Group outings to Mahua Waterfall, Tambunan in Sabah (9-15 February 2020)

[chengailim]

After our outings to Chiangmai last year, we decided to go on another trip with sifu Khew to Mahua Waterfall in Sabah, who has been there before with Mei Yee.
This time, we have David Chan and his wife, Elaine and I who joined them.
Mei Yee had organised the whole trip and when we arrived there, we were all ready for the butterflies fun.

Although the butterflies activities were not fantastic, I was happy enough to encounter some of the endemic butterflies of Sabah and many new Malaysian ones that I have not seen in West Malaysia.
We just got back to Singapore yesterday and we will post some photos here to share with everyone. We would indeed appreciate the help of Dr Seow to assist us in indentifying some of the butterflies too.


My favourite endemic butterfly was the Big Eyed Jungle Lady or Silky Owl (Taenaris horsfieldii occulta). It was not a pristine fella, but it had us all very excited when Elaine who spotted it called out for us.
Indeed, we all had a jolly good time taking our shots.

Needless to say, The Kinabalu Swordtail (Graphium stratiotes) was my next favourite.

Very difficult to ID small lycaenid from the underside with the FW down.
There is no submarginal spot (lunule).
This narrow it down to 3 species.
See Borneo Lycaenidae . L88, L89, & L90.
http://www004.upp.so-net.ne.jp/jamides/Borneobook/borneo-e.html
L89. U. dilectissima can be ruled out because the two HW postdiscal spots 6 & 7 are equal.

This means it is either U. camenae or selma.
General appearance suggest U. selma but U. camenae is probably the commoner species.


2. Eurema ada.
FW with 2 cell spots; termen (margin) rounded.
HW postdiscal spot 7 a long sinuous streak.

The Tanaecia iapis complex is quite complicated in Borneo.
There are numerous forms which are either as ssp or forms.


Many authors now separated the type in Java as a different species.
eg T iapis iapis .
Male & female , Java.

The representatives from Sumatra, Malay & Borneo are referred to T. cocytina.
Further, some placed them under the genus Cynitia.

Although there are numerous named ssp. in Borneo the one in Sabah is generally ssp ambalika.

This form is named as taxon diardi but usually placed under ambalika.
See Tanaecia cocytina ambalika in funet.

As taxon (taxonomic name) diardi fig 2.

Yes it is Neptis leucoporos.

TL Seow: Cheers.

[chengailim]

Thanks Dr Seow.

Hi Federick,

Thanks! It was indeed a fruitful trip! Learnt from sifu the endemic butterflies of Sabah and they were just great.

I was so awed by the Borneo Birdwing ((Troides andromache) which flew all over the stream and was almost impossible to get any shots. So I just went on some crazy continuous shooting and was lucky to get one record shot with open wing. Here is the shot for sharing.

https://live.staticflickr.com/65535/49569862931_5b1f51f1ca_b_d.jpg


Also had great fun with the Borneon Mormon.

https://live.staticflickr.com/65535/49569922741_ab6d2b5578_b_d.jpg


It was fascinating to see them in quite a few numbers. I managed to take some fun shots.
