In order to study regional faunas, one or two methods of studying Coleoptera are often used. However, a comparison of several ways of studying shows that it is more expedient to use more than one of them. Six different methods of catching Coleoptera used in studies of the biodiversity of regional faunas were compared.

- * The dataset is significant, containing 4,826 georeferenced occurrence records along the Volga and Don River Basins, including a total of 17,373 studied individuals.
- * A total of 83 species of Neuroptera (across 8 families and 36 genera) and 4 species of Raphidioptera (from 2 families and 4 genera) were documented in the surveyed areas.
Studies on saproxylic species of Coleoptera have garnered significant attention due to the rarity of some of them. To investigate the distribution and biology of (Kraatz, 1880) (Scarabaeidae: Cetoniinae) in European Russia, we analyzed data from 16 regions collected between 2018 and 2024. This species has been reliably recorded in 26 regions.

- Long-term studies of plant populations reveal how environmental factors affect species, particularly edge-range species that are more likely to face extinction.
- The research focused on a plant population in the National Park "Smolny" in Russia from 2013 to 2018, assessing various individual plant parameters and density while identifying the ontogenetic structure.
- The findings indicated a shift from a vegetatively oriented population to a bimodal structure, correlating negative impacts on reproduction with weather conditions, and suggesting that habitat shading may adversely affect population health.
Usage of a variety of non-trivial ways to study Coleoptera gives unexpected and original results. The studies were conducted using simple traps with fermenting baits in the central part of European Russia. There were 286 trap exposures, and 7906 Coleoptera specimens (208 species from 35 families) were collected.
