Somatochlora metallica
In 3 days ~10% in a week ~20%
The brilliant emerald, Somatochlora metallica, is a middle-sized species of dragonfly. It is the largest and greenest of the Somatochlora species; 50–55 millimetres (2.0–2.2 in) long. S. metallica is found across most of northern Eurasia where it is the commonest of its genus. In Great Britain, it is locally common in south east England and has a very restricted population in Scotland.
The East Asian Somatochlora vera, scientifically described in 1914 by Aleksandr Bartenev based on a specimen from Ussuri, Siberia (and later also reported in northern China), is typically treated as part of S. metallica, but has also been considered a synonym of the East Asian S. exuberata.

Rare
Under 5% of wildlife watchers report a Brilliant Emerald sighting in Pyrénées National Park on a given day, based on 10 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 1144th most-seen of the 1277 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
July
In that month about 10% of wildlife watchers report a Brilliant Emerald in Pyrénées National Park on a given day, against under 5% in August to June, the lowest months.
Between 4 and 7 pm
Across all the parks we cover, that three-hour window holds the most Brilliant Emerald sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Pyrénées National Park, in our data
Pyrénées National Park is the only park on Wallace's Line with enough records to rate Brilliant Emerald sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Brilliant Emerald is recorded against all the insects logged in Pyrénées National Park (10 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.
