Bagworm moths are common pests of ornamental trees.  The caterpillar lives in a "bag" of sticks and leaves of the host plant, a bag which also serves as the cocoon.   Here, a caterpillar reaches out of the bag as it maneuvers along the building wall.

Here is a bagworm moth cocoon.  Although these are called Evergreen Bagworm Moths, and they can be pests of evergreens such as cedars, they are also common on deciduous shrubs as shown here.  These bags are very often seen on trees and bushes at Fermilab. 

The female bagworm moth does not fly.  The female lays eggs in the cocoon in the autumn after mating, and the eggs overwinter.
