In the north it extends to south and central England, Ireland, Scandinavia in the areas around the Baltic Sea, in Finland and northern Russia. Largely missing in the Mediterranean with the exception of two smaller occurrences on the French Mediterranean coast and in Tuscany, as well as on the northern Adriatic coast (in northern Italy, Slovenia and Croatia). In south-eastern Europe the distribution area stretches far to the south to northern Albania and northern Greece. From there it runs east (Russian Far East, northern China, Japan, Korea). Also to the south in Bulgaria, Ukraine, Crimea and southern Russia, Central Asia and Siberia.

Rare
Under 5% of wildlife watchers report a Silver Hook sighting in Wadden Sea National Park on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 536th most-seen of the 818 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
June and July
In those months about 10% of wildlife watchers report a Silver Hook in Wadden Sea National Park on a given day, against under 5% in August to May, the lowest months.
Between midnight and 3 am
Across all the parks we cover, that three-hour window holds the most Silver Hook sightings with a recorded time, and about half of them come between 6 am and 6 pm: it is seen both by day and at night.
Only Wadden Sea National Park, in our data
Wadden Sea National Park is the only park on Wallace's Line with enough records to rate Silver Hook sightings: under 5% of wildlife watchers there report one on a given day.
Same genus: Deltote
The closest relatives of the Silver Hook that you can see in Wadden Sea National Park (genus Deltote) are Silver Barred (about 10%) and Marbled White-Spot (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Silver Hook is recorded against all the insects logged in Wadden Sea National Park (8 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.
