Classification
Diagnostic Features of Larvae
- Larva. No genal bristles; ocellus prominent; last joint of maxillary palpi nearly twice length of second, slightly larger than last labial, basal joints transverse; second joint of antennae slightly longer than first, latter as thick as long; anterior edge of hypostoma thick; prothorax bearing four conspicuous dark ochraceous tergal plates; pronotum posteriorly with slightly oblique, sharply impressed striae, median suture impressed; ampullae alutaceously subtuberculate, with a deep median furrow; pleural discs distinct on second and third segments, fainter on first and fourth; legs three-jointed. Adapted from Craighead (1923).
Biology and Economic Importance
- This species has been collected in dead grapevines (Vitis). The larval mines are extended principally through the wood and are tightly packed with frass. Pupation takes place very early in the spring. Adapted from Craighead (1923).
