With luck
About 10% of wildlife watchers report a Mallow Skipper sighting in Lyon on a given day, based on 35 verified sightings from GBIF citizen-science data. It is the 76th most-seen of the 411 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
April and August
In those months about 20% of wildlife watchers report a Mallow Skipper in Lyon on a given day, against under 5% in October to February, the lowest months.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Mallow Skipper sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
8th of 23

GBIF citizen-science records
It is estimated from how often the Mallow Skipper is recorded against all the insects logged in Lyon (35 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.
