Orb-weaver Spider

Neoscona molemensis

Description:

I am not sure what this spider is doing, especially in the first photo where it appears to be standing on its head. However, I have noticed, on a number of occassions, that when a spider adopts an unusual posture, it might be an indication that it is about to moult, or to lay eggs.

Habitat:

Spotted in the farm on Tropical Whiteweed (Ageratum conyzoides Linn.) known in the Philippines by various names in many dialects. In our local dialect, this plant is called Salunay. Plant information - http://stuartxchange.com/Bulak.html
