Tonight I was looking through some pictures taken about 10 years ago and found these interesting pictures from Alviso Adobe Park in Pleasanton, California.
I always enjoy seeing lone oak trees when I travel through the hill country of California. I really like the shadows thrown by the branches of this oak tree. This tree is close to the Alviso Adobe Park.
I believe that this is a red-backed jumping spider (Phidippus johnsoni). This would be a female because of the black stripe on the back. These spiders are not very big, but they can jump a distance about five times their length.
The background is the leaf of a large cactus. If you know how small the spacing of the areoles are on a cactus then you can get an idea of how small the spider is.
This is a small sampling of the pictures I have taken in the park, I may have to share more later.
I hope you liked this little look at nature.
