A type of small moth larva that constructs and carries a protective case made of leaves, silk, or other materials as it feeds and develops.
Compound of 'case' (protective covering) and 'bearer' (one who carries). Named directly from the visible behavior of the larva—it literally bears or carries its case as a mobile home while eating and growing.
Casebearer moth larvae are like tiny architects—they build little protective houses out of whatever materials are around (bits of leaf, their own silk, sometimes debris) and drag them around as they munch on crops, making them both clever engineers and agricultural pests.
