Yesterday ,I did a check on the "location" on the main island of Singapore where this species normally make its appearance around this time of the year, I did not find any.

Today , I was presently surprised to find hundreds of them on the flowering Acacia auriculiformis on the Keppel Bay area.

This species was a recent discovery in Singapore and reported in the Blog article here and also during a survey of Pulau Semakau

Looks like this tiny blue is gonna be here to stay with plenty of its hostplant all over the island.
