Rare
Under 5% of wildlife watchers report a Xylotrechus smei sighting in Cévennes National Park on a given day, based on 16 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 814th most-seen of the 996 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.
June and July
In those months about 10% of wildlife watchers report a Xylotrechus smei in Cévennes National Park on a given day, against under 5% in August to May, the lowest months. Those are among Cévennes National Park's driest months, with about 60 mm of rain a month against 260 mm in October.
Between 10 pm and 1 am
Across all the parks we cover, that three-hour window holds the most Xylotrechus smei sightings with a recorded time, and about 8 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Only Cévennes National Park, in our data
Cévennes National Park is the only park on Wallace's Line with enough records to rate Xylotrechus smei sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Xylotrechus smei is recorded against all the insects logged in Cévennes National Park (16 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.
