Ribbed-cocoon maker moths

Definition

A family of small moths (Lepidoptera: Bucculatricidae) whose larvae construct distinctive longitudinal-ribbed silk cocoons for pupation, often attached to host-plant stems or leaves. Adults are typically drab and small-bodied; larvae are leaf miners or skeletonizers on diverse woody and herbaceous plants.

Etymology

From the characteristic ribbed structure of the larval cocoon; 'maker' reflects the active construction behavior.

Example

The ribbed-cocoon maker moth Bucculatrix albertiella mines leaves of oak (Quercus), with its pupal cocoon bearing 8–10 pronounced longitudinal ridges visible to the unaided eye.

Synonyms

• Bucculatricidae

Related Terms

• leaf miner
• skeletonizer
• cocoon
• pupa
• Lepidoptera
• microlepidoptera
• host-plant association

Usage Notes

The common name refers specifically to the pupal cocoon morphology; not all Bucculatricidae have been examined for this trait, but it is diagnostic for the family. Previously treated as a subfamily within Lyonetiidae or placed variously in Gracillarioidea; current molecular and morphological data support family rank. Larvae of many species are economically minor pests of fruit trees and ornamentals.
