Tetropium cinnamopterum
Classification
Diagnostic Features of Larvae
- Larva. Form rather slender, cylindrical, closely clothed with fine yellowish-white pubescence. Easily recognized by the fact that the caudal spines are connate conical to apex, then suddenly bifurcate. Labrum densely hairy in front; genal bristles short, fine, dense; hypostoma deeply curved. Velvety pubescence on posterior prothorax and ampullae light, castaneous, extremely fine. Spiracles orbicular, large. Pupa: Form as in adult. Pronotum sparsely beset with chitinous-tipped papillae; mesonotum and metanotum glabrous; abdominal terga beset with a posterior band of chitinous-tipped papillae; caudal segment bearing two very slender, acute, widely separated, incurved spines. The larvae feed only in dead trees. They have been collected from Abies balsamea, Pinus, and Picea. The mines are constructed entirely under the bark until the short pupal cell is made in the outer sapwood or bark. Its range extends through the eastern and northwestern North America.
