The migrant hawker (''Aeshna mixta'') is one of the smaller species of hawker dragonflies. It can be found away from water but for breeding it prefers still or slow-flowing water and can tolerate brackish sites. The flight period is from July to the end of October. ''A. mixta'' occurs in North Africa, southern and central Europe to the Baltic region. ==Identification== ''A. mixta'' is a small ''aeshna'' which appears dark in flight. It is similar in appearance to other aeshnas but has a characteristic "golf-tee" shaped mark on the second segment of the abdommen (S2) which is diagnostic. In flight it looks like a small Emperor dragonfly with a blue abdomen which, when seen from the side, curves down. The main identification problem in the field is distinguishing this species from ''A. affinis'' where the two species fly together. The markings on the side of the thorax are 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.
