Rare
Under 5% of wildlife watchers report a Dotted Border Wave sighting in Berlin on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 949th most-seen of the 1065 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Dotted Border Wave in Berlin on a given day, so our monthly data shows no clear season.
Between 11 pm and 2 am
Across all the parks we cover, that three-hour window holds the most Dotted Border Wave sightings with a recorded time, and nearly all of them come between 6 pm and 6 am: it is mostly seen at night.
Only Berlin, in our data
Berlin is the only city on Wallace's Line with enough records to rate Dotted Border Wave sightings: under 5% of wildlife watchers there report one on a given day.
Same genus: Idaea
The closest relatives of the Dotted Border Wave that you can see in Berlin (genus Idaea) are Small Dusty Wave (about 10%), Riband Wave (about 10%) and Least Carpet (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Dotted Border Wave is recorded against all the insects logged in Berlin (6 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.
