“…Three individuals were again sighted on the same day in an adjacent stream. The species, though widely distributed across the Himalaya with its known western distribution up to Himachal Pradesh (Kirti et al 2016;Anonymous 2018a), was recorded for the first time from the state of Jammu & Kashmir.…”

“…The present locality is around 500 km (aerial distance) away from previously reported nearby locality at BTR of Alipurduar district in north-eastern part of West Bengal. Moreover, the species is distributed from Uttarakhand to Northeast India and West Bengal, Odisha, Jharkhand, Himachal Pradesh, Andhra Pradesh and Chhattisgarh in India (van Gasse 2013;Varshney and Smetacek 2015;Kehimkar 2016;Kirti et al 2016;Payra et al 2016;Sisodia and Naidu 2019;Gokhale 2021). Globally, Vagrans egista is distributed in Nepal, India, Bangladesh, south China to South-east Asia, i.e., Myanmar, Thailand, Laos, Cambodia, Vietnam, Philippines and parts of Indonesia and Malaysia (Kehimkar 2016;Inayoshi 2021).…”

Vagrans egista (Cramer, 1780) is reported for the first time from southern part of West Bengal, India. The Raygar forest of Bankura district in the plateau region is the second locality for the reported species in West Bengal, which extends the distribution range (aerial distance: 525 km) of the species from its known locality, Buxa Tiger Reserve of Alipurduar district in the state. This paper also reports occurrence of Rapala pheretima and Gerosis bhagava in Bankura district for the first time. Importance of an invasive plant, Mikania micrantha has also been discussed as a nectaring plant of butterflies.

Vagrans egista sinha (Kollar, [1844]), the Himalayan Vagrant is a subspecies of Nymphalid (Brush-footed) butterflies spread across Asia, whose western limit is in the north-west India. Observations of this subspecies have considerably increased over the past half-a-decade, with a spike in new sightings to the west of their previously known range. This has been considered as a range extension. The current study reports new records of this species from Bilaspur District, Himachal Pradesh, India (which are the first records for the district), through systematic and opportunistic sampling. This raises the question of whether the purported range extension towards the west could instead be a range shift or vagrancy, and whether there is any shift in elevational ranges in the populations across their known range. Questions pertaining to spatial differences in elevational ranges and seasonal variation, across their range, also piqued our curiosity. Using data from academic sources (such as published literature and museum collections), supplemented by data from public participation in scientific research and personal observations, these research questions are addressed. The accuracy of results when using citizen science data is also explored using the same dataset, focused on the impact of method of extraction of coordinates, and elevation derived from it under different scenarios. It was discovered that there has not been a range shift (either longitudinal or latitudinal) and observations do not suggest vagrancy but a case of range extension. Other results indicated that there was no climb of population to higher elevations, no spatial differences in elevational ranges in the populations, or seasonal variation in activities across their range. It was also discovered that the method of data collection by, and extraction from, citizen science databases, can influence the accuracy of the results. Some problems involved in collecting data are discussed, and remedial solutions are suggested.

Vagrans egista sinha (Kollar, 1844) (Lepidoptera: Papilionoidea: Nymphalidae): range extension and an addition to the butterfly fauna of Himachal Pradesh, India

Abstract: This paper reports the first record of Vagrans egista sinha (Kollar, 1844) (Lepidoptera: Papilionoidea: Nymphalidae) from Himachal Pradesh, India, extending its known distribution (Dehradun to Sikkim, Bengal, Orissa, Assam and Burma) by 250 km westward, beyond the Sutlej defile.
