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.

GBIF citizen-science records
It is estimated from how often the Brindled Tortrix is recorded against all the insects logged in Nizhny Novgorod (6 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.
