Rare
Under 5% of wildlife watchers report a Marsh Dowd sighting in London on a given day, based on 30 verified sightings from GBIF citizen-science data. It is the 660th most-seen of the 1504 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
July and August
In those months about 10% of wildlife watchers report a Marsh Dowd in London on a given day, against under 5% in September to June, the lowest months.
Only London, in our data
London is the only city on Wallace's Line with enough records to rate Marsh Dowd sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Marsh Dowd is recorded against all the insects logged in London (30 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.
