  1. My mind is blown. Until now, this was one of the most impressive structures built by arthropods that I have seen:

    ...this one is equally insane though!

    1. Hi Annette. this was the only shot I got of this casemoth so the posting is really about the amazing structure.
      It's even still got my fat fingers in there !!... but thanks for the kind words. :)
      I'm sure Nicky Bay would make it look amazing.

This Caterpillar attaches sticks all around its case, all of the same length, and attaches them parallel to the axis of the case. When the Caterpillar grows sufficiently long, it attaches a new set similarly arranged to the old set, except that more are attached so that the radius of the new part of the case is bigger. The Caterpillar does this several times as it grows, giving a tiered appearance to the case. The case can grow to a length of up to 3 cms.
