In short: With a wingspan reaching 110 millimetres, the Southern Hawker is an imposing presence in European skies. Despite their predatory reputation and territorial mid-air brawls, these dragonflies are entirely harmless to humans. Their curious nature often leads them to investigate people, making them a common sight in gardens and parks.

The Southern Hawker, known scientifically as Aeshna cyanea, is one of the most widespread dragonflies across the Western Palearctic. Its range stretches from Ireland in the west to the Ural Mountains in the east, and from Scotland and southern Scandinavia down to Italy and the northern Balkans. While they are most frequently associated with small, well-vegetated ponds, these insects are highly mobile and frequently wander into open woodlands, parks, and even populated streets far from their breeding grounds.

Physically, the species is striking. Adults can grow to 70 millimetres in length, featuring a brown thorax marked by two wide, green longitudinal stripes and a distinctive T-shaped black spot on the forehead. Sexual dimorphism is pronounced: males display a dark abdomen with bright apple-green markings that transition to joined pale blue segments at the tip, while females possess a brownish abdomen with green accents. Their flight season typically runs from June through October, though individuals may appear as early as May or as late as November.

Their life cycle is a multi-year process. Females deposit eggs by jabbing their abdomens into rotting wood or vegetation, where the eggs remain until hatching the following spring. The resulting nymphs are voracious aquatic predators, feeding on tadpoles, small fish, and invertebrates. After two to three years of development, they emerge as adults in July or August. During the breeding season, males become intensely territorial, patrolling water edges and engaging in dramatic aerial combat with rivals, spiralling through the air to defend their space. Despite their size and aggressive displays toward other dragonflies, they lack stingers and pose no threat to humans, often displaying a level of inquisitiveness that brings them close to observers without ever turning to aggression.
