Rare
Under 5% of wildlife watchers report a Zircon Reed Beetle sighting in Helsinki on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 665th most-seen of the 838 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.
June
In that month about 10% of wildlife watchers report a Zircon Reed Beetle in Helsinki on a given day, against under 5% in July to May, the lowest months.
Only Helsinki, in our data
Helsinki is the only city on Wallace's Line with enough records to rate Zircon Reed Beetle sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Chrysomelidae
The closest relatives of the Zircon Reed Beetle that you can see in Helsinki (family Chrysomelidae, Leaf Beetles) are Alder Leaf Beetle (about 20%), Western Grape Rootworm (about 10%) and Chrysolina sanguinolenta (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Zircon Reed Beetle is recorded against all the insects logged in Helsinki (6 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.
