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.

life history
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.

diet info
Larvae have been collected from P. ponderosa and P. contorta.
