Habitat
Coniferous forests and plantations dominated by spruce (Picea). Associated with spruce, black spruce, and Engelmann spruce across its range.
Distribution
Recorded from Alberta, Manitoba, and Saskatchewan in Canada. Distribution likely extends into adjacent northern United States based on range, though specific records are sparse.
Diet
feed internally within spruce needles, mining between the needle surfaces. Specific feeding mechanism creates characteristic hollowed needles.
Host Associations
- Picea - spruce including spruce, black spruce, and Engelmann spruce
Life Cycle

Behavior
