Finally, able to shoot today at a park! Been really busy for the past weeks! And also finally managed to find and shoot one of my most "wanted" list of insects! the Ant-Like Crab Spider!

Here is some info of this fella from Joseph Koh's "A Guide to Common Singapore Spiders".

"Classification: Family Thomisidae, Crab Spiders
Habitat: Foliage in gardens and secondary jungles where the familiar Kerengga ants can be found.
Female: 6-7 mm.
Distribution: Singapore, Indonesia.

The abdomen imitates the head of the familiar "Kerengga" ant (Oecophylla smaragdina) with the two dark dots simulating the ant's eyes.

The cephalothorax is exaggeratedly arched, giving the impression that it is the abdomen of the ant. The first two pairs of legs are often jerkily held up and down while the spider moves about in an advance-and-halt fashion. It feeds on Kerengga ants at night. On seeing an ant, it pounces on the ant. While holding the ant in its jaws and anchoring itself with a safety line of silk, it falls with the ant. The silken safety line allows the spider to remain suspended in mid-air where the ant has no chance to mount a counter-attack. The ant soon ceases its futile struggle when the venom takes effect.

Crab spiders move sideways, like crabs. The body is not as hairy as in most spiders. They are slow-moving spiders which do not actively hunt like Wolf Spiders. Instead, they remain stationary and await in ambush for some unsuspecting insects to land in front of them. The first two pairs of legs in most Crab Spiders are longer and heavier than the third and fourth pairs, and are armed with spines for holding and grasping prey."

Here are the pics!

Introducing......
#1:The Ant-Like Crab Spider

#3:...and my butt.....Those 'eyes' makes me look like an ant!


#4: And because of my deception, I can get my prey....


#5: ...flies will also share with me...


#6:...and one more little fly coming from under the leaf....


#7:..anyway, I don't care, and I bite my prey at the leg....


#8: And when I am finished, I can present the carcass to you...


#9:....or throw it over the side....


#10: When finished....I go hunting again....and my pose here is typical of a crab spider!


#11: Er...of course, we are not always successful in getting prey....see my "Half" friend here? Something must have happen to it.....
