When new to looking for them, it's usually very difficult, so you will depends on the guides/spotter to show them to you. After you have seen them for a couple of times, you will know where and how to look for them :D, which is not too difficult as they tends to stay in the same host seaman for a long time, unless disturbed/harassed.

Thanks again, @Gaia80 but I get most of the info by Googling and Wikipedia :D

Thanks, @Gaia80.
The species Synanthedon tipuliformis is endemic to the Palearctic ecozone, but is an invasive species in the Nearctic ecozone and the Australasia ecozone. So, probably not the species or like you said, a sub-species. Unless its also an invasive species to Borneo.

Thanks, @Michael Sarill and @Lauren :)
