With luck
About 10% of wildlife watchers report a Scalloped Hook-Tip sighting in Wadden Sea National Park on a given day, based on 50 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 127th 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 50%, if each day is a fresh chance.
July
In that month about 20% of wildlife watchers report a Scalloped Hook-Tip in Wadden Sea National Park on a given day, against under 5% in September to June, the lowest months.
Between 10 pm and 1 am
Across all the parks we cover, that three-hour window holds the most Scalloped Hook-Tip sightings with a recorded time, and about 9 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Yes
Of the 2 parks where we can rate Scalloped Hook-Tip sightings, Wadden Sea National Park has the highest daily chance: about 10%. Next come Bavarian Forest National Park (Germany, under 5%).

GBIF citizen-science records
It is estimated from how often the Scalloped Hook-Tip is recorded against all the insects logged in Wadden Sea National Park (50 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.
