030. 4 ‘Kids’ & 1 Huge ‘Playground’ – Semakau Land Survey Pt.1

IMG_2052-2It was a trip down our childhood years as 8 of us literally bashed through the wild grassland that grew with abundance in the landfill cells. Never mind that the Mimosa stood tall and overshadowed the smallest of us (approx. 150cm in height), all thoughts of prickly burrs from the Love-in-the-Mist (Passiflora foetida) and thorny abrasions flew as Jia Yi and I exclaimed excitedly over our finds. Spiders, grasshoppers, butterflies, dragonflies etc were all part of our treasure trove as we swept figure-of-eights over the heads of the swaying lalangs. With Robert as boss of our team (and Ed as leader of the other), us 3 girls slowly became acquainted with the microfauna that made up the inhabitants of Semakau’s unexplored grassland.

(right): .. before we entered the tall, thick overgrowth. The cells that we entered are the ones that have already been packed to the brim with ash (rubbish-incinerated produce). None of the plants found here are human-introduced but were instead dispersed by the wind and creatures like birds. Notice the irony of the situation? :) (of course, we are there for a purpose, hence it’s a-ok!) But before moving on, let’s introduce the intrepid ‘pioneers’ of the insect-team!

(left): The youngest and the most bubbly of this surveying team is Jiayi. Though many a times she got overshadowed by the tall, prickly Mimosas, she made her way through slowly. And her ‘haul’ of the day included a rather thug-like hornet, several dragonflies and tons of spiders (none were hurt in the process). =)

(middle): With a concentrated look, Meiyi made sure she didn’t miss out any potential microfauna that will be useful in mapping out the inhabitants of the grassland-cum-ash-filled cells ecosystem of Semakau. 

(right): Halfway through the sweeping-checking-transferring-releasing process, Ying Wei got side-tracked and ended up in our group. :) Transferring the many-legged creatures into containers require full attention as we wouldn’t want them escaping. Also, we had to be careful that neither us nor the animals get hurt in the process (we might get stung while the latter might lose a limb).

And last but not least, we had Robert as our Columbus to pave a way through ‘unchartered’ territory. It ain’t easy being the first man at the front since the grasses proved to be quite the formidable wall. Roots and the snaking rhizomes could easily cause a trip if not careful. Also, the thick and dry turf that we stepped on were so uneven that a slight imbalance could cause one to fall down and kneel over. With an impish grin, Robert said that he didn’t mind the ‘royal’ treatment … –.–”’

1st: Testing out skills before meeting the grassland head-on. Once entering the bushy overgrowth…

2nd: … it’s time to sweep, sweep and sweep!! Leave no stone unturned as they say. :)

3rd: Once a small patch is explored, stop awhile to check on the insects captured. Seek advice to avoid containing the same creatures. All that was needed was 2-3 of each species.

4th: Transfer creatures into appropriate containers. Butterflies and dragonflies went into the larger ones while tiny spiders can be sufficiently enclosed in one of those slender tubes (right pic).

IMG_2043-1Time for a short water break before carrying on. Since we only had 3 nets per team, I was in-charge of carrying the containers that temporarily housed the specimens. Also, if in need of an empty container?  Just give me a holler~ =)

We were given 2 hours to net as many creatures as possible. By the time we near the end, I had a bagful of containers that were a-buzzing with life. Quite a haul too and we didn’t even had to walk all the way through one end of the cell to the other end. We knew we had reached the road when the refineries came into sight (right pic).

Against the setting sun as backdrop, Robert can be seen sweeping for the last time before we packed up our equipment and called it a day.

(left): As we were busy sweeping for insects and spiders, the bird team set up mist nets nearby to catch birds for identification. The ones that faced sideways can be easily seen while the ones that faced frontwards blended easily against the background.

IMG_2088-1And the haul from the 2 combined teams, with 2 bottles of alcohol standing-by for preservation purposes. Later, the organisms were sorted out via generalised categories like ‘Spider’, ‘Dragonfly’, ‘Bee’ etc.

IMG_2105Taking images of the arachnids were not an easy job as still focus and lively spiders don’t usually go hand-in-hand. 

IMG_2163One of the captures of the day – a robber fly (aka ‘Robert’ fly) from the family Asilidae. The dense moustache on its face helps protect its head and face from preys that just don’t give up easily. Its short but strong proboscis is used to stab and inject its victims with saliva that paralyzes and digest the innards, before it all gets sucked up. The adults attack other creatures that range from other flies to to the predatory spiders. It’s cool but damn, this sure is one vicious fly. *nods*
