The wingspan is 12–18 mm. The forewings are ferruginous ochreous, blackish-mixed in disc posteriorly. The base and costal fold in the male are dark brown. There is a ferruginous-brown oblique mark from dorsum near the base.

The hindwings are blackish-grey, in female lighter anteriorly. The larva is greenish-yellowish, with a head and plate of 2 green or light brown.

With luck
About 10% of wildlife watchers report a Red-Barred Tortrix sighting in Liverpool on a given day, based on 27 verified sightings from GBIF citizen-science data. It is the 233rd most-seen of the 632 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
June and July
In those months about 20% of wildlife watchers report a Red-Barred Tortrix in Liverpool on a given day, against under 5% in September and November–April, the lowest months.

GBIF citizen-science records
It is estimated from how often the Red-Barred Tortrix is recorded against all the insects logged in Liverpool (27 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.
