Anax guttatus is definitely a beautiful aeshnid species as the blue marking on the abdomen is striking. It is normally found at open pond and active during day time. There are two Anax species in Peninsular Malaysia - A. guttatus and A. panybeus. Both the species are quite difficult to tell apart. Close inspection on anal appendages and length of 3rd abdominal segment is neccessary to disitinguish them. However, A. panybeus is much less common in Peninsular Malaysia.
