Classification
Diagnostic Features of Larvae
- Larva. Form slender; integument smooth, shining, clothed with fine, long, whitish hairs; labrum transversely oval; anterior margin of head finely granulate; pronotum about as wide as long, asperities finer, extending over three-fourths the length; eusternum bearing a single row of asperities, and sternellum a few on median area; ampullae finely and rather sparsely asperate; pleural tubercles bearing two long slender setae; spiracles oval, peritreme strongly chitinized. Pupa. Form as in adult; no chitinous points on thoracic segments and but few on abdominal ones; setae fine and slender. Adapted from Craighead (1923).
Biology and Economic Importance
- The larva of this species causes a gall from 1.5 to 2 inches in diameter on the young stems of Populus and Salix. The larva mines under the bark and into the wood, completing its burrow by a short, straight gallery in the wood parallel to the stem. Pupation occurs at the top of this chamber. Adapted from Craighead (1923).
