Special Issue Information

Dear Colleagues,

Coleoptera, commonly known as beetles, represent the largest order in the animal kingdom, with over 400,000 described species—accounting for approximately 25% of all known life forms. With their diverse morphologies and species richness, beetles occupy almost every terrestrial and freshwater niche, playing vital functional roles in these ecosystems. As decomposers, herbivores, predators, and pollinators, beetles are of paramount importance to ecosystem functions, agriculture, and forestry. However, this massive group is facing increasing threats from habitat loss, climate change, and declining biodiversity. Consequently, there is an urgent need for a deeper understanding of the mechanisms underlying beetle diversity, including its influencing factors and effective conservation strategies.

We cordially invite researchers to contribute to this Special Issue to collectively advance our knowledge of beetle diversity. This Special Issue welcomes original research articles, reviews, and short communications covering all aspects of beetle diversity. Topics of interest include, but are not limited to, the following: taxonomic discoveries and systematics; phylogeny and evolutionary relationships; biogeography and ecological drivers of diversity; functional trait diversity; responses to environmental change; assessment of conservation status and sustainable strategies; the application of novel technologies and methods in beetle research (e.g., environmental DNA, genomics).

The nemoral biome encompasses some of the most diverse and productive ecosystems in Europe, yet it has been extensively transformed by human activity. The capacity of secondary forests that have developed on sites of clear-cut broadleaved forests to sustain ground beetle diversity remains insufficiently studied. Ground beetles were sampled using pitfall traps during May–July in 21 post-logging forest stands across six administrative regions of Central Russia. A total of 90 ground beetle species were recorded. The superdominant species in most habitats were Carabus cancellatus Ill. and Pterostichus melanarius Ill. The median species richness per sampling plot was 17, and the median activity density was 33.6 individuals per 100 trap-days. The similarity of ground beetle assemblages, in terms of both species composition and community structure, is determined primarily by habitat characteristics rather than by the spatial proximity of sampling sites. The most robust predictor of both species composition and community structure was the percentage cover of Corylus avellana. A large proportion of exposed soil within forest stands is associated with a higher activity density of mixophytophagous stratohortobionts, predominantly Harpalus rufipes L. As the distance from large forest tracts increased, the activity density of large walking epigeobiont zoophages declined. Overall, the species structure of ground beetle assemblages was only weakly predictable. Full article

A comprehensive annotated checklist of the members of the phytophagous ladybird beetle tribe Epilachnini (Coccinellinae) in China is compiled based on existing published sources and incorporates the latest taxonomic and nomenclatural updates. The checklist documents 176 extant species across 10 genera and provides analyses of regional species richness, distribution, and host plant associations. Regarding regional species richness, Yunnan Province is home to the highest number of species (76), followed by Taiwan (50), Sichuan (48), Guizhou (48), Guangxi (43), Tibet (43), Guangdong (25), Hainan (17), Hubei (17), Hunan (13), Shaanxi (13), Fujian (12), Henan (10), Jiangsu (10), Anhui (7), Shandong (7), Zhejiang (7), Jiangxi (5), Hong Kong (5), Gansu (5), Beijing (4), Hebei (4), Liaoning (3), Shanxi (2), and Chongqing, Jilin, Heilongjiang, Ningxia, and Xinjiang (each with one species). Among the recognized genera, Epilachna Chevrolat, 1837, is currently the most species-rich genera, with 59 species, followed by Afissa Dieke, 1947 (34), Uniparodentata Wang & Cao, 1993 (28), Henosepilachna Li, 1961 (29), Afidentula Kapur, 1958 (10), Diekeana Tomaszewska & Szawaryn, 2015 (9), and Epiverta Dieke, 1947 (4). Additionally, Afidenta Dieke, 1947, Cynegetis Chevrolat, 1837, and Subcoccinella Agassiz & Erichson, 1845 are each represented by a single species. Host plant data are currently available for only 72 species (approximately 41% of the species recorded in China), which are associated with 177 plant species across 34 families. The most frequently recorded host plant families are Solanaceae (43 species), Cucurbitaceae (32), Urticaceae (15), Fabaceae (14), Asteraceae (14), and Poaceae (10), whereas each of the remaining 28 families comprises fewer than 10 host species. For 104 species (59% of the Chinese members of the tribe), host plant associations remain unknown, highlighting a substantial gap in our understanding of their feeding habits. Full article
