After 61 years without any sightings in India, the rare great four-ring butterfly was rediscovered in 2018. A team of researchers in Arunachal Pradesh spotted the butterfly near the Myanmar border, marking its first documented appearance since 1957. The butterfly, known scientifically as Ypthima cantliei, belongs to a genus with over 100 species and had not been seen in over six decades. 

Arunachal Pradesh has proven to be a haven for butterfly biodiversity, with 23 Ypthima species recorded in the region. The last known sighting of the great four-ring butterfly was in Margherita, Assam, in 1957. This recent rediscovery sheds light on the current status and distribution of this elusive species.
