Bird-dropping Spider - Cyrtarachne inaequalis

At first glance you would not think that this is a spider, but it is! It is scientifically named Cyrtarachne inaequalis (Araneae - Araneidae) and is a species of orb-weaving spider which is commonly known as Bird-dropping Spider because ... this is precisely what they seem.

Spiders of the genus Cyrtarachne are known to feed mainly on moths. Webs of these spiders have several unique characteristics: they are horizontal, have widely spaced spiral thread, the spiral thread has low shear joint (one end of a spiral connected to a radius breaks easily), and the viscid "spanning" threads are coated with a unique glue capable of adhering to moths.

This species was first described from Burma, and has been recorded from China, Japan and Korea.
