The emperor dragonfly or blue emperor (Anax imperator) is a large species of hawker dragonfly of the family Aeshnidae. It is the largest dragonfly in most of Europe, including the United Kingdom, although exceeded in some areas by other species.
The generic name Anax is from the ancient Greek ἄναξ, "lord"; the specific epithet imperator is the Latin for "emperor", from imperare, to command. This dragonfly has a wide distribution through Afroeurasia; it is found throughout Africa and through most of Europe, the Arabian Peninsula, and south-western and central Asia. Since the 1990s, its range has expanded in Europe, both northwards and to higher altitudes. For example, the first Scandinavian record was in 1994 in Denmark; in 2002 it was first recorded in Sweden and in 2004 first in Scotland; today it is regular in all three countries. The species' northward expansion has been tied to global warming, and it is among the first odonata to do so.
The emperor dragonfly is a large and bulky species. It is 73–82 mm (2.9–3.2 in) long, with average being 78 mm (3.1 in) and males growing larger than females. The average wingspan is 104... Wikipedia →

With luck
About 10% of wildlife watchers report a Blue Emperor sighting in Table Mountain National Park on a given day, based on 80 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 68th most-seen of the 344 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
October to April
In those months about 10% of wildlife watchers report a Blue Emperor in Table Mountain National Park on a given day, against under 5% in May to September, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Blue Emperor sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
12th of 15
Of the 15 parks where we can rate Blue Emperor sightings, Table Mountain National Park ranks 12th at about 10%. The best odds are in Plitvice Lakes National Park (Croatia, about 20%), iSimangaliso Wetland Park (South Africa, about 20%) and Mercantour National Park (France, about 10%).
GBIF citizen-science records
It is estimated from how often the Blue Emperor is recorded against all the insects logged in Table Mountain National Park (80 verified sightings from 2019 to 2026), 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.
