Confidence:Low
Confidence Notes:I am unsure as to why this is CDFA A-rated. There is no natural habitat of its preferred hosts. It may behave very differently in CA than the eastern US (ie. feed on pine) which would affect these ratings.

Spread Rate
Mostly nursery stock and home garden. Habitat in CA sparse, so spread and establishment should be slow. Can fly or be transported in infested plant material.
3
Spread Amount
Balsam fir, white spruce, red spruce, and black spruce are highly preferred. It is unlikely that this pest will become highly established, though it may begin to feed heavily on other conifers.

Damage
Notes

Ecological
It is unlikely that this pest will become a serious pest due to the lack of hosts. However, it has attacked other conifers (minimally) ie. Tamarack, pine and hemlock.

Detection may be achieved through pheromone trapping.
