Calopteryx haemorrhoidalis is a species of damselfly in the family Calopterygidae known by the common names copper demoiselle and Mediterranean demoiselle. It is common in much of its range. 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.
The males have a dark, metallic shining body, the color of which can be red... Wikipedia →

With luck
About 10% of wildlife watchers report a Copper Demoiselle sighting in Lisbon on a given day, based on 43 verified sightings from GBIF citizen-science data. It is the 87th most-seen of the 441 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
May to August
In those months about 10% of wildlife watchers report a Copper Demoiselle in Lisbon on a given day, against under 5% in September to April, the lowest months. Those are among Lisbon's driest months, with about 15 mm of rain a month against 95 mm in November.
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.
Among the best
Of the 6 cities where we can rate Copper Demoiselle sightings, Lisbon ranks 3rd at about 10%, level with the leaders once rounded. The best odds are in Porto (Portugal, about 10%) and Rome (Italy, about 10%).
Same order: Odonata
The closest relatives of the Copper Demoiselle that you can see in Lisbon (order Odonata, Dragonflies and Damselflies) are Nomad (about 10%), Broad Scarlet (about 10%) and Iberian Bluetail (about 10%), 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 Lisbon (43 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.
