Record of the longhorn beetle Xylotrechus pantherinus (Savenius, 1825) at the former military training area Krnov-Chomýž (northern Moravia, Czech Republic)Articles
Lukáš Spitzer, Josef Kašák
Acta Carp. Occ. 16: 172-177, 2025 | DOI: 10.62317/aco.2025.009
Former military areas and training grounds host valuable fauna that would otherwise face extinction in the current central european landscape. Over the past decades, these habitats have suffered from overgrowth, but many are now managed through mowing or extensive grazing by large herbivores. This report provides information on an interesting record of the one adult specimen of endangered longhorned beetle Xylotrechus pantherinus (Savenius, 1825) from the former military area Krnov-Chomýž (Krnov District, Czech Republic) in 2023, which is now managed mainly through by grazing of aurochs and semi-wild Exmoor ponies.

Acta Carp. Occ. 16: 167-171, 2025 | DOI: 10.62317/aco.2025.008
This paper summarizes new records of endangered species Arctia aulica (the Brown Tiger Moth) (Erebidae: Arctiinae) from the Moravian Wallachia Region, central Moravia (Czech Republic). The species was recorded at six localities within the faunistic grid system (6674: Halenkov-Lušová; 6675: Halenkov-Břežitá; 6673: Podkopná Lhota-Humenec, Ratiboř and Vsetín-Semetín; 6474: Krhová) between 2014 and 2025. The records are based on observations of adults or larvae. Findings come partly from recently abandoned or extensively grazed pastures or their surroundings, such as the edges of forest clearings. The low number of records, despite relatively intensive...
The orb-weaver Gibbaranea ullrichi (Araneae: Araneidae) and other new significant records from the Váté Písky National Natural MonumentArticles
Kryštof Rückl, Václav Kroc
Acta Carp. Occ. 16: 162-166, 2025 | DOI: 10.62317/aco.2025.007
At the Váté Písky National Nature Monument, a population of the orb-weaver Gibbaranea ullrichi was recorded. This rare species can be overlooked due to living low above ground among sparse vegetation. The nocturnal collection using a torch seems to be suitable for recording many individuals of G. ullrichi. Trichoncoides piscator, Taranucnus setosus, Araniella inconspicua and Diaea livens are other rare species found for the first time at this locality.

The Kosteliska Bird Park is a private protected area covering of 112 hectares, established primarily for the purpose of bird protection. It is located in the floodplain of the Kyjovka River north of the Jarohněvický rybník pond near the town of Dubňany (Hodonín district, south-eastern Moravia). A mosaic of water bodies, reed beds, meadows, forests and sandbanks of a steppe nature occures here. Such a diverse environment is of great value from a conservation point of view, as it offers a wide array of habitats and supports exceptionally rich biodiversity. An inventory survey focused on water beetles was conducted between 2020 and 2024....

Acta Carp. Occ. 16: 1-11, 2025 | DOI: 10.62317/aco.2025.001
Populations of forest rodents change their structure and density depending on environmental conditions, causing variations in their fossorial activity and burrow distribution. Research conducted over two years focused on forest rodent species, Apodemus flavicollis and Myodes glareolus. A correlation was recorded between rodent clustering and the aggregation of burrow openings in systems located in plots with a significantly higher representation of European beech (Fagus sylvatica). Plots with scattered oaks (Quercus spp.) were intensively used by forest rodents. This tree species provides numerous cavities widely used...

Pseudognaphalium luteoalbum in the Hostýnské vrchy Mts after more than 100 years
(eastern Moravia, Czech Republic)Articles
Pavel Dřevojan
Acta Carp. Occ. 15: 31-35, 2024 | DOI: 10.62317/aco.2024.009
The article discusses the discovery of the critically endangered species Pseudognaphalium luteoalbum at a new locality in the Hostýnské vrchy Mts, where it was last recorded more than 100 years ago. Its population is very numerous, consisting of several hundred individuals. The species occurs in a sparse spruce plantation. The vegetation where Pseudognaphalium luteoalbum grows was documented through a phytocoenological relevé, and its species composition is commented on. Activities related to timber harvesting appear to be an important factor for the species survival in forested areas. For Pseudognaphalium luteoalbum as a winter-annual...

Acta Carp. Occ. 15: 25-30, 2024 | DOI: 10.62317/aco.2024.008
Records of the ladybird Tetrabrachys connatus (Panzer, 1796) from the Czech Republic are summarised based on the study of private collections and published data. It is a rare species in Central Europe. In the Czech Republic it is recently known so far only from a few localities in the South Moravian Region, concentrated in the Pálava Protected Landscape Area. The paper also summarises literature and unpublished data from more than 20 new localities in the Czech Republic from 16 faunistic squares, including the northern-most record from Central Moravia. Most specimens were collected by sifting or pitfall traps in dry grasslands on calcareous or loess soils.

Acta Carp. Occ. 15: 8-17, 2024 | DOI: 10.62317/aco.2024.002
The distribution of the rare assassin bug (Peirates hybridus) in the Czech Republic underwent significant changes during the 20th and 21st centuries. The species disappeared from the territory in the mid-20th century, but has recently recolonised it and rapidly spread beyond its original range. The species was rediscovered in Moravia after 50 years (in 1998), and after more than 100 years also in Bohemia (in 2021). At the start of the 21st century, it rapidly spread through the valleys of large rivers and into previously inhabited areas. The expansion of the species is likely due to a combination of factors related to climate change. Historically,...
