With luck
About 10% of wildlife watchers report a Calamobius filum sighting in Madrid on a given day, based on 23 verified sightings from GBIF citizen-science data. It is the 173rd most-seen of the 457 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
March to May
In those months about 10% of wildlife watchers report a Calamobius filum in Madrid on a given day, against under 5% in June to February, the lowest months.

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.

GBIF citizen-science records
It is estimated from how often the Calamobius filum is recorded against all the insects logged in Madrid (23 verified sightings), 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.
