With luck
About 10% of wildlife watchers report a Small Red-Eyed Damselfly sighting in Jerusalem on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 112th most-seen of the 137 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
May and June
In those months about 20% of wildlife watchers report a Small Red-Eyed Damselfly in Jerusalem on a given day, against under 5% in July to April, the lowest months. Those are among Jerusalem's driest months, with almost no rain against 90 mm in January.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Small Red-Eyed Damselfly sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 24 cities where we can rate Small Red-Eyed Damselfly sightings, Jerusalem ranks 3rd at about 10%, level with the leaders once rounded. The best odds are in Brussels (Belgium, about 10%) and Rostov-on-Don (Russia, about 10%).
GBIF citizen-science records
It is estimated from how often the Small Red-Eyed Damselfly is recorded against all the insects logged in Jerusalem (5 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.
