Acleris cristana, the rufous-margined button moth, is a moth of the family Tortricidae and is found from Europe through the Caucasus and Ussuri to Japan. The wingspan is 18–22 mm. Thorax with strong longitudinal crest. Forewings reddish-ochreous to dark brown,
sometimes bicolorous; a very large sometimes white scale-tuft in middle of disc; sometimes a white or pale ochreous dorsal streak, or an orange central longitudinal streak; sometimes two fascia-like whitish streaks from costa converging to middle of
disc. The hindwings grey, apex darker. It shows a wide variation in appearance and has 137 named forms as well as numerous synonyms. Forms look different but are the same species and can breed together. Julius von Kennel provides a full description.
Adults are on wing from August to November and again from March to May after hibernation. The larvae feed between spun leaves on various rosaceous trees and bushes, including Prunus spinosa and Crataegus species (e.g. Crataegus maximowiczi). Other recorded food plants include Carpinus betulus, Ulmus campestris, Rosa, Malus species (including Malus pumila), Salix caprea, Sorbus sambucifolia, Cerasus sachalinensis, Prunus salicina and Zelkova serrata.

Rare
Under 5% of wildlife watchers report a Tufted Button sighting in London on a given day, based on 13 verified sightings from GBIF citizen-science data. It is the 1005th 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.
November
In that month about 10% of wildlife watchers report a Tufted Button in London on a given day, against under 5% in December to October, the lowest months.
Between 9 pm and midnight
Across all the parks we cover, that three-hour window holds the most Tufted Button 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 2 cities where we can rate Tufted Button sightings, London has the highest daily chance: under 5%. Next come Prague (Czechia, under 5%).
Same genus: Acleris
The closest relatives of the Tufted Button that you can see in London (genus Acleris) are Garden Rose Tortrix (about 10%) and Maple Leaftier Moth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Tufted Button is recorded against all the insects logged in London (13 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.
