Ptycholoma lecheana, the Leche's twist moth, is a moth of the family Tortricidae. It is found in Europe, China (Heilongjiang, Jilin, Hunan), Korea, Japan, Russia (Amur, Ussuri) and Asia Minor. The wingspan is 16–20 mm. The forewings have the termen nearly straight, rather oblique, and a strong costal fold from the base to the middle. The ground colour is dark fuscous, more or less densely irrorated or suffused with ferruginous-ochreous. The edges of the central fascia and the apex of the costal patch are more or less defined by leaden -metallic lines. The hindwings are blackish-grey. The larva is light green, above blackish-green; spots pale; head light brown.
The moth flies from late May to early June in China and to July in western Europe. The larvae feed on various trees and shrubs, including Acer, Betula, Crataegus pinnatifida, Fagus, Larix leptolepis, Populus, Prunus padus, Pyrus, Quercus, Salix koreensis, Sorbus, Tilia and Ulmus species.

Rare
Under 5% of wildlife watchers report a Brindled Tortrix sighting in London on a given day, based on 11 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.
May
In that month about 10% of wildlife watchers report a Brindled Tortrix in London on a given day, against under 5% in June to April, the lowest months.
Among the best
Of the 8 cities where we can rate Brindled Tortrix sightings, London ranks 7th at under 5%, level with the leaders once rounded. The best odds are in Warsaw (Poland, under 5%), Vienna (Austria, under 5%) and Nizhny Novgorod (Russia, under 5%).
Same family: Tortricidae
The closest relatives of the Brindled Tortrix that you can see in London (family Tortricidae, Tortricid Leafroller Moths) are Light Brown Apple Moth (about 20%), Common Marble (about 10%) and Clepsis dumicolana (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Brindled Tortrix is recorded against all the insects logged in London (11 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.
