New information about six species of cockroaches (Blattodea: Blatta orientalis L., Blattella germanica L., Ectobius lapponicus L., E. sylvestris Poda, Periplaneta americana L. and Phyllodromica maculata Schreber) and five species of earwigs (Dermaptera: Apterygida albipennis Megerle von Mühlfeld, Chelidurella acanthopygia Géné, Forficula auricularia L., Labia minor L. and Labidura riparia Pallas) found in the period of 1957–2021 in Poland are presented. In the case of four species, the first information about their presence in the particular geographical regions was provided, based on the Catalogue of Polish Fauna.

This paper presents the past and present occurrence of Mantis religiosa in Poland and discusses range changes of this species during the last 100 years (1923–2021), based on 2664 records, 2029 of these unpublished. Up to 1994, the species was restricted to a relatively small area in the south-eastern part of Poland (3.3% of the country's area). During 27 years (1995–2021), M. religiosa spread from there to the north, west and south, increasing its range more than 20 times, to 77% of Poland’s area. At present, only north-western part of the country and central part of mountainous belt in the south are not occupied or sparsely occupied by this species. The average annual increase in European mantis range in Poland in the years 2013–2021 was eight times faster than during the earlier period (1995–2012).

This paper presents the results of the study on grasshoppers and crickets (Orthoptera), earwigs (Dermaptera) and cockroaches (Blattodea) of the Bory Tucholskie National Park (=BTNP) (part of Tuchola Forest, northern Poland), conducted in the years 2001, 2013 and 2014. The insects were caught using Moericke traps at 9 sites, capturing respectively: 2001 – 11 ind., 2013 – 1115 ind. and 2014 – 228 ind. An additional visual record was made at the tenth site, where no traps were set. In total, 24 species of grasshoppers and crickets, 3 species of earwigs and 1 species of cockroach were recorded in the BTNP. Tettigonia cantans (Fuessly), Roeseliana roeselii (Hagenb.), Pholidoptera griseoaptera (Deg.), Chelidurella acanthopygia (Géné) and Labidura riparia (Pall.) were found for the first time within the whole Tuchola Forest. The research method used is noteworthy, as the capture of such a large number of orthopteroid insects in Moericke traps is rare in Poland.

This study summarises information on the occurrence of Myrmecophilus acervorum in Poland in the years 1851–2022. We collected information about 143 localities: 40 from literature and 103 unpublished. Myrmecophilus acervorum is reported from seven new regions: the Baltic Coast, Białowieża Primeval Forest, Eastern Sudety Mts, Kraków-Wieluń Upland, Podlasie Lowland, Sandomierska Lowland and Trzebnickie Hills. While until 2010 observations were rare (35 localities), in the years 2011–2022 the species was found in 108 new localities. A total of 443 individuals of M. acervorum were observed in Poland, but the sex was identified only for 138, of which 135 were mature females or female nymphs. Males were recorded only historically in the Pomeranian Lakeland. At present, these records should be treated with caution, as they are uncertain.

The report provides information about the occurrence of the house-cricket Acheta domesticus in 2021 in the area of the hard coal mines "Budryk" (Ornontowice) and "Pniówek" (Pawłowice). The species was recorded at depths of 900, 1050 and 1290 m ("Budryk") and 1050 m beneath the surface ("Pniówek"). The information provided testifies high adaptability of the species and encourages its search in other Polish mines.
