Anyone been there b4? Any butts to "catch" there?

I've only been there once for a birding/recce trip. Consists mainly of mangrove swamps and forested areas. Not sure of insect wildlife there, but I did see some butts by the track on the way in, not sure which species as I did not attempt to ID them. (was in a vehicle then)

Maybe Khew/Gan or the veteran butt observers on the forums care to enlighten us on this place? Just looking for new alternative places besides the usual AH/BG/Sime track localities. One downside of Khatib Bongsu however, is that its really inaccessible if you don't drive.
