Parelaphidion aspersum

Classification Diagnostic Features of Larvae
  • Larva. Similar to Elaphidion mucronatum but readily distinguished by the greater degree of hairiness, the hairs being very fine; head oval in cross-section, but not so markedly as in Anelaphus villosus, labrum, transversely oval, very finely ciliate; hairs about epistoma very short, much shorter than antennae while in E. mucronatum they are about as long as antennae; epistoma thickened, broadly and rather deeply curved, wrinkled. Spiracles small, nearly orbicular, some abdominal ones but little larger than ocellus. Pupa: Head, pronotum, mesonotum, and metanotum unarmed; a transverse row of acute spines on posterior border of first few abdominal segments, becoming arranged in an oval manner on posterior ones; several spines on eighth; a median longitudinal stripe of very fine pubescence on first seven. Adapted from Craighead (1923).
Biology and Economic Importance
  • The larvae here described have been found only in the outer bark of Morus, where an irregular contorted gallery is excavated, sometimes scoring the cambium. A larger, more robust form, having larger spiracles and finer body-hairs, is found beneath the bark of dead, somewhat decaying hickories. Adapted from Craighead (1923).
