Less-stick Case Moth larva

Trigonocyttara clandestina


The caterpillar of a case moth in a mobile silk case seen whittling the twig (pics 1 & 2), perhaps to attach it to the case later. Attached to the silk case were a few leaves and twigs. The case was about 45mm long with some of the twigs extending to about twice the length of the case. Pic 5 shows the caterpillar's legs poking out of a soft silky case.


Young Eucalyptus tree - stringy bark. Spotted beside a busy highway.


To see this case moth caterpillar in action was just amazing ! The case appeared to have very few sticks attached to it and they were of uneven length, the reason for it's common name,perhaps. Family: Psychidae Would like confirmation of this ID.

Thanks everyone. I honestly did not see any of the details at first, except that the larva was moving back and forth very slowly. I thought I should have a shot of the upper part of the sack with the legs poking out-you can imagine how excited I was when I saw the chiseled wood in the close-ups!
