With luck
About 10% of wildlife watchers report a Strophosoma capitatum sighting in Helsinki on a given day, based on 21 verified sightings from GBIF citizen-science data. It is the 292nd most-seen of the 838 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.
May–July and September
In those months about 10% of wildlife watchers report a Strophosoma capitatum in Helsinki on a given day, against under 5% in August and October–April, the lowest months.
Yes
Of the 5 cities where we can rate Strophosoma capitatum sightings, Helsinki has the highest daily chance: about 10%. Next come Warsaw (Poland, about 10%) and Berlin (Germany, under 5%).
Same family: Curculionidae
The closest relatives of the Strophosoma capitatum that you can see in Helsinki (family Curculionidae, True Weevils) are Black Vine Weevil (about 10%), Green Immigrant Leaf Weevil (about 10%) and Common Leaf Weevil (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Strophosoma capitatum is recorded against all the insects logged in Helsinki (21 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.
