It lives along rivers and streams, but also in sunny larger waters. Though it may be affected by habitat changes such as water pollution. Calopteryx haemorrhoidalis can reach a body length of about 45–48 millimetres (1.8–1.9 in). The abdomen length is of about 34–43 millimetres (1.3–1.7 in) in males, of 31–43 millimetres (1.2–1.7 in) in females. The length of the wings is of 23–32 millimetres (0.91–1.26 in) in males, of 25–37 millimetres (0.98–1.46 in) in the females.

Rare
Under 5% of wildlife watchers report a Copper Demoiselle sighting in Barcelona on a given day, based on 12 verified sightings from GBIF citizen-science data. It is the 229th most-seen of the 381 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
July to September
In those months about 10% of wildlife watchers report a Copper Demoiselle in Barcelona on a given day, against under 5% in October to June, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Copper Demoiselle sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
4th of 6
Of the 6 cities where we can rate Copper Demoiselle sightings, Barcelona ranks 4th at under 5%. The best odds are in Porto (Portugal, about 10%), Rome (Italy, about 10%) and Lisbon (Portugal, about 10%).
Same order: Odonata
The closest relatives of the Copper Demoiselle that you can see in Barcelona (order Odonata, Dragonflies and Damselflies) are Nomad (about 20%), Broad Scarlet (about 20%) and Black-Tailed Skimmer (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Copper Demoiselle is recorded against all the insects logged in Barcelona (12 verified sightings), 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.
