Photo taken in my backyard, and edited slightly in the GIMP.
Caelifera is the scientific suborder of the grasshopper.
This is the light version, get the darker version here: http://gnome-look.org/content/show.php?content=153705
The wallpaper comes in 3 aspect ratios, 16:9, 16:10, and 4:3.
Use whatever one matches your screen resolution, it should scale.
