Rare
Under 5% of wildlife watchers report a Scalloped Hook-Tip sighting in Bavarian Forest National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 964th 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.
April and July–August
In those months about 10% of wildlife watchers report a Scalloped Hook-Tip in Bavarian Forest National Park on a given day, against under 5% in May–June and September–March, 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.
2nd of 2
Of the 2 parks where we can rate Scalloped Hook-Tip sightings, Bavarian Forest National Park ranks 2nd at under 5%. The best odds are in Wadden Sea National Park (Germany, about 10%).
Same family: Drepanidae
The closest relatives of the Scalloped Hook-Tip that you can see in Bavarian Forest National Park (family Drepanidae, Hooktip and False Owlet Moths) are Peach Blossom Moth (about 10%), Pebble Hook-Tip (about 10%) and Buff Arches (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Scalloped Hook-Tip is recorded against all the insects logged in Bavarian Forest National Park (5 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.
