Celypha rufana, the lakes marble, is a small moth species of the family Tortricidae, long known under the junior synonym C. rosaceana. Junior synonyms of this species are: Argyroploce rufana (Scopoli, 1763) Celypha rosaceana (Schläger, 1848)
The basic color of the forewings is rosy or purplish (hence the Latin species name rosaceana, meaning pinkish) when the moth is freshly emerged, but it turns quickly to a dull buff tinge or a rufous coloration, with a lightly reticulated (net-like) pattern.

Rare
Under 5% of wildlife watchers report a Lakes Marble sighting in London on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 1153rd most-seen of the 1504 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Lakes Marble in London on a given day, so our monthly data shows no clear season.
Among the best
Of the 2 cities where we can rate Lakes Marble sightings, London ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Novosibirsk (Russia, under 5%).
GBIF citizen-science records
It is estimated from how often the Lakes Marble is recorded against all the insects logged in London (10 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.
