|scientific name Dioryctria cambiicola |
common name Western Pine Moth
Dry, open forest dominated by Pinus ponderosa or Pinus contorta.
Adults fly from late July - late August
Forewings with strongly raised scales in the basal, subbasal and medial areas, as well as the discocellular spot. Forewings predominantly reddish-brown, particularly in the costal and medial areas. Hindwings distinctively dusky brown. Male genitalia: Uncus constricted at base with lateral margins expanded. Valve with prominent hooked apical projection and prominent accessory spine. Vesica with large cornutus and many smaller cornutii. D. contortella and D. tumicolella occur with D. cambiicola, but lack the characteristic dark hindwing.
Larvae bore in cambium under bark and occasionally in twigs, buds and at the base of cones. Association with blister rust cankers on trees is also seen. Feeding sites are identified by large pitch masses mixed with frass at the gallery entrance (Mutuura et al 1969).
Not of concern.
Larvae have been collected from P. ponderosa and P. contorta.
British Columbia and Alberta south to California and New Mexico.
