The wingspan is 9–11 mm. The forewings are brown slightly reddish-tinged, towards base and apex whitish-sprinkled; a somewhat curved white fascia before middle, preceded by a darker fascia ; indistinct whitish tornal and opposite costal spots; 5 and 10 absent. Hindwings are grey. The larva is pale brown, greener dorsally ; head and plate of 2 black[3]

Adults are on wing from March[1] or April[4] to September[1] or October.[4]

The larvae feed on Abies alba,[1] Pinus mugo,[1] Pinus nigra and Pinus sylvestris.[1] They mine the needles of their host plant. The mine starts at the tip and descends, full depth, towards the base of the needle. The mine is completely filled with granular frass. Pupation takes place outside of the mine[5] in a cocoon on the ground.[6] Larvae can be found from December to March or April.
