It has been esmated that over 40% of the insects are declining at a rate eight mes faster than mammals, birds and reples (Sánchez-Bayo & Wyckhuys, 2019). The major drivers threatening the decline in insects are habitat loss, polluon, pathogens/invasive species and global climate change. The Lepidoptera along with few other invertebrates (bees and dung-beetles) is regarded to be the most affected taxa in the terrestrial ecosystem (Sánchez-Bayo & Wyckhuys, 2019). Studies have shown that the species richness and abundance of buerflies are declining at an alarming rate in Europe (van Swaay et al., 2006), the United States (Breed et al., 2012; Forister et al., 2016) and in countries of Asia such as Japan 34 PANDA | Vol. 13 | ISSUE 4 | 2021 (Nakamura, 2011) and Singapore (Theng et al., 2020). Several Many studies have recorded high diversity of buerflies in buerflies have also shied their range uphill and towards such agroecosystems, e.g. Vietnam (Van Lien & Yuan, 2003), higher latude since lowland and the tropics have become Costa Rica (Horner- Devine et al.,2003), Japan (Kitahara, increasingly warmer for buerflies to thrive (Wilson et al., 2004) and USA (Meehan et al., 2012). All these studies have 2007).

The effort to conserve biodiversity has generally been India is of the mega diverse naons and host around 1500 focused on establishment of protected areas (PAs). The PAs species of buerflies.

The PAs and forest reserves are reports that over 50,000 specimen of buerfly are smuggled known to be efficient in conserving buerflies since their out of India every month. Consequently, some species have habitat remains protected (Rada et al., 2018) but many become extremely rare and endangered. One of the species of buerflies also occur outside PAs, especially in important measures taken by Government of India to protect human modified landscapes (Sharma et al., 2020). Majority these buerflies is by including them in Schedule List of of the species that occur in human modified landscape does Wildlife Protecon Act (1972). A total of 128 not occur in PAs. However, establishment or expansion of PAs species/subspecies of buerflies are protected under is not feasible in the human dominated landscape. Therefore, Schedule I (Part IV) and 307 species/subspecies are protected it becomes necessary to direct conservaon measures under Schedule II (Part II) of WPA (1972). A total 123 towards non forested areas, especially agricultural buerflies have been assigned to naonal Red List Category ecosystems. following the standard norms established by the Internaonal Union for Conservaon of Nature and Natural The agricultural landscape constutes about 36.90% of the Resources (IUCN) (Gupta & Modal, 2005).
