Rare
Under 5% of wildlife watchers report an August Thorn sighting in Munich on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 295th most-seen of the 521 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 August
In those months about 10% of wildlife watchers report an August Thorn in Munich on a given day, against under 5% in July and September–May, the lowest months. Those are among Munich's wettest months, with about 140 mm of rain a month against 60 mm in February.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most August Thorn 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.
3rd of 7
Of the 7 cities where we can rate August Thorn sightings, Munich ranks 3rd at under 5%. The best odds are in Kharkiv (Ukraine, about 10%) and London (United Kingdom, about 10%).
Same family: Geometridae
The closest relatives of the August Thorn that you can see in Munich (family Geometridae, Geometer Moths) are Small Dusty Wave (about 10%), Winter Moth (about 10%) and Yellow Shell Moth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the August Thorn is recorded against all the insects logged in Munich (8 verified sightings), 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.
