The migrant hawker or autumn 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 middle of November. A. mixta occurs in North Africa, southern and central Europe to southern Scandinavia and the Baltic region.
A. mixta is a small Aeshna which appears dark in flight. It is similar in appearance to other Aeshna species but has a characteristic "golf-tee" shaped mark on the second segment of the abdomen (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... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Migrant Hawker is recorded against all the insects logged in Manchester (12 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
