|scientific name Dioryctria okanaganella |
Dry, open forest dominated by Pinus ponderosa.
Adults fly late June - early July.
Forewings with strongly raised scales in basal, subbasal and medial area, as well as the discocellular spot. Forewings primarily black and white, with extensive red scaling throughout the wing, particularly in the basal and terminal areas. Male genitalia: Uncus constricted at the base. Valve with apical projection well-developed with hooked tip, lacking an accessory spine. Vesica with a large cornutus and many small cornutii. D. ponderosae similar in appearance to D. okanagenella, though with less strongly raised scales and less extensive reddish scaling.
Larvae bore in previous Dioryctria feeding sites in cambium under bark or in twigs. Feeding sites are recognized by fresh pitch tubes on old pitch masses.
Not of concern.
Larvae reared from Pinus ponderosa.
