Rare
Under 5% of wildlife watchers report a Yellow Rose Button sighting in Moscow on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 992nd most-seen of the 1111 insects we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Yellow Rose Button in Moscow on a given day, so our monthly data shows no clear season.
Between 11 pm and 2 am
Across all the parks we cover, that three-hour window holds the most Yellow Rose Button sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is most active around dawn and dusk.
Only Moscow, in our data
Moscow is the only city on Wallace's Line with enough records to rate Yellow Rose Button sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Yellow Rose Button is recorded against all the insects logged in Moscow (5 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.
