With luck
About 10% of wildlife watchers report a Calamobius filum sighting in Camargue on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 56th most-seen of the 75 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
April
In that month about 20% of wildlife watchers report a Calamobius filum in Camargue on a given day, against under 5% in June to March, the lowest months.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Calamobius filum sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Camargue, in our data

Same family: Cerambycidae

GBIF citizen-science records
It is estimated from how often the Calamobius filum is recorded against all the insects logged in Camargue (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.
