Rare
Under 5% of wildlife watchers report a Dwarf Cream Wave sighting in Prague on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 543rd most-seen of the 724 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
July
In that month about 10% of wildlife watchers report a Dwarf Cream Wave in Prague on a given day, against under 5% in August to June, the lowest months. That is one of Prague's wettest months, with about 80 mm of rain against 30 mm in February.

Across all the parks we cover, that three-hour window holds the most Dwarf Cream Wave 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.

Same genus: Idaea

GBIF citizen-science records
It is estimated from how often the Dwarf Cream Wave is recorded against all the insects logged in Prague (7 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.
