We have observed seven species of predator beetles of the genus Bembidion in the agricultural landscape of the Leningrad Region (Northwestern Russia) between the years 2008 and 2018. These species reach their highest abundance in sun-exposed areas, especially mesophilic B. quadrimaculatum Linnaeus, 1761, B. properans (Stephens, 1828), B. lampros (Herbst, 1784), and B. femoratum Sturm, 1825. A few mesohygrophilic B. guttula (Fabricius, 1792) and B. gilvipes (Sturm, 1825) live primarily in areas of dense vegetation. Finally, the hygrophilic B. bruxellense (Wesmael, 1835) was only observed on the most humid soils. Assemblages of Bembidion ground beetles were separated in the fields, field boundaries, and adjacent habitats.

The article investigates the abundance of beetles of the genus Amara in the agrolandscape of the Leningrad Region. In the period from 2004 to 2010, 14 Amara species were collected by pitfall trapping. Amara fulva (O.F. Müll.) is the most common species in the potato and clean fallow fields, Amara similata (Gyll.) – in the grain and grasses fields, and A. communis (Pz.) ˗ in adjacent semi-natural habitats respectively. The cluster analysis shows that assemblages of ground beetles of the genus Amara in fields of different crops, field boundaries, and adjacent habitats are separated from each other. In the agrolandscape, the population of beetles of the genus Amara reaches its greatest species richness and abundance in perennial grassfields. In addition, to our best knowledge, this research was a first time when Amara ingenua (Duft.) was observed feeding on the flowering spikelets of timothy grass (Phleum pratense L.).

Corynephorus canescens (L.) P. Beauv. is a perennial grass of European origin, having a limited distribution in Russia. Previously, it was reliably reported from five administrative regions (i. e. the Bryansk, Kaliningrad, Moscow, Pskov and Smolensk Regions). In this article, I present the first record of C. canescens in the Leningrad Region (Northwestern Russia). The local population of the species was found in a natural habitat, a dry pine forest. This is the northernmost known locality of the species in Russia so far. The residence status of C. canescens in Northwestern Russia is briefly discussed.

The paper provides the first data on aphyllophoraceous fungi of the planned protected area «Kuznechnoye» (Kaarlahti) situated in Priozersk District of the Leningrad Region. The list includes 138 species annotated by data on their habitats, substrates, and frequency. Representative specimen numbers are cited for selected species. Hyphoderma incrustatum (first record in the European Russia), H. occidentale (first record in the northwestern Russia) and Junghuhnia semisupiniformis are recorded for the first time for the region. The specimens are kept in the Mycological herbarium of the Komarov Botanical Institute RAS (LE).
