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: 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.

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,...
