@Mark - I have seen several others similar to this, and the wings are of the same 'look'.

Not sure which you are referring to, but the white 'circular' line is the the border/edges of the operculum cap, which the nymph will hatch from. Not exactly sure how it is done, but the operculum cap is like a door, which it 'pushes' up a bit and hatched from there.

Nice pics to see, but it does looks like a stressed snake?

Thanks @Richard Ong for the ID :)

@Brian38 - this is not the first spotting of this species at PN.

At Wikipedia, the scientific name is Galeopterus variegatus.
There are four known sub-species from different locations :
- Galeopterus variegatus borneanus from the island of Borneo
- Galeopterus variegatus variegatus from the island of Java
- Galeopterus variegatus temminckii from the island of Sumatra
- Galeopterus variegatus peninsulae from Peninsular Malaysia and mainland South East Asia

However, since the publication of work by Janečka et al (2008), Galeopterus variegatus borneanus has widely been considered as a separate species, or even a species complex.

At PN, there are more than 10 spottings of Galeopterus variegatus, however, if based on locality, there are 6 spottings of Galeopterus borneanus but identified as Galeopterus variegatus.
