Rare butterfly species Common Lineblue, (which was last seen in 1962 in Delhi) and Dark Cerulean (which was last spotted in the late 90s) were spotted by researchers in 2018 after a gap of over half a century.
- Both Common Lineblue and Dark Cerulean butterflies are usually found in the Himalayan foothills.
- Researchers and lepidopterologists (branch of entomology concerning the scientific study of moths and the three superfamilies of butterflies) have noted that resurfacing of the two rare species of butterflies in the Delhi points towards the expanding floral diversity of the region that attracts new butterfly species from adjoining places.
