With luck
About 10% of wildlife watchers report a Common Grammoptera sighting in London on a given day, based on 197 verified sightings from GBIF citizen-science data. It is the 197th most-seen of the 1504 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
April and May
In those months about 20% of wildlife watchers report a Common Grammoptera in London on a given day, against under 5% in July to March, the lowest months.
Among the best
Of the 16 cities where we can rate Common Grammoptera sightings, London ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Vienna (Austria, about 10%).
Same family: Cerambycidae
The closest relatives of the Common Grammoptera that you can see in London (family Cerambycidae, Longhorn Beetles) are Spotted Longhorn Beetle (about 10%), Fairy-Ring Longhorn Beetle (about 10%) and Lesser Thorn-Tipped Longhorn Beetle (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Common Grammoptera is recorded against all the insects logged in London (197 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.
