The wingspan is 18–22 mm. The moth flies from April to August depending on the location. Cilix glaucata lives on sunny and warm forest edges, slopes and hedges, on bushy dry grasslands and heaths, but also in parks. The moth has porcelain-white wings, with a series of small grey spots along the outside edge of the front wing and the inner edge has a large dark brown stain, which turns yellow and grey towards the middle of the wing.

Rare
Under 5% of wildlife watchers report a Chinese Character sighting in London on a given day, based on 39 verified sightings from GBIF citizen-science data. It is the 578th 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 30%, if each day is a fresh chance.
July and August
In those months about 10% of wildlife watchers report a Chinese Character in London on a given day, against under 5% in September to June, the lowest months.
Between 11 pm and 2 am
Across all the parks we cover, that three-hour window holds the most Chinese Character sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
Yes
Of the 3 cities where we can rate Chinese Character sightings, London has the highest daily chance: under 5%. Next come Prague (Czechia, under 5%) and Vienna (Austria, under 5%).
GBIF citizen-science records
It is estimated from how often the Chinese Character is recorded against all the insects logged in London (39 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.
