This was taken while I was riding my bike along a trail. This shot is particularly interesting in the fact that I did not look through the viewfinder. It was to close to the ground to do so. So I just pointed and shot while hoping for the best. This is the result. :Ð

I have no idea what insect that is however, I didn't even know it was there until after the picture was taken. xÐ
