After so much of official activities it time for me and family to do some quality time ourselves. My in-law Suria have a piece of about 30km away from Miri, that is South West of Miri. He is a Kedayan and the very good tracker in the Jungle. After breaking fast we quickly go off to his land to chase away wild boar that been entering his farm.
We reached the farm around 8:30 pm and mount up our tent in his farm. While I and his son (Simi 10 years old) were installing the tent he went to the base of the hill to look for a wild boar.
We completed erecting tents and bring in sleeping bag. Suria came back telling us there was wild boar track still very fresh. But have not seen any. “The tapioca have been dug by the wild boar” he said. “Nanti dia” he commented a bit angry because the boar ate his tapioca.
He then bring me to a place he said should have firefly. So three of us went over the other side of the road . This area is not been cleared yet. There is a shallow stream in the jungle. We went in a bush grown up ex tractor road for timber extraction. Then we side wind into a bush in a marked track. In the track we saw many stick insect of different kind. There are also tarantula holes. The place is noisy with cricket and frog calls. We saw many fireflies at a distance in the bush. We cannot catch any due to not bringing the scoop net.

Then I instructed all of us to switch off out head light and stay quite. This action is very dangerous, because this area is always having people hunting in the jungle. For safety precaution we are wearing a reflective jacket. Not long in the dark we saw many firefly larvae. They are blue twinkle on the grown. Most of them are deep in the under growth. We saw one just at hand reach and manage to catch it. This one is totally new to me having soft body. First look it might be a glow worm. But having the Thorax area the 3 pair of leg and the typical head wit small clay suggest it a firefly larvae. There is no container except for the mineral water bottle. Put it safely in a water bottle for photographing and identifying of what species it is. Take the GPS waypoint and time of the larvae capture.
Shime being small is can get into the bush , and caught a mature firefly. It was around 15 mm in size. It was a male firefly. However before we can put it in the bottle, it flew away. We tracked about a kilometer into the track and return to our camp.

The sky was very dark and the heaven above us were full of stars. I have regretted for not bring any camera to capture star trail. Seen some mentor streak through out the night around Perseid constellation at the northern sky at morning hour.
It was so tiring after the fasting and I slept like a rock. Woke up at 4am to have our morning meal for the fasting the next day. We stayed awake to watch the sun rise over the Eastern sky.
Yui Vor's Specimen from Honh Kong.
In the morning Suria and Shimi goes down hill to see if any more visit by the wild boar. The sun is rising fast and it already getting hot. We rush to pack up our tent and go home.
At home I took photographs of the larvae and send to Hong Kong to Yui Vor and to the rest of our Team in the US (Lynn Faust) and Australia (Dr. Leslie Ballantyne) and in KL (Sonny Wong) and Sabah (Dr. Mahadi Dawood) for Identification. Yui Vor is very experience of Identifying firefly larvae and he reared them to be release. Just within minutes Yui Vor send me the Id of the larvae. The species is of a mature larva of Stenocladius sp.

Sungai Raan Firefly Watching After AGM 2011/2012
The Malayis Nature Society Miri branch Annual General Meeting session 2011/2012 was held at Beraya Laut Resort, about 30 kilometers south west of Miri. We decided to have a firefly of Raan River, and at the same time collecting data for the firefly display trees. Sungai Raan is 2 kilometers Sout East of Miri. Sungai Raan Share same Estuary with Bakam river.
We are to meet at bakam Jetty just at the side of the road where the food stall and The Bakam bridge is. We have rented 3 boats for this occassion. The three boat drivers have waited for us. The boats belong to Pak Jugi who is the fisherman.
Nazeri is helping to push the boat with a long stick.
Before going into the boats, Nazeri gave the participants Boat Safety briefing. The most important is not to sit at the boat side and not to put your hand on the boat side. There are crocodidile in the river and they dont post any danger, if we stay in the boat.
As I have been told by pak Jugi the tide that night is very low. ”It would be difficult for us to pass through at the second bridge” he said. The moon is at it late last quater.
The boatman is pointing where a crocodile is.
When all the boats are loaded wit people, went out to the Bakam River mouth. This is where the Raan river river mouth is. We went into river Raan and the first Display tree was still the same one previously mapped to the left of our track before the bridge. The bridge is for the local to cross the river, where the Muslim cemetry located. The Cristain cemmetry is alocated not far from the muslim cemetery. All along the river we saw Firefly display Trees.
Boat landing Huts.
When we passed the area where the boat landing and jetty for the local, there are no nmore display trees seen. We went through many patches of shallow water where it was difficult for the boat to monevour.

We did pass throuh the hawai beach bridge. But as we went out about 100meters further we got stuck at the sand bottom of the river. Our boat man jump into the river trying to get the boat pass the shallow area, but failed. He suggested we should wait for the water to rise. The tide should be coming in at 10pm. We decided we just turn back.
It was difficult for the boat man to turn the boat . Finally we manange to turn the boat and going back is a little easier because the water is also still going down.
As we make our move slowly along the river one of the local residence asking out boat driver “Tengok Buaya kah?”. “Looking at crocodile” the man at the side of rier asked. Our boat driver answer “Mana ada buaya lagi, lu orang dah tembak”. It is well known amoung the local there that the wild crocodile in the river are either nettet or shot to be send to Miri Restaurant.
Nazeri is to move to the bridge to control the situation
It was dark at some area where the firefly display trees are. But this will soon be gone. The light fron the street light and car head lamp do passed through the thin three curtain along the river. We finished our trip at 10 pm.

The last time we visited Kpg Kuala Suai was June 2009, Musa and Daniel were here sometime in January 2011 during the SWS (Sarawak Waterbirds Survey). The journey downriver to the kampong is's just like a trip going home.
We met our boatman Azman and his younger cousin Nazeri by the Suai Bridge apprixmately 1700hrs, we waited till sunset before commencing our survey.
We immediately started the survey at 1850 hrs, a few minutes after sundown. The journey downriver was approximately 1.5 hrs navigating a winding river in the dark. We spotted a total of 29 display trees with occasional rovers flitting about on the tree tops. There were also several crocodiles spotted playing hide-n-seek under the nipah palm as we made our way further downstream. We came across several boats engaged in fishing activities, mostly aiming for prawns.
A good number of samples were also collected that night that should give us an identification of fireflies common in the area.
On the way back the next morning, we took the opportunity to capture images of the display trees we encountered the evening before.

A typical "bakau" tree that harbored most number of fireflies from image "5397". A major part of the river is covered by Nipah palm. Most of the surrounding area along the river has been earmarked for oil palm plantation except for small packets of forest here and there.


Other than a small isolated patches of forest, the surrounding of Sg Suai is almost entirely dominated by oil palm plantation, some right up to the riverbank.
