Lamproptera curius curius
Fabricius 1787 - The White Dragontail
Koh Samui only.
One of two very similar butterflies, the sole members of the Genus, the other of which, Lamproptera meges (The Green Dragontail), has not yet been found on Samui, but can be seen close by on the mainland, and should be looked for here. It is generally considered that this is much the rarer of the two. They are small butterflies for this family, and can usually be found near running water, often puddling on the sandy shores of riverbanks. Unlike most 'puddlers' the Dragontail prefers to puddle away from other butterflies.
In flight, this species looks nothing like a butterfly, and can be mistaken for a dragonfly, or some other insect.
This species can be distiguished from the other by the white bands on the fore and hindwings, and in the male, there are adroconial scales in the anal pouch of the male hindwing upperside, which are absent with Lamproptera meges.
25 - 37mm
