Iraota rochana masashimaruyamai

K. Saito 2013 - Scarce Silverstreak

A not uncommon species found in secondary vegetation. It is usually to be encountered when feeding on the fruits of the Singapore Rhododendron, which is a common wayside plant.

Until 2013, this species was considered to be the same as that found throughout Thailand and Malaysia. However, K. Saito showed that there were actually 3 subspecies present. The subspecies here is endemic to Samui and Koh Phan Ngan, not yet found on the Mainland.
