True bugs from Nagy-Hideg-hegy (Börzsöny) - results of the 20th Biodiversity Days
A new publication by Kondorosy Előd & Kóbor Péter: 'Poloskák a Nagy-Hideg-hegyről (Börzsöny): a XX. Biodiverzitás Napok eredményei - BioData Hungarica 3: 48-57. We recorded the source for the species in the Hungarian species list and applied the taxonomy used in the source.
The izeltlabuak.hu website primarily focuses on arthropods found in Hungary. This entry also deals with Hungarian fauna.

Summary
During the 20th Biodiversity Days, 127 species in 24 families were collected around Nagy-Hideg-hegy; a supplementary collection added 116 species (41 only then), so 168 species were recorded in total from the area.
Together with literature data, 189 species in 29 families from Börzsöny are documented by vouchers.
Citizen science data from iNaturalist and izeltlabuak.hu added 35 more species, so 224 species are now known from Börzsöny.
The species list includes several notable rarities. Some are known only from literature (Aradus brenskei, Palomena viridissima, Phimodera amblygonia, Rhacognathus punctatus).
Two mirid species are particularly significant finds. Excentricus planicornis was published from Hungary in 2025. The other novelty is the predatory mirid Macrolophus rubi, new to the fauna.
There are other rarities too, such as the Euro-Siberian lace bug Acalypta platycheila, the boreo-montane mirid Tytthus pygmaeus, and the lygaeid Megalonotus antennatus, though these are not sensational results.
