Rare
Under 5% of wildlife watchers report a Lilac Leafminer Moth sighting in Wadden Sea National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 699th 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.
April
In that month about 10% of wildlife watchers report a Lilac Leafminer Moth in Wadden Sea National Park on a given day, against under 5% in May to March, the lowest months. That is one of Wadden Sea National Park's driest months, with about 45 mm of rain against 140 mm in November.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Lilac Leafminer Moth 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 Lilac Leafminer Moth sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Lilac Leafminer Moth is recorded against all the insects logged in Wadden Sea National Park (6 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.
