Rare
Under 5% of wildlife watchers report a Short-Barred Marble sighting in Wadden Sea National Park on a given day, based on 9 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.
August
In that month about 10% of wildlife watchers report a Short-Barred Marble in Wadden Sea National Park on a given day, against under 5% in September to July, the lowest months.
Between 11 pm and 2 am
Across all the parks we cover, that three-hour window holds the most Short-Barred Marble sightings with a recorded time, and nearly all of them come between 6 pm and 6 am: it is mostly seen 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 Short-Barred Marble sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Short-Barred Marble is recorded against all the insects logged in Wadden Sea National Park (9 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.
