May 27, 2007: N. pilipes, A. flavescens and reflections

First to establish the scale of N. pilipes and A. flavescens.

may 27 9736 nephila argyrodes

An accident. I tripped over one of the supporting strands and the top portion of the web collapses. Her is another view of the size scale with the accumulated collapsed web silk

Though the depth of field is not great - here is another size scale comparison

Ventral view

may 27 9662 nephila argyrodes

Here is a mature Argyrodes flavescens (center) and an infant (I think) to the upper right

may 27 9707 argyrodes

Her abdomen is highly polished and here you can see the reflection of the sky. THe little yellow dots on the Nephila silk are caused by the accumulation of water which in turn regulates the tension of the silk. My question, though, is why are not droplets on the radial strands?

Manipulaing the silk

I think she is harvesting water droplets here

She just seems suspended in air here except for her drag line and a small strand that she holds with one of her left fore-legs
