UK STATUS NOT EVALUATED IUCN Red List: Least Concern

The smallest hawker dragonfly in the UK, and one belonging to it's own monotypic genus.  It is one of the first dragonfly species to emerge in the UK, first appearing in May, and it's range is increasing Northwards, potentially as a consequence of Climate Change.

Migrant Hawker (Aeshna mixta)

OTHER NAMES: Autumn Hawker
Latin Etymology: Aeshna (?) mixta ("mixed")
Adult Migrant Hawker (subspecies A. m. mixta) at Elmley Marshes, Kent - September 2012

Featured Subspecies: Aeshna mixta mixta
Length: 63mm  /  Wingspan: 87mm
UK Status: Not Evaluated IUCN Red List: Least Concern

A bit less common than some of the other similar looking dragonfly species found in the UK, the migrant hawker only took up residence in the UK in the 20th Century, possibly as temperature have increased, and has slowly been expanding Northwards, reaching Ireland and the Isle of Mann since the beginning of the 21st Century.  This individual was seen near the edge of Elmley Marshes, heading along the Swale back towards Faversham.  The best identifying feature is the "golf-tee" shaped marking just behind the wings, which no other species in the UK has.

Order: Odonata
Family: Aeshnidae
Genus: Aeshna
SUBSPECIES: A. m. mixta, A. m. soneharai

- Sighting Locations -
UNITED KINGDOM A resident species to the South of England which is seen in Summer
 - Seen in Elmley Marshes.

Brown Hawker (Aeshna grandis)

OTHER NAMES: Hairy Dragonfly, Spring Hawker, Amber-winged Hawker
Latin Etymology: Aeshna (?) grandis ("large")


Adult Brown Hawker (Aeshna grandis) at Peterborough - Summer 2022

Featured Subspecies: N/A
Length: 73mm  /  Wingspan: 102mm
UK Status: Not Evaluated IUCN Red List: Least Concern

Probably just about the easiest British Dragonfly to identify in the field - even in flight its rust-bronze wings are distinctive, along with its similarly coloured body and blue or lime green spots.  Found throughout much of Europe, and much of England in particular, I have found this a fairly easy species to see, often patrolling forest ridings, but they seem to be even more flighty than most dragonflies, and thus harder to photograph without something between you and them.

Related Species:
Order: Odonata
Family: Aeshnidae
Genus: Aeshna
SUBSPECIES: None - monotypic

Emperor Dragonfly (Anax imperator)

OTHER NAMES: Blue Emperor
Latin Etymology: Anax (?) imperator ("emperor")
Adult Emperor Dragonfly (subspecies A. i. imperator) at Wellingborough, Northants - June 2016

Featured Subspecies: Anax imperator imperator
Length: 76mm  /  Wingspan: 106mm
UK Status: Not Evaluated IUCN Red List: Least Concern

The largest of the British dragonflies, and as such, arguably the most powerful insect predator in the country. Emperor Dragonflies are fairly widespread throughout the Summer months.  As nymphs, they are able to feed on small vertebrates such as tadpoles and small fish, while as adults they are able to take larger insects such as butterflies and smaller dragonfly species.  The female markings seen on this individual are green on females.

Related Species:
Order: Odonata
Family: Aeshnidae
Genus: Anax
SUBSPECIES: A. i. mauricianus, A. i. imperator

UK Status: Not Evaluated IUCN Red List: Least Concern


Southern Hawkers are one of the larger common species of dragonfly found in the UK, they are found over slow moving or still water and can often be found in woodland, as with this one.  While common over much of Europe, the North African population is considered Endangered.

Lake Darner (Aeshna eremita)

OTHER NAMES: N/A
Latin Etymology: Aeshna (possibly from "spear") eremita ("hermit")

Adult Lake Darner (Aeshna eremita) )at Anchorage, Alaska - August 2024


Featured Subspecies: N/A
Weight: ?  /  Length: 7.5cm  /  Wingspan: 15cm
NO UK STATUS IUCN Red List: Not Yet Evaluated 

The largest "darner" dragonfly of North America, found in the Northern of the Lower 48 through to Canada and Alaska. This species prefers a slightly more wooded habitat that many dragonfly species which matches where I saw it in a forested clearing in Anchorage. It is closely related to the Canada Darner but it's range extends much further North.

Related Species:
Order: Odonata
Family: Aeshnidae
Genus: Aeshna
SUBSPECIES: none - monotypic
