With luck
About 10% of wildlife watchers report a Chocolate-Tip sighting in Wadden Sea National Park on a given day, based on 22 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 261st most-seen of the 818 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.
April–June and August
In those months about 10% of wildlife watchers report a Chocolate-Tip in Wadden Sea National Park on a given day, against under 5% in July and September–March, the lowest months.
Between 5 and 8 am
Across all the parks we cover, that three-hour window holds the most Chocolate-Tip sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 3 parks where we can rate Chocolate-Tip sightings, Wadden Sea National Park has the highest daily chance: about 10%. Next come Bavarian Forest National Park (Germany, about 10%) and Pyrénées National Park (France, under 5%).
GBIF citizen-science records
It is estimated from how often the Chocolate-Tip is recorded against all the insects logged in Wadden Sea National Park (22 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.
