Heppner (2003) reported February to April, July to October. (2)

The larval host plants include: (2)

Larix occidentalis (western larch) Pinaceae.

Pseudotsuga [taxifolia] menziesii (Douglas fir) Pinaceae.

Possibly more than one species involved. The type locality is Evaro, MT. It's range extends to the Northwest. The host plants are Larix occidentalis and Pseudotsuga taxifolia(5) both of which are absent in much of the reported eastern range. Eastern specimens are currently interpreted as laricana based on genitalic illustrations in Heinrich.

Cydia candana has the white costal markings more evenly distributed, not paired, giving the coastal margin a whitish appearance. In laricana the markings are paired and often fused, one pair at the start of the median fascia (anti-median), which is not always present, followed by four more.
