Another Blue Dragonfly With Dark Wing Tips

This is another blue dragonfly with dark wing tips, a rather similar description as for the Cratilla metallica, but this dragonfly is much smaller in size and it is also of a lighter blue.

It is the Diplacodes nebulosa of the family Libellulidae and the male has hindwing length of only 19 mm.  According to the Pocket Guide, this species is widespread in tropical Asia.

I had come across this dragonfly for the first time in February-March 2010, over a year ago now, and have not seen it again since.  Perhaps because I have not been looking out for it in particular.

It would be nice to spot it again one of these days...
