Hi... went to Butterfly Hill at Pulau Ubin recently and was really impressed with the number and variety of the butterflies found there... I chanced upon a shrub that's frequented by blue or dark glassy tigers which seemed to be sucking the sap of the fruits... I also noticed the shrub was host to many caterpillars which I thought initially belongs to the same butterflies. But upon checking with website pictures back home... I realized I may be wrong... either that or it's an early stage caterpillar. Please kindly help ID the butterfly caterpillar. Many thanks.
By the way, I saw a largish black snake (possibly a equatorial spitting cobra) slithered by in the undergrowth, it was mere few feet away... gave me the shivers...
