Eucopina rescissoriana

(Heinrich, 1920)

Lodgepole Pine Coneborer Moth

A small whose bore into the cones of lodgepole pine (Pinus contorta). The reflects this specialized association. are rarely observed directly; records primarily derive from larval collections and cone dissections. The appears restricted to regions where its pine occurs.

Identification

are small with wingspans likely under 15 mm, consistent with the . Diagnostic features for Eucopina rescissoriana specifically have not been published in accessible literature. Separation from congeneric requires examination of or larval association. The provides a field clue where lodgepole pine cones are present.

Habitat

Associated with lodgepole pine (Pinus contorta) forests, particularly where cones are abundant. Specific microhabitat preferences for are undocumented.

Distribution

Western North America, corresponding to the range of lodgepole pine (Pinus contorta). iNaturalist observations cluster in the Pacific Northwest and Rocky Mountain regions.

Diet

feed within lodgepole pine cones. feeding habits are unknown.

Host Associations

  • Pinus contorta - larval Lodgepole pine cones

Life Cycle

develop inside pine cones. likely occurs within the cone or in surrounding substrate, though specific details are undocumented. timing is unknown.

Behavior

are concealed feeders, boring into cone and seeds. are presumably and may be attracted to light, though this has not been documented for this specifically.

Ecological Role

As a seed , reduce lodgepole pine seed viability. impacts on forest are likely minor given the specialized nature of the association and presence of other seed predators.

Human Relevance

Of minor economic concern; coneborers may reduce seed collection yields for reforestation programs. Not a forestry pest of major significance.
