Red Driver Ant (Dorylus helvolus)

Can you believe that this wasp-like insect is actually an ant? They are rather large, about 4-5cm (2 1/2 to 3 inches) in body length.
This is male and although vicious looking, they are harmless to humans.
They live in large colonies with the workers which are much smaller and have a mean bite.
 They can often be seen coming to lights at night.

An African winter sunset

Yesterday I found myself on top of a high hill at sunset and took these pictures. Now I have taken pictures of sunsets before but wanted to try something different and came up with these. It is more a play on light, shadow and shapes than actual sunsets. The photographs have not been cropped or manipulated in any way. I am not sure if they are good or bad so would appreciate comments.
