I have selected the provisional identification of this one as Papilio ulysses, given that its Winspan between 106-108 (registered for this species) and it being a fairly distinctive species. With a brilliant iridescent blue in the upperside of the wings, and with an erratic flight, this was found not far from a large patch of Lantana camara (which they are known to feed on) patch but within a well shaded forest remnant in a deep valley of Meokana spring.

It is a sight to see it flying as if flies through some of the sun rays that make it pass the canopy. The underside patterns while less noticeable during flight, are somewhat interesting. This was found not in what I would consider a rain forest, but a deep valley with very good canopy cover (between 50-60%). While I went in this particular visit to photograph Damselflies and to do a recognizance visit for a more adventurous collection of crepuscular species collection (odonatans) and some mild moth collection, I did not take my kill jar, so this specimen was badly damaged by the time I arrived home after a somewhat long tenuous walk and a stop over by the pub.

For this particular ID I used Braby et al. (2018), but was not convinced, so I resorted to Braby (2016), which tends to be my main guide nowadays. Again I do not necessarily know my butterflies well enough to ID them to species level, but this was so strikingly different that I couldn’t resist to try.

This site was particularly good for butterflies, I may do a collection if there is anyone out there happy to help me out with the Identification.
