Fellow Arachnophiles

 Here's today's photo of my front-yard spider, poised to capture any bug that lands on the daisy to eat some pollen or nectar.  She spend the whole hot afternoon hanging upside down beneath the flower, then got back on top around 5:00 when it cooled off.
Here's a photo of the yellow phase of the same species of spider from my archives.  I haven't seen one turn yellow yet this season.  It takes several days for them to change color, and I am curious about what conditions trigger the change.  There have been some interesting studies of the phenomenon, and it appears not to be for camouflage.  It is more likely they are trying to resemble a flower, thus being a trap for any pollen-eaters that mistake them for flowers.
