Examples
A bagworm begins to build its case as soon as it hatches.
Adult females of many bagworm species have only vestigial wings, legs, and mouthparts.
Case-bearer cases are usually much smaller, flimsier, and consist mainly of silk, while bagworm "bags" resemble caddisfly cases in their outward appearance a mass of (mainly) plant detritus spun together with silk on the inside.
The bagworm has a voracious appetite and is considered a serious pest.
Each bagworm generation lives just long enough as adults to mate and reproduce in their annual cycle.
Since bagworm cases are composed of silk and the materials from their habitat, they are naturally camouflaged from predators.
