Butterfly Species #18 in my garden

Today, my Mrs alerted me to a 'large black butterfly' hovering over above me. I looked up and there is a King Crow (Euploea phaenareta castelnaui) circling over my garden !

The crow must have came from West Coast Park where there are many Pong Pong trees (Cerbera odollam), its larva host plant. It must have been attracted by my Dill plant. On 14 Dec, I spotted a Dark Glassy Tiger (Parantica agleoides agleoides) circling my dill plant and it stayed for 2 days before disappearing.
