Let's start my report of Koh Phi Phi butterflies. I have met more than 70 species of rhopalocera in one week and pictured about 50 of them.
Let's start with Nymphalidae.
Tanaecia julii bougainvillei is a splendid Nymphalidae which lives only in the forest. Males are territorial and are easy to spot thanks to their splendid fluo-blue band on the recto. In the darkness of a tropical forest, this touch of vivid blue is a wonderful sighting. It is about 70 mm large.
Males often rest on trees along the paths of the forest.
In my "Butterflies of Thailand, 1st edition" by Ek-Amnuai : - female bougainvillei have white spots in FW like mine, whereas spots of xiphiones females are brown - bougainvillei is done from type locality Songkhla and xiphiones from Kanchanaburi, Phiphi is closer from Songkhla
It seems Ek-Amnuay changed his mind in the 2nd edition of his book, there he has mansori Yokochi, 1993 = bougainvillei (Corbet, 1941) from Satun and xiphiones (Butler, 1869) from Kanchanaburi, Ranong, Phuket.
According to the Kimura volume, mansori was described from Langkawi and may be present on Tarutao Island, which is a very interesting place in Thailand just north of Langkawi.
