monitoring plane trees in south-eastern Poland for the presence of Hemiptera, particularly invasive species, should be continued
