My first post has to be of one of my favourite adder photographs!
I photographed this juvenile female adder in 2010. She was tucked under a small leaf and was quite hard to spot as she blended in with her habitat remarkably well.
Judging by her size (not much bigger than a two pound coin), she is probably one year old.
Photographed using a Canon eos 7d and Canon 100mm f/2.8 macro lens.
