Here, we present the latest findings on moth fly (Psychodidae: Diptera) species richness in the Moravskoslezské Beskydy Mts. and Podbeskydská Pahorkatina Uplands, based on both previously published and unpublished data and new samples collected between 2007 and 2020. Two species new to the fauna of the Czech Republic were recorded (Sycorax feuerborni Jung, 1954 and Jungiella (Jungiella) revelica Vaillant, 1972), bringing the total number of moth fly species in the Czech Republic to 180 (Ježek et al. 2021). In addition, five species were recorded for the first time in the area of interest: Trichomyia parvula Szabó, 1960 (second locality in the Czech Republic); Paramormia (Phyllotelmatoscopus) acuta (Krek, 1971) (third record in the Czech Republic); Philosepedon (Philosepedon) perdecorum Omelková & Ježek, 2012 (third locality and fourth record); Pericoma (Pericoma) ljubiniensis Krek, 1969 (second finding and third locality); Tonnoiriella pulchra (Eaton, 1893) (sixth area and first finding in the Czech Carpathians). The finding of Jungiella (Jungiella) valachica (Vaillant, 1963) confirms its historical occurrence in the region. In the latest survey, we collected 108 species from 29 localities, of which 16 are critically endangered, eight endangered and three vulnerable. Nine localities were evaluated as species-rich, i.e. Hluchý 1. (58 species), Vysutý 2. (56), Hluchý 2. (53), Vysutý 4. (49), Skalická Morávka 2. (46), Chladná voda 3. (44), Hluchý 3. (43), Morávka - spring and Obidová 1. (both 42). The total number of moth flies found within the Moravskoslezské Beskydy Mts. and Podbeskydská pahorkatina Uplands now stands at 124 species, representing 68.9 % of total Czech fauna.

Publications up to 2011 record 21 species of stonefly, infraorder Systellognatha, as occurring in the Moravskoslezské Beskydy Mts. and Podbeskydská pahorkatina Uplands; however, seven of these cannot be considered part of the fauna of this area as they probably never occurred there, and one species (Perla abdominalis Burmeister, 1839) was not confirmed, despite being demonstrably recorded in 2000. In the present study, the current stonefly fauna was confirmed at 14 species, belonging to three families and eight genera. The occurrence of Isoperla sudetica (Kolenati, 1859) is published for the first time. Among the most important findings are confirmation of the occurrence of two endangered species (Perla grandis (Rambur, 1841) and Arcynopteryx dichroa (McLachlan, 1872)) and one near threatened species (Isoperla buresi Raušer, 1962). Equally important is confirmation of the occurrence of Perlodes intricatus (Pictet, 1841), based on egg morphology and DNA barcoding.

Based on voucher adult specimens of Agromyzidae (Diptera) faunistic records of 23 species are given all of which are new additions to the fauna of the Netherlands. With this addition a total of 265 species of Agromyzidae are currently known from the country.

In this study are presented six cases of abnormal behaviour based on injured individuals of Mus spicilegus from northern border of the species’ range. The material consistent of six individuals caught during autumn-winter season 2020 in field biotope on south-eastern Slovakia. Determination by morphological traits and subsequent dissection confirmed that all trapped mice were subadults. The cause of the damage found in distinctly bite was aggressive behaviour by other individuals or selfmutilation. There were three main types of damage: (1) incomplete infanticide (2) cannibalism and finally (3) self-mutilation. The findings presented in this study display the first documented abnormal behaviour in the mound-building mouse obtained in the wild.
