Question of the Week: Bagworm

Last week the question was:  What is this?


This is a bagworm.  Bagworms are a relatively minor pest of mostly evergreen trees and shrubs.  It is a caterpillar that builds a protective bag around it as it develops.  Eggs are laid inside the bag and when they hatch, they leave the bag to forage and construct their own bag.  The bag is made of silk along with materials from the plant on which they are feeding.  When males are mature, they leave the bag and fly to mate with the females in their bags.  The female then lays eggs within her pupal case and dies shortly after.  For more info, take a look at this publication.


Here is this week’s question:  What will this be when it grows up?
