An insight into the butterfly (Lepidoptera) diversity of an urban landscape: Guwahati, Assam, India

Abstract

The paper deals with the butterfly diversity of Guwahati, Assam, India which was the result of a survey conducted from April 2016 to July 2020. During the study period we recorded 249 species of butterflies belonging to six families namely Papilionidae (24 species), Pieridae (23 species), Lycaenidae (57 species), Riodinidae (two species), Nymphalidae (97 species), and Hesperiidae (46 species). Twenty-eight species were recorded from commercial areas, 74 species from residential areas, and 248 species from forested areas. Nineteen species were found to be very common, 39 species common, 50 species fairly common, 53 species uncommon, 57 species rare, and 31 species very rare. Twenty-four species and nine subspecies including Discophora sondiaca, Athyma selenophora, and Athyma kanwa phorkys are legally protected under different schedules as per the Indian Wildlife Protection Act (1972).

Butterfly diversity and abundance in a sub-tropical wetland environment of Shyamlatal, Western Himalaya

“…Nectar resources that include several ornamental plants such as Cosmos bipinnatus, Anthemis punctata, Dahlia pinnata, Tagetes erecta, Duranta repens, fruit crops such as Citrus spp., Psidium guajava, Prunus persica, Pyrus pashia and wild native plants such as Viburnum cotinifolium, Anaphalis contorta, Erigeron spp., Pyracantha crenulata, Berberis spp., Elaeagnus umbellata, Trifolium repens, Micromeria biflora, Salvia leucantha attracted many butterflies in the lush green hill garden and adjacent mixed forest. These results are similar to those studies reporting more butterflies in forest habitats compared to areas disturbed or altered by human activities (Bhardwaj et al, 2012;Arya et al, 2020a;Bohra and Purkayastha, 2021), while few studies have also reported the converse of this pattern (Chettri, 2015;Mukherjee and Mondal, 2020;Koirala et al, 2020).…”

“…In second and third place, they were D. melanippus and P. sylvia, with individuals of 31 and 28, respectively. A presence of H. erylus in other places was previously reported by Bohra and Purkayastha (2021), who described that it was one of the species found among 249 species in the urban landscape of Guwahati, Assam, India. The authors described that it was considered a common species in the habitats of forested areas.…”

Computer 3D Scene Simulation of Ecological Landscape Layout Planning

“…e overall morphological structure of Fritillaria japonicum was described through data such as the length of branches at different levels, internode length of branches, and branch angle. Due to a large number of final branches (tertiary branches), they are usually built in batches by automatic generation in parametric modeling software, and then optimized and adjusted the crown shape of tree morphological structure according to field photos; e leaf density in the table ultimately determines the number of leaves in the three-dimensional tree model, and its numerical value is the ratio of the total number of leaves to the spatial volume of tree crown (the corresponding cylinder volume formed by crown width and crown height) [10,11].…”
