''Aeshna affinis'', the southern migrant hawker or blue-eyed hawker, is a dragonfly found in southern Europe and Asia. It is in the family Aeshnidae and is very similar in appearance to ''A. mixta''. ==Identification== ''A. affinis'' is a small ''Aeshna'' and very similar to the related ''A. mixta'' with which it is easily confused. As its name suggests the male has blue eyes and also blue marking on the abdomen. ''A. affinis'' lacks the yellow T-shaped mark which is found on the top of the second abdomen segment in ''A. mixta''. The markings on the side of the thorax are also different in ''A. affinis'' and ''A. mixta''. In ''A. affinis'' the sides of the thorax are greeny yellow with fine black lines along the sutures. In ''A. mixta'' the sides of the thorax are similar in colour but the yellow is separated by dark brown areas so it gives the appearance of having two broad yellow stripes
