Graphium sarpedon sarpedon

Linnaeus 1758 - The Common Bluebottle

Koh Samui and Koh Pha Ngan.

A common, and very well known species, which can easily be recognised by the blue/green band running down the centre of both wings, on upper and underside.

This is a very rapid flyer, but can be seen patrolling paths and streams on the edge of forests, and also drinking up salts from damp ground (puddling), often in large numbers. These puddling butterflies will all be males. Females very rarely puddle, and in this species, are considerably rarer than the male.
