Rare
Under 5% of wildlife watchers report a Thicket Twist sighting in Wadden Sea National Park on a given day, based on 10 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 486th 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 30%, if each day is a fresh chance.
July and August
In those months about 10% of wildlife watchers report a Thicket Twist in Wadden Sea National Park on a given day, against under 5% in September to June, the lowest months.
Between 10 pm and 1 am
Across all the parks we cover, that three-hour window holds the most Thicket Twist sightings with a recorded time, and about 9 in 10 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 Thicket Twist sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Thicket Twist is recorded against all the insects logged in Wadden Sea National Park (10 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.
