Aeshna affinis Van der Linden, 1820 ♂
Common names: Southern Migrant Hawker, Blue-eyed Hawker [En], Aeshne affine [Fr], Zuidelijke glazenmaker [Nl], Südliche Mosaikjungfer [De]

IUCN Status: LC (Least Concern)

Küçükbahçe, İZMİR ● Turkey

Description: 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.

Biology: Adults emerge in May and are on the wing until Autumn. After emergence the immature adults move away from water and spend a time feeding and becoming sexually mature. This period will last 10 days to many weeks. Males are often seen patrolling low down whereas A. mixta tends to patrol higher up in the trees. After maturation the males patrol well vegetated ponds and lakes looking for females. The female will be grabbed and the pair will copulate. After sperm is transferred the male A. affinis stays with the female for egg laying which is usually in vegetation. A. affinis is the only European Aeshna to lay its eggs in tandem; the only other European hawker to lay eggs in tandem is Anax parthenope. The laval stage usually lasts two years.

Habitat: This species prefers standing water bodies that dry up over the summer that are often overgrown with low rushes, bulrushes or reeds.

Distribution: Aeshna affinis is found around the Mediterranean, east to Mongolia, north to The Netherlands, Germany, Poland, Belarus and Lithuania; it is scarce in much of Iberia and north Africa. Hot summers can lead to influxes further north; at time of assessment this species had increased its range northwards in the northern most countries.
