|scientific name Dioryctria vancouverella |
Pine forest along Pacific coast
Adult fly July - early August
Forewings with strongly raised scales in basal area, subbasal area, medial area and discocellular spot. Primarily black and white with brownish-red scales in the basal, subbasal, medial and terminal areas. Male genitalia: Uncus unconstricted and apically rounded. Valve with prominent apical projection and accessory spine. Small teeth present along the costal edge at the base of the apical projection. Vesica with large cornutus and many smaller cornutii. Female genitalia: Ductus bursa heavily sclerotized, equal width along entire length and convered with minute spicules. D. vancouverella morphologically similar to D. pentictonella. Degree of reddish scaling and contrast in transverse bands are cited as distinguishing characters (Mutuura et al 1969), though a great deal of variation exists making morphological identification nearly impossible.
Larvae feed primarily in buds of host plant, though may possibly feed on shoots as well (Mutuura et al 1969).
Shore pine (Pinus contorta var. contorta) is the primary host, though has been recorded on introduced P. mugho, P. nigra and P. radiata.
Southern British Columbia. Based on type series collected around Vancouver.
