I found this spider just outside my front door. It stayed there for a few days while it was raining and then disappeared again. It had a very messy web, more like a retreat web.
It looks just like a daddy long legs, but its body is a striking gold with black markings. It is the same size as a daddy long legs too, but I can't find anything about gold species online.
I'm in Marrickville in Sydney, Australia and have never seen a spider like that before!
