Rare
Under 5% of wildlife watchers report a Common Sedge-Sawfly sighting in Cologne on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 174th most-seen of the 235 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.
May and July–August
In those months about 10% of wildlife watchers report a Common Sedge-Sawfly in Cologne on a given day, against under 5% in June and September–April, the lowest months.
Between 3 and 6 pm
Across all the parks we cover, that three-hour window holds the most Common Sedge-Sawfly sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 7 cities where we can rate Common Sedge-Sawfly sightings, Cologne ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Rotterdam [The Hague] (Netherlands, under 5%).
GBIF citizen-science records
It is estimated from how often the Common Sedge-Sawfly is recorded against all the insects logged in Cologne (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.
