Rare
Under 5% of wildlife watchers report a Hazel Leafminer Moth 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.
August to October
In those months about 10% of wildlife watchers report a Hazel Leafminer Moth in Bavarian Forest National Park on a given day, against under 5% in November to July, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Hazel Leafminer Moth sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Bavarian Forest National Park, in our data
Bavarian Forest National Park is the only park on Wallace's Line with enough records to rate Hazel Leafminer Moth sightings: under 5% of wildlife watchers there report one on a given day.
Same order: Lepidoptera
The closest relatives of the Hazel Leafminer Moth that you can see in Bavarian Forest National Park (order Lepidoptera, Butterflies and Moths) are European Peacock Butterfly (about 40%), Common Blue (about 30%) and Meadow Brown (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Hazel Leafminer Moth 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.
