In 3 days ~50% in a week ~80%
Trithemis annulata, commonly known as the violet dropwing, violet-marked darter, purple-blushed darter, or plum-coloured dropwing, is a species of dragonfly in the family Libellulidae. It is found in most of Africa, the Middle East, and southern Europe. These dragonflies are called dropwings because of their habit of immediately lowering their wings after landing on a perch. Males of this species are violet-red with red veins in the wings, while females are yellow and brown. Both sexes have red eyes. Wikipedia →

Possible
About 20% of wildlife watchers report a Violet Dropwing sighting in Algiers on a given day, based on 44 verified sightings from GBIF citizen-science data. It is the 16th most-seen of the 133 insects we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
September
In that month about 40% of wildlife watchers report a Violet Dropwing in Algiers on a given day, against under 5% in October and December–April, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Violet Dropwing sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
7th of 23
Of the 23 cities where we can rate Violet Dropwing sightings, Algiers ranks 7th at about 20%. The best odds are in Dammam (Saudi Arabia, about 50%), Antalya (Turkey, about 40%) and Ouagadougou (Burkina Faso, about 40%).
GBIF citizen-science records
It is estimated from how often the Violet Dropwing is recorded against all the insects logged in Algiers (44 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.
