FWL: 4.5-6.5 mm
Adults are small and brown. Many individuals have a pair of white strigulae that run continuous from costa to dorsum; expression of these markings may vary considerably. Male genitalia are characterized by a toothlike projection of the ventral margin of the valva and numerous small cornuti in the aedeagus. Female genitalia are characterized by a short ductus bursae and a pair of small signa in the corpus bursae.
Adults of Cydia coniferana are similar to other Cydia and Grapholita. A genitalic dissection may be necessary to confirm identity.
Late instar larvae are white or yellowish with a light-brown head that may have darker posterolateral shading. The prothoracic shield is yellowish brown and lightly sclerotized and the anal shield is marked with dark-brown spots.
Cydia coniferana completes 1-2 generations per year in Europe. Adults are present from mid-May to August.
Larvae create a silk-lined tunnel under the bark of the host tree and feed in the cambium. Larval damage is characterized by loose bark and exuded frass mixed with resin. Larvae often infest trees that are infected with fungus or those that are injured.
Larvae have been reported feeding on various species of fir, spruce, and pine. This species is generally characterized as an occasional pest of young pines.

Cydia coniferana is distributed from Europe east to China and Mongolia. The first North American record is from New York in the late 1950s but the population never established. It was not detected again in North America until an adult was collected in Washington in 2000. Additional surveys have shown that it is established and widespread in Washington and Oregon, although unpublished molecular data suggests that this recent introduction may be a different species.
