Jewel Four-ring (Ypthima singala)

Rather rare butterfly flies all the year round mainly in the Uva patanas from 500 -1500m elevations. Sightings also available from Galaha, Elpitiya, Haldummulla and Watawala. Larval host plant is not known though egg laying was observed in a unidentified grass species and larva has been successfully reared on Carpet grass/පොටු තණකොළ (Axonopus compressus) (van der Poorten, G. and van der Poorten, N. 2012)
