Bird Dung Spider (Phrynarachne ceylonica) in Sumatra Indonesia


Yes, there is nothing special about the photo above. This photo was taken in Bengkulu Sumatra Indonesia. All you can see is one big leaf  and two smaller leaves and...a drop of bird's droppings?. With that yellow and black color, surely it looks like a bird droppings !

If we look closer to this droppings, something interesting would reveal. Looks like this droppings or dung is no ordinary dung. The structure is so symmetrical that no dung would have it. And now we can see that this is a living creature. This is a spider...or we can say a bird dung spider. 


The question follows the fact. Why is this spider doing such a disgusting disguising?. Well, according the logic of animals( wait...do animals have a logic?), when things look similar to a dung so it must be a dung. Then, all animal such as insect predators will avoid to touch it or even eat it...this is so disgusting to them (in logic of insect eaters). But for the dung-ers and dung lovers such as flies and ants, the unexpected encounter with dungs will bring them joyfulness to approach the dungs and will not aware for whatever the unexpected danger hidden behind them. And that what exactly the logic that is possessed by this kind of spider. Just thinks about the result, no matter how shame the camouflage would seems!


According to its taxonomy, this spider is belong to the family of Thomisidae under genus of Phrynarachne. The most similar species name for the spider above is Phrynarachne ceylonica.
