Diversity of moths (Insecta: Lepidoptera) in the Gupteswar proposed reserve forest area of Eastern Ghat hill, Koraput district, Odisha, India was studied for the first time. Total 30 species of moths under 27 genera and 7 families were observed. Highest numbers of species and genera were observed under family Crambidae, followed by family Geometridae and family Erebidae.

ABSTRACT Aim Location Study Period Major Taxa Studied Methods Results Conclusions This study examines how environmental variables determine the co‐occurrence of Phylloscopus warblers. It was carried out using an integrated zeta (ζ) diversity estimation method and multisite generalised dissimilarity modelling (MS‐GDM).Phylloscopus species spanning Eurasia.Observations made during the breeding season for each species from 2014 to 2023.We specifically focussed on complexes/superspecies groups within the genus Phylloscopus to address this question. The groups defined on recent phylogeny are the P. castaniceps complex, P. cantator group, P. borealis group, P. burkii complex, P. affinis group, P. proregulus group, P. inornatus complex, P. davisoni group, P. fuscatus group, P. collybita group, P. trochiloides complex and P. tenellipes group.We used ζ diversity estimations to quantify the extent of compositional turnover and diversity across multiple sites. We further used MS‐GDM to gain insights into how various environmental variables impact species composition.The composition of the groups we analysed is shaped by environmental conditions. The normalised difference snow index considerably impacts turnover within the P. castaniceps complex, with species such as P. castaniceps showing adjacency to snowy areas. Elevation and gravity anomalies play an essential role in the turnover of species in the P. cantator and P. borealis groups. The prevalence of positive gravity anomalies (variations in gravitational strength) in hilly areas determines the compositional differences within the P. burkii complex. The turnover of the P. proregulus group is influenced by both artificial night lights and gravitational anomalies. The turnover in the P. trochiloides complex and the P. davisoni, P. collybita and P. tenellipes groups is influenced by soil moisture, elevation, gravity anomalies and aridity index, emphasising the varied ecological niches of these species.This study improves our understanding of the compositional shift of Phylloscopus leaf warblers over space and reveals the mechanisms underlying shifts in their composition across regions and the impact of changes in climatic patterns. As a result, this study is an important resource for ecologists and conservationists. [ABSTRACT FROM AUTHOR]
