Case Moths are the hermit crabs of the insect world.  The caterpillars protect themselves by spinning a silk bag (most caterpillars can make silk) and attaching small twigs to the outside for camouflage.  And they never leave the bag.  They move around and feed by pushing their head and legs just beyond an opening at the top of the bag and retract into the bag when danger threatens.  This part of the life cycle may last for many months and sometimes years.

When the adults finally emerge from the case they don't look very much like 'normal' moths.  The males have small,  narrow, shiny and distinctly un-moth-like wings and the females don't have wings at all.
