This I believe is a Fijian Long Horned beetle and whilst this guy was only 3" long head to body some grow to 6" length. They are supposedly rare and I was lucky to be able to spend over an hour photographing him.
Unfortunately he made me work real hard and was not prepared to stay still very often.
No 1 - One of just three natural light shots I managed
No 2
No 3
No 4 - Relaxing after his photo session
