Rare
Under 5% of wildlife watchers report a Red-Eyed Damselfly sighting in Bavarian Forest National Park on a given day, based on 7 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 822nd most-seen of the 1115 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.
May and June
In those months about 10% of wildlife watchers report a Red-Eyed Damselfly in Bavarian Forest National Park on a given day, against under 5% in July to April, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Red-Eyed Damselfly sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 3
Of the 3 parks where we can rate Red-Eyed Damselfly sightings, Bavarian Forest National Park ranks 2nd at under 5%. The best odds are in Biebrza National Park (Poland, about 20%).
GBIF citizen-science records
It is estimated from how often the Red-Eyed Damselfly is recorded against all the insects logged in Bavarian Forest National Park (7 verified sightings from 2019 to 2026), 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.
