Silver Streak Blue (Iraota timoleon nicevillei)

Rather uncommon butterfly mostly due to its habit of flying in canopy and rarely descending to the lower levels. It is probably distributed throughout the country where its larval food plants grows (Varies Ficus species of family Moraceae) excluding higher hills. Almost all last century authors on butterfly fauna of Sri Lanka noted that Silver Streak Blue is common in Colombo (Ormiston W., 1924, Woodhouse L.G.O., 1950, and d' Abrera B., 1998). Larva feeds on fruits of බෝ/කපුටු බෝ (Ficus religiosa /Ficus arnottiana ), අට්ටික්කා (Ficus racemosa) and varies නුග species (Ficus benghalensis, Ficus drupacea, Ficus microcarpa, Ficus tsjahela) - (Jayasinghe H.D. et. al. 2014)
