Two images of Common Bluebottle Graphium sarpedon luctatius taken from Chiang Dao, northern Thailand.
One of these two has an additional spot in the forewing, and generally looks more colourful and the band across the wing appears wider. I can find no other images on the web showing an additional spot in the wing. An aberrant? Any comments gratefully received.
Thanks
