Notes on the occurrence of Gampsocoris Fuss, 1852 (Hemiptera: Heteroptera: Berytidae) in Poland

In Poland the genus Gampsocoris Fuss, 1852 is represented by two species: G. punctipes (Germar, 1822) and G. culicinus Seidenstücker, 1948. The paper presents new localities of both species, including the second record of G. culicinus in Poland. Additional information on their biology is provided. A possible immigration route of G. culicinus into Polish territory is discussed

Notes on the occurrence of Acetropis Fieber, 1858 (Hemiptera: Heteroptera: Miridae) in Poland, with a key to Polish species

In Poland the genus Acetropis Fieber, 1858 is represented by three species: A. carinata (Herrich-Schaeffer, 1841), A. gimmerthalii (Flor, 1860) and A. longirostris Puton, 1875. The paper presents illustrated key for the identification of mentioned species, new localities in Poland and the range of their distribution in Palaearctic Region. Additional information on the biology of all species is provided

New data on the occurrence of terrestrial true bugs (Hemiptera: Heteroptera) in Pieniny Mountains

The results on studies of the fauna of true bugs are presented. The research was conducted in the years 2005–2008 in the Pieniny Mountains. A list of 71 species, mainly belonging to the family Miridae, is presented. Among the identified specimens such rare species in Poland as Eurycolpus flaveolus, Stenodema sericans and Berytinus signoreti deserve a special interest. Features that distinguish very similar species, such as Lygus wagneri and L. punctatus, are given

New data on some rare planthoppers and leafhoppers in Poland (Hemiptera: Auchenorrhyncha)

This contribution presents new distribution data on nine rarely-collected species of planthopper and leafhopper in Poland: Pentastiridius beieri (Wagner, 1970), Asiraca clavicornis (Fabricius, 1794), Kelisia praecox Haupt, 1935, Stenocranus fuscovittatus (Stål, 1858), Aphrophora major Uhler, 1896, Stictocephala bisonia Kopp et Yonke, 1977, Handianus flavovarius (Herrich-Schäffer, 1835), Metalimnus steini (Fieber, 1869), and Sonronius dahlbomi (Zetterstedt, 1840). Distributional and ecological data are provided for each species

Terrestrial true bugs (Hemiptera: Heteroptera) of the upper Ropa river valley

99 species of terrestrial true bugs (Heteroptera) have been collected from the valley of upper Ropa river in the Estern Beskidy Mountains. Study has been taken during the two seasons: June – September 2010 and May – September 2011 and concerned various types of habitats, including beech forest and various types of meadows. The results showed the occurrence of rarely collected species (Adelphocoris ticinensis, Horistus orientalis, Metatropis rufescens, Stagonomus bipunctatus, Geocoris dispar and Polymerus microphthalmus) which are presented in detail. The study also presents the number of species in particular types of habitat and it demonstrates the possibility of migration of southern species through the Wysowska Pass

The occurence of Eysarcoris ventralis (Westwood, 1837) (Hemiptera: Pentatomidae) in Poland

Eysarcoris ventralis (Westwood, 1837) was found in Eastern Beskidy Mountains. The species is found for the first time in natural habita

Impact of warm weather events on prolongation of the life cycle of Stomaphis Walker (Hemiptera, Aphididae, Lachninae)

Termination of the life cycle of sexually reproducing aphids usually takes place in autumn, during October and November, in the climatic conditions of Central Europe. However, episodes of warm weather are suspected to trigger prolongation of the life cycle. Observations of Stomaphis spp. in early winter of 2013/2014 in southern Poland support this thesis. Surprisingly, adult females of two species were collected as late as early January and early March. High daily temperatures during this period were the probable cause of aphid survival, despite frosty nights. The possibility of the influence of warm weather episodes (higher temperature) on prolongation of the life cycle in aphids, or such episodes causing permanent parthenogenesis, is discussed

Materiały do znajomości chrząszczy z nadrodziny Scarabaeoidea Beskidu Wschodniego

The paper presents new data about distribution of Scarabaeoidea in the Eastern Beskid Mountains. The study was carried out in the area of south-western part of this region in the years 2003–2016. The total number of 24 species were recorded. Among the identified specimens such rare species as Ceruchus chrysomelinus and Aphodius scrutator deserve a special interest

Morphological study of the labial sensilla in Nabidae (Hemiptera: Heteroptera: Cimicomorpha)

The study presents new data on the morphology and distribution of the labial tip sensilla of six species of two nabid subfamilies— Protosteminae and Nabinae (Heteroptera: Cimicomorpha), which were obtained using a scanning electron microscope. In both taxa, there are five morphologically distinct types of sensilla on the tip of the labium: peg sensilla with a terminal pore, nonporous peg sensilla, elongated placoid sensilla with wall pores (multiporous), and trichoid sensilla. In addition, oval plate sensilla with a terminal pore (Tp-opls) were observed in the genus Himacerus. Campaniform sensilla and nonporous chaetic sensilla were observed on the surface of the last segment of the labium in all of the studied species. Over a dozen trichoid sensilla were scattered on the last segment of the labium only in the genus Prostemma. Based on their external structure, it is likely that these sensilla are chemosensitive and mechanosensitive. The oval plate sensilla with a Tp-opls (gustatory) in Himacerus (Nabinae) represent a morphological novelty that probably evolved independently of other nabids
