With luck
About 10% of wildlife watchers report a Cypress Carpet sighting in London on a given day, based on 81 verified sightings from GBIF citizen-science data. It is the 357th most-seen of the 1504 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.
October
In that month about 20% of wildlife watchers report a Cypress Carpet in London on a given day, against under 5% in July–August and December–April, the lowest months.
Only London, in our data
London is the only city on Wallace's Line with enough records to rate Cypress Carpet sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Cypress Carpet is recorded against all the insects logged in London (81 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.
