“…Diversity patterns of phytophagous beetles are known to be generally linked to species turnover of their host plants (Kemp et al, 2017; Luo et al, 2021; Ødegaard, 2006) and their distribution is correlated with the region and forest type (Yotkham et al, 2021). Other guilds, such as dung‐feeding beetles, respond to shade cover rather than plant species composition.…”

Very little is known about factors determining the assemblage structure of megadiverse polyphagous‐herbivore scarab chafers in the tropics (Coleoptera: Scarabaeidae). Here, we examined the composition of Sri Lankan chafer assemblages and investigated whether it is influenced more by the general ecoclimatic situation, macrohabitat, or indetermined stochastic biotic and abiotic factors of each locality. We also explored the influence of the latter on separate lineages and general body size. Based on dedicated field surveys conducted during the dry and wet seasons, we examined 4847 chafer individuals of 105 species sampled using multiple UV‐light traps in 11 localities covering different forest types and altitudinal zones. Assemblages were assessed for compositional similarity, species diversity, and abundance within four major eco‐spatial partitions: forest types, elevational zones, localities, and macrohabitats. Our results revealed that assemblages were shaped mainly by locality stochastics (i.e., multi‐factor ensemble of all biotic and abiotic environmental conditions at local scale), and to a minor extent by ecoclimatic conditions. Macrohabitat had little effect on the assemblage composition. This was true for the entire chafer assemblage as well as for all single lineages or different body size classes. However, in medium and large species the contrasts between localities were less pronounced, which was not the case for individual lineages of the assemblage. Contrasts of assemblage similarity between localities were much more evident than those for forest types and elevation zones. Significant correlation between species composition and geographic distance was found only for the assemblage of small‐bodied specimens. Seasonal change (dry–wet) in species composition was minor and only measurable in a few localities. The strong turnover between examined localities corroborates with the high degree of endemism in many phytophagous chafers, particularly in Sericini. Connected with their hypothetic poor habitat specificity and polyphagy, this might also explain why so many chafer crop pests in the Asian tropics are endemics.

“…Forest composition, forest management, forest re, environmental change, and spatial heterogeneity all affect the distribution of longhorn beetle diversity (Toledo et al 2002;Ohsawa 2004;Eliott et al 2019). Stand type, stand age, composition, sectional area, diameter at breast height (DBH), and dead wood affect the richness and abundance of longhorn beetles (Grove 2002 (Luo et al 2021). Stands with complex tree species composition and structure and a large variation in diameter class or age structure can provide more diversi ed food resources for longhorn beetles (Buongiorno 1994), and some species prefer to live in stands with large DBH (Casula et al 2021).…”

Background: Mongolian oak forest is a deciduous secondary forest with a large distribution area in the Changbai Mountain area. The majority of longhorn beetle species feed on forest resources, The number of some species is also large, which has a potential risk for forest health, and have even caused serious damage to forests. Clarifying the distribution pattern of longhorn beetles in Mongolian oak forests is of great scientific value for the monitoring and control of some pest populations. Methods: 2018 and 2020, flying interception traps were used to continuously collect longhorn samples from the canopy and bottom of the ridge, southern slope, and northern slope of the oak forest in Changbai Mountain, and the effects of topographic conditions on the spatial distribution pattern of longhorn beetles were analyzed. Results: A total of 4090 individuals, 56 species, and 6 subfamilies of longhorn beetles were collected in two years. The number of species and individuals of Cerambycinae and Lamiinae were the highest, and the number of Massicus raddei (Blessig), Moechotypa diphysis (Pascoe), Mesosa myopsmyops (Dalman), and Prionus insularis Motschulsky was relatively abundant. Topographic conditions did not affect the vertical distribution of richness and abundance of longhorn beetles in the forest, but topographic conditions and vertical height independently affected the composition and quantity of the beetle assemblages. The community composition of longhorn beetles in the forest bottom and canopy was significantly different, and the richness and abundance were higher in the canopy under good light conditions. Cerambycinae and Lamiinae preferred to be active in the canopy, Prioninae preferred to be active in the forest bottom, and Lepturinae did not show any difference in the bottom and the canopy. Conclusions: The composition of the longhorn beetle community on the ridge was significantly different from that on the southern slope and the northern slope, and the richness and abundance on the ridge and the southern slope were higher than those on the northern slope. Different species had different preferences for topographical conditions and vertical height, which indicated the adaptability of longhorn beetles in the forest.
