Seen in a residential building. Fairly big one.
Found this spider by the edge of a stream. She was waiting for the hapless victim - a struggling insect, a small fish or a tadpole.
There were many Water Striders( Gerridae) all around her. I was eagerly waiting for the her to catch a Water Strider which would sometimes come very close to her. But she didn't seem to be interested in them. I waited for more than 30 mins before I had to move on.
Maybe next time :-)
When I saw this my first impression was it is a caterpillar. On close watch I found this spider is making a caterpillar impression by sitting on the both edged of this silk roll. This is on a bonsai ficus tree.
I am sorry for this poor images.
