The cream wave (Scopula floslactata) is a moth of the family Geometridae. The species was first described by Adrian Hardy Haworth in 1809. It is found in forest and woodland regions, feeding on grasses and small plants such as dandelion.
It is a very common species in parts of France and central Europe. The range in the north extends to Scandinavia and Finland. The species is largely missing in southern Europe. There are isolated occurrences in southern Bulgaria and the Pyrenees). It extends east across the Palearctic from the Urals to the Russian Far East (Sakhalin) to Korea, north-eastern China and Japan.
Scopula floslactata has a wingspan of about three centimetres. Colour and pattern are variable. The wings are creamy white to yellowish white. Across the forewings and hindwings, there are usually three jagged crosslines. Occasionally, there is a wavy line in the marginal field. The discal flecks are small and are often missing on the forewings, or very much blurred. In contrast, the discal flecks on the hindwings are almost always present. The fringes are sometimes also slightly darker than the ground colour. The males have small, feathered... Wikipedia →

Rare
Under 5% of wildlife watchers report a Cream Wave sighting in Helsinki on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 732nd most-seen of the 838 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.
June
In that month about 10% of wildlife watchers report a Cream Wave in Helsinki on a given day, against under 5% in July to May, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Cream Wave sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 2 cities where we can rate Cream Wave sightings, Helsinki has the highest daily chance: under 5%. Next come Moscow (Russia, under 5%).
GBIF citizen-science records
It is estimated from how often the Cream Wave is recorded against all the insects logged in Helsinki (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.
