Species identification within the aphid genus Pemphigus Hartig, 1839 poses challenges due to morphological similarities and host-plant associations. Aphids of this genus generally exhibit complex life cycles involving primary hosts (poplars) and secondary (mostly unrelated herbaceous) host-plants, with some species relying solely on root-feeding ge...

Radzionków is a small town located in the central part of the Silesian Voivodeship. During three research seasons, conducted in 2019-2022, 100 species belonging to 16 orders of birds were found in Radzionków, among which 86 are strictly protected, eight are partially protected, and six are game species. 6 species are listed on the Red List of Birds...

In terms of body size, species of the genus Psyttala Stål, 1859, are the largest known representatives of the subfamily Reduviinae. Among the species belonging to this genus, Psyttala horrida (Stål, 1865) is the most popular, mainly because it is a laboratory breeding species. Individuals of this species were bred in the laboratory of the Zoology T...

Hybridisation is still a widely studied phenomenon that allows us to look at some processes differently. However, obtaining fertile hybrids, which we might consider in the long term as precursors of a new species, is still a field that requires research. Much of the research done so far indicates that hybrids are sterile – either sex or both. It is...

This paper presents a taxonomic revision and phylogenetic analysis of nine known species of the genus Phonoctonus Stål, 1853, distributed exclusively in the Afrotropical region. The revision and phylogenetic analysis were performed using morphological data. A full redescription for all species is provided, taxonomical problems are clarified, and di...

The Arctic aphids live briefly and must breed quickly to survive. Shortened life cycle, with only two generations: the stem-mother and sexuales—oviparous females and males is an adaptation for optimal use of the short breeding period, which lasts from late July to the end of August. Using Acyrthosiphon svalbardicum, an endemic High Arctic aphid spe...

We report for the first time the presence of the globally distributed and extremely polyphagous pest species — the crescent-marked lily aphid (or mottled arum aphid) (Neomyzus circumflexus L.) (Insecta, Hemiptera, Aphididae)—in Greenland. This species, of alien origin, was found on the ornamental plant Salix arbuscula L., imported from Denmark and...

Genus Platymeris Laporte, 1833 is a medium-sized genus belonging to the subfamily Reduviinae, and all known species of these assassin bugs are large-sized insects, distributed exclusively in Africa.

Although the high Arctic archipelago Svalbard is among the best-studied Arctic regions in terms of biodiversity, its aphid fauna is extremely limited. Two endemic species have been described to date, and no species of a foreign origin has been registered. Our observation is the first record of the non-native and potentially invasive green-peach aph...

At least a dozen species of aphids (Insecta, Hemiptera) of non-native origin have expanded their range in Europe, however the importance of botanic gardens in this phenomenon has not been studied previously in detail. As a case study, investigations on the species composition and host range of Aphidomorpha in the Royal Botanic Gardens, Kew, London,...

A total of...

During our previous morphological and molecular studies, as well as modelling the environmental niche preferences of the genus Sirthenea Spinola, 1840 (Peiratinae), the distribution of the species S. flavipes (Stål, 1855) became one of the most interesting issues. This species has a very broad distribution range covering the southern part of wester...
