Migrant Hawker

Aeshna mixta

This record describes Aeshna mixta (species). Recorded family: Aeshnidae. Recorded order: Odonata.

Identification and Appearance

Migrant Hawker - Aeshna mixta

This is a medium sized dragonfly. The overall impression is dark, the male having a blackish abdomen with blue spots, brown thorax with relatively narrow yellow stripes, and blue eyes. Females are brown with yellow spots. Both sexes have a prominent yellow 'golf tee' triangle on abdominal segment 2. The Common Hawker is similar but is larger and lacks the golf tee mark at the top of the abdomen. The Migrant Hawker breeds in a variety of well vegetated aquatic habitats and is often also recorded well away from water along hedgerows and woodland edges. Before the 1940's it was, as the name suggests, a migrant visitor but now it is an established breeding species in the UK. Most British records come from England south of the Humber. Prior to the 1980s historic records show that this species was, as its name suggests, a migrant to VC 55. From the 1980s onwards, however, the Migrant Hawker has become a widespread species and a familiar sight during its late summer flight period; owing to this late emergence it is still probably under recorded as most observers of Odonata are most active in the early to mid summer periods. The Migrant Hawker breeds in a variety of well vegetated aquatic habitats and is often also recorded well away from water.

About Dragonflies and Damselflies: the wider group

Order-level background for Odonata, the group containing Aeshna mixta. Species-specific details appear above.

Group overview

Odonata includes ~6,000 described species of dragonflies and damselflies. Dragonflies are among the fastest flying insects, reaching 36 mph (58 km/h). They can fly in any direction including backward, and hover in place - each wing operates independently.

Ecological role of the group

Dragonflies predate dinosaurs by nearly 100 million years - fossils date to 325 million years ago. The largest dragonfly ancestor, Meganeuropsis permiana (285 mya), had a 75cm wingspan, enabled by atmospheric oxygen levels of 31-35% compared to today's 21%. Dragonflies have a 95% hunting success rate - the highest of any predator.

Economic and practical significance of the group

Dragonflies are voracious predators that consume hundreds of mosquitoes daily, providing natural pest control worth millions in reduced mosquito-borne disease risk. A single dragonfly can eat 30 to hundreds of mosquitoes per day.
