Rare
Under 5% of wildlife watchers report a Welsh Oak Longhorn Beetle sighting in Wadden Sea National Park on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 536th 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 and May
In those months about 10% of wildlife watchers report a Welsh Oak Longhorn Beetle in Wadden Sea National Park on a given day, against under 5% in June to March, the lowest months. Those are among Wadden Sea National Park's driest months, with about 45 mm of rain a month against 140 mm in November.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Welsh Oak Longhorn Beetle sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 3 parks where we can rate Welsh Oak Longhorn Beetle sightings, Wadden Sea National Park ranks 3rd at under 5%, level with the leaders once rounded. The best odds are in Cévennes National Park (France, under 5%) and Pyrénées National Park (France, under 5%).

GBIF citizen-science records
It is estimated from how often the Welsh Oak Longhorn Beetle is recorded against all the insects logged in Wadden Sea National Park (8 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.
