Rare
Under 5% of wildlife watchers report an Anomalous sighting in Cairngorms National Park on a given day, based on 9 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 300th most-seen of the 300 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
In that month about 10% of wildlife watchers report an Anomalous in Cairngorms National Park on a given day, against under 5% in September to July, the lowest months.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Anomalous sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Cairngorms National Park, in our data
Cairngorms National Park is the only park on Wallace's Line with enough records to rate Anomalous sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Noctuidae

GBIF citizen-science records
It is estimated from how often the Anomalous is recorded against all the insects logged in Cairngorms 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.
