Island Cyclosa Spider


Island Cyclosa Spider and its death

Today was the most amazing day. We heard so much about wasp predating spider however we had not seen it before. We saw a massive attacked mounted by two wasps on a series of orb web spiders, the Cyclosa Insulana. I found the name in the small little guide, written by Joseph K. H. Koh

I first spotted the web of this particular spider and noticed an ugly lump in the middle of the orb web. I guessed it must be a spider, which retracted all its legs tightly against its Cephalothorax and Abdomen. I was right after observing it through my 100mm macro lens. This spider had short and thin legs. It was perching behind the web instead of above it. The web probably served as a shield and protection from spider attacker. As it was hanging, the short and thin legs close to the major mass of the abdomen would cause less strain on his legs, as the strain was in tension rather than compression. This accounts for thinner and shorter legs, which would reduce buckling. This was vastly different from the St. Andrew’s Cross Spiders that has long, sturdy and thick sectioned legs; the legs also works in pairs when he perched right in the middle of his orb web. Through comparison, we understand why their legs were built differently for different purpose and in relation to their mass.


Just as I was taking a break and lifted my eyes off the orb web. I spotted a wasp flew near the spider and attacked him. It dropped straight down and swing underneath the leaves. It was fast. Next the wasp flew off to look for other spider.


In the next moment, we saw another spider dropped from above my head. I followed the single silky thread and found him daggling precariously on it. I lifted the thread and tried to place him on a leaf but it was not able to cling on to it. He fell again and hung on the silk thread. I thought, I could photograph him and study his injury later in the computer. I started photographing him. I noticed he could only move his two front legs but not the rest and he had fewer legs. The attacked by the wasp was deadly. The venom was kicking in and he was motionless in less than 2 minute.


We knew he was bitten but we were not able to see his injury until we reviewed it in the computer. The upper portion of his body was torn apart revealing a huge gust of fresh wound. The wound was fatal.

We suspected that the wasp would come back for him. We were right. The wasp came and started eating and tearing the abdomen of the spider.

We watched the wasp hanging and nibbling away the dead spider. Above this happening, another wasp was nibbling another Cyclosa in the middle of the orb web, the detail of which was obscured by the limitation of our vision. We only saw movement and more movement lasting about 5 minutes before the wasp flew off. There were so much happening at the same time, we had so much to watch in the same instance. I chose to photograph the wasp nibbling the dead Cyclosa. The sun light was not that bright and I had to shoot with a huge aperture which resulted in shallower depth of field, however, I like the cinematographic effects, especially when they are convert into pastelmatic colours.


We watched the wasp nibbled in mid flight and reduced the abdomen of the Cyclosa to a sheet of mangled skin. The sight was somehow not gross because we could hardly see any bleeding or hear the Cyclosa screaming. It was as if we were watching a silent movie, except it was a rare chance to watch and photograph the wasp in mid flight exposing its aerodynamics and displaying its anatomy. We were awed and our adrenaline drove us wild.

Nature is oblivious to cruelty and survival is acting out before us. The wasp could be the Spider-eating Wasp of the family Pompilidae of the order Hymenoptera. A lot was written about wasp that laid eggs on the spider but few had written on the wasp feeding on the spider.

At another orb web, we saw a spider scurried into the middle of the web and carried the injured Cyclosa and hid within two folding leaves. He crawled very fast. We suspect that it could be another Cyclosa or possibly they shared a single web. Since one was dead, the other might as well have a good feast. However, we were wrong, through enlargement in our computer, the colour and posture of the predatory spider was not a Cyclosa. It was a spider, but with longer legs and orangey colour. We could also see from the photograph, the Cyclosa was roll wrapped in spider silk. Nature always weeds out the weak and the injured. It was reality. When any animal is injured and weakened, he has to be extra vigilant and find a safe heaven to recuperate, otherwise death will arrive sooner.


We watched a life perished within that short sudden instance; life is so insignificant and trivial. Like the drop of blood, so tiny and insignificant, except to remind us of that moment of death in time, pure and complete in its spherical glitter.

Another was lucky and survived the assault. Probably he was quick to escape. He minimised into a contracted mass to reduce exposure to danger. Somehow his eyes seem to burry like the Ostrich, a form of self-denial, a way to live through this world of Darwinism, the survival of the fittest.
