“…We did not collect insects that did not belong to the order Coleoptera. We used a beetle specific collection method following Wardhaugh (2013) [43] by gently beating each flower or inflorescence Diversity 2021, 13, 604 4 of 17 3 times with a wooden stick while holding an insect net under said flower or inflorescence. Beetles that fell into the net were retrieved, and each specimen was stored in a small bottled containing 100% ethanol.…”

“…Evidence here suggests that flowers of plant species restricted to higher elevations may actually offer a broad range niches producing beetle diversity hotspots that may parallel the floral niches restricted to lowland tropical forests. Wardhaugh (2013Wardhaugh ( , 2015 [4,43] and Wardhaugh et al (2012Wardhaugh et al ( , 2015 [18,20] found that flowers offer an important microhabitat encouraging beetle diversity in Australian tropical forest. A primary difference in our study is that the majority of flowers preferred by our beetles belong to herbaceous species excluding shrubs in the Ericaceae and other plant families.…”

Background: Flowers are one of the important microhabitats promoting beetle diversity, but little is known about variation in the diversity of these insects at higher elevations. We do not know how divergent habitats influence the distribution of beetles among montane flora. Methods: We sampled beetles systematically in angiosperm flowers at 12 sites at two elevations (2700 m and 3200 m) and in two habitats (meadows and forests) for two consecutive years (2018 and 2019) on the Yulong Snow Mountain in Yunnan, southwestern China. Beetle diversity among sites were compared. Their interactions with flowers of identified plant species were analyzed using bipartite networks approach. Results: We collected 153 species of beetles from 90 plant species recording 3391 interactions. While plant species richness was lower at the higher, 3200 m elevation regardless of habitat type, beetle species richness was not significantly different among sites. Plant-beetle interaction networks were strongly modular and specialized. The structure of networks showed greater differences between elevations than between habitats. The turnover of networks was determined by species composition showing a weak influence by interaction rewiring. Conclusion: Our study showed a high diversity of beetles in flowers at higher elevations within this mountain complex. The role of beetles in plant–insect interactions within some sections of temperate, montane sites appear to be underestimated and warrant further study.

“…fogging) may influence the record of families, the taxonomic composition of the canopy-beetle community resembles that of other tropical rainforests. In concordance with the Venezuelan sample, the herbivorous families Curculionidae and Chrysomelidae were collected in high abundance [4,36,95,103]. Within the central Amazonian forests, herbivorous Curculionidae predominated in all forest types, whereas Chrysomelidae ranked second [104].…”

“…Aderidae, Anthribidae, Chrysomelidae, Corylophidae, Curculionidae and Staphylinidae were species-rich families of Fagaceae in New Guinea [107]. Along with Curculionidae and Chrysomelidae, Coccinellidae, Nitidulidae and Phalacridae were the most species-rich families in the Australian rainforest [95]. On Vochysia divergens Pohl in the Pantanal of Brazil, Curculionidae were the most species-rich family, followed by Chrysomelidae and Staphylinidae [108].…”

“…This study is comparable to a 1 year sample of canopy beetles collected from 23 canopy plants in an Australian rainforest. Wardhaugh [95] recorded 41 beetle families on flowers, and mature and new leaves. Although family systematics have been handled differently among studies, insecticide fogging methods often reveal more families associated with tropical rainforest trees.…”

Species richness, community structure and taxonomic composition are important characteristics of biodiversity. Beetle communities show distinct diversity patterns according to habitat attributes. Tropical rainforest canopies, which are well known for their richness in Coleoptera, represent such a conspicuous life zone. Here, I describe a canopy-inhabiting beetle community associated with 23 tree species in a Neotropical lowland rainforest. Adult beetles were sampled manually and in aerial traps using a large tower crane for a cumulative year. The sample revealed 6738 adult beetles, which were assigned to 862 (morpho-)species in 45 families. The most species-rich beetle families were Curculionidae ( n = 246), Chrysomelidae ( n = 121) and Cerambycidae ( n = 89). The most abundant families were Curculionidae ( n = 2746) and Chrysomelidae ( n = 1409). Dominant beetle families were found in most assemblages. The beetle community consisted of 400 singletons (46.4%). A similar proportion was evident for assemblages of single tree species. I found that 74.5% of all beetle species were restricted in their occurrence on host trees to the phenological season and time of the day. This daily and seasonal migration causes patterns similar to mass effects and therefore accounts for the high proportion of singletons.
