“…Studies on butterflies in the Eastern Himalayas are focused mostly on their diversity in protected areas or the forest ecosystem (Chettri, 2015; Chettri et al., 2018; Dewan et al., 2019; Kumar Acharya & Vijayan, 2011; Sharma et al., 2020), whereas few ecological studies of butterflies are conducted in relation to their nectar or larval host plants (Ghosh & Saha, 2016; Sengupta & Ghorai, 2013). Many studies of butterflies in the Western and Southern Himalayas have recorded a high diversity of butterflies (Arya & Dayakrishna, 2014; Kumar et al., 2017; Singh & Sondhi, 2016; Tyagi et al., 2011; Uniyal & Mathur, 1998) and a few more studies have examined butterfly‐plant interactions (Arya et al., 2020; Nimbalkar et al., 2011; Tiple et al., 2005, 2009).…”

Floral attributes often influence the foraging choices of nectar‐feeding butterflies, given the close association between plants and these butterfly pollinators. The diversity of butterflies is known to a large extent in Nepal, but little information is available on the feeding habits of butterflies. This study was conducted along the periphery of Rupa Wetland from January to December 2019 to assess butterfly species diversity and to identify the factors influencing their foraging choices. In total, we recorded 1535 individuals of 138 species representing all six families. For our examination of butterfly–nectar plant interactions, we recorded a total of 298 individuals belonging to 31 species of butterfly visiting a total of 28 nectar plant species. Overall, total butterfly visitation was found to be significantly influenced by plant category (herbaceous preferred over woody), floral color (yellow white and purple preferred over pink), and corolla type (tubular preferred over nontubular). Moreover, there was a significant positive correlation between the proboscis length of butterflies and the corolla tube length of flowers. Examining each butterfly family separately revealed that, for four of the families (Lycaenidae, Nymphalidae, Papilionidae, and Pieridae), none of the tested factors (flower color, plant category, and corolla type) were shown to significantly influence butterfly abundance at flowers. However, Hesperidae abundance was found to be significantly influenced by both flower color (with more butterflies observed at yellow flowers than purple) and flower type (with more butterflies observed at tubular flowers than nontubular flowers). Our results reveal that Rupa Lake is a suitable habitat for butterflies, providing valuable floral resources. Hence, further detailed studies encompassing all seasons, a greater variety of plants, and other influential factors in different ecological regions are fundamental for creating favorable environments to sustain important butterfly pollinators and help create balanced wetland ecosystems.

“…Mainstream methods such as Pollard's walk and transect count (Pollard 1977, Isaac et al 2011 were not feasible because of the steep topography. Our method has been used in a considerable number of previous studies (Chettri et al 2018, Dewan et al 2019a, Sharma et al 2020 and is recognized as an appropriate technique to sample butterflies (Kral et al 2018). Butterflies were sampled along an elevation range from 300 m to 3300 m a.s.l.…”

Understanding the pattern of biodiversity along environmental gradients helps in identifying diversity hotspot areas that can be prioritized for conservation. While the elevational distribution of several taxa has been studied, responses of the subgroups within a taxon to elevation and its associated factors are not properly understood. Here we study species richness and butterfly density along an elevation gradient in Sikkim, Eastern Himalaya, India and explore the underlying causes of the patterns. We sampled butterflies using a fixed-width point count method in 16 elevational bands (150-200 m intervals), between a range of 300 and 3300 m a.s.l. We categorized butterflies into various subgroups based on family, range size, biogeographic affinity, and host-plant specialization. We recorded 3603 individuals and 253 species of butterflies after the completion of 1860 point counts. Overall, species richness in the majority of the subgroups (except for Riodinidae and Palearctic species) declines with elevation, as does the density of almost all the subgroups. From a selection of environmental factors, annual actual evapotranspiration has the strongest effect on the species richness pattern of butterflies as well as on the density of the overall butterfly community, especially the Lycaenidae family. The richness and density of butterfly groups display varied responses to the richness and density of trees and shrubs. The conducive climatic conditions and diverse habitats in the lower valleys of the Eastern Himalaya support a high diversity of butterflies (with majority of small range species) and thus warrants conservation attention. Highlights • The distribution of biodiversity along mountain elevational gradients has been well studied, but the disparity in patterns between various organisms and associated factors makes it difficult to develop a universal model for explaining the variation of biodiversity. • We report elevational patterns of species richness and density of butterflies in the Eastern Himalaya, both at whole group and subgroup levels. • A general decline in species richness and density with elevation is not supported for Riodinidae and for Palearctic species. • A measure of water energy balance, annual actual evapotranspiration, is the best correlated variable with species richness trends in butterflies. • Our paper highlights the importance of low elevation forests for butterfly diversity in the Eastern Himalaya.

“…Kupu-kupu merupakan salah satu jenis serangga dari ordo Lepidoptera yang memiliki kombinasi corak warna yang variatif sehingga banyak diminati oleh masyarakat terutama anak usia dini. Kupu-kupu merupakan bagian dari kehidupan di alam, yaitu sebagai salah satu satwa penyerbuk pada proses pembuahan bunga (Sharma et al, 2019). Hal ini secara ekologis turut memberi andil dalam mempertahankan keseimbangan ekosistem dan memperkaya keanekaragaman hayati.…”

Penelitian ini bertujuan mengembangkan media grafis untuk pengenalan life scence Kupu-kupu pada anak usia 5-6 tahun dengan metode penelitian Research & Development/ R&D. Studi ini menggunakan metode model ADDIE (Analyze, Design, Development, Implementation, and Evaluation). Data dikumpulkan melalui analisis kebutuhan (studi literatur, analisis komparatif, wawancara & observasi), angket untuk pakar. Hasil penelitian uji draft media grafis menunjukkan bahwa dalam pembelajaran life science kehidupan Kupu-kupu dinilai cukup berhasil setelah menggunakan media grafis dibanding dengan metode konvensional hal ini di lihat dari catatan pelaksannan melalui tiga tahapan, yaitu perencanaan pembelajaran, pelaksaan pembelajaran dan evaluasi. Kesimpulan yang diperoleh adalah bahwa media grafis layak digunakan untuk meningkatkan pengenalan kehidupan Kupu-kupu pada anak usia 5-6 tahun di Kabupaten Musi Banyuasin provinsi Selatan.
