The wingspan is 13–19 mm. Adults are on wing from May or June to the end of July. There is one generation per year.
The larvae (caterpillars) feed on European Silver Fir (Abies alba), Norway Spruce (Picea abies), junipers (Juniperus) and pines (Pinus). Larvae can be found in resin deposits, thickened cankerous branches infested by fungi and in mechanical injuries of the host plant. The larvae only mine to the nearest injury on the bark.

In addition, the specific name interruptana was used in a list ot tortrix moths by G.A.W. Herrich-Schäffer in 1848 already. But he did not provide a description then, thus the scientific name – later determined to refer to the same species as J.W. Zetterstedt's Grapholitha duplicana – was validly established by him only in 1851.
