Since 2003 this African tropical dragonfly has been colonizing Europe helped by a widespread increase in temperatures. It is now breeding successfully in Spain, Portugal and France. The adult male abdomen measures 21–24 mm and hind wing 24–27 mm. Female abdomen measures 23 mm and hind wing 26–30 mm. The male is a medium-sized scarlet dragonfly with a broad reddish amber patch on the base of transparent wings. The female is similar to the male, but duller in color. Its natural habitats are subtropical or tropical streams... Wikipedia →

Possible
About 20% of wildlife watchers report an Orange-Winged Dropwing sighting in Algiers on a given day, based on 16 verified sightings from GBIF citizen-science data. It is the 37th most-seen of the 133 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
August
In that month about 40% of wildlife watchers report an Orange-Winged Dropwing in Algiers on a given day, against under 5% in October to April, the lowest months. That is one of Algiers's driest months, with about 15 mm of rain against 90 mm in November.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Orange-Winged Dropwing 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 14
Of the 14 cities where we can rate Orange-Winged Dropwing sightings, Algiers ranks 4th at about 20%. The best odds are in Lusaka (Zambia, about 30%), Marrakesh (Morocco, about 20%) and Harare (Zimbabwe, about 20%).
GBIF citizen-science records
It is estimated from how often the Orange-Winged Dropwing is recorded against all the insects logged in Algiers (16 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.
