Bag Worm feeding on Cassia

Description:

Probably a Saunder's Case Moth

Habitat:

Found feeding nocturnally on the Cassia leaves. Cassia are a known invasive weed in the area

Notes:

The worm had its head out when I pulled up next to it but the light made it hide. In the second image the leaf it was feeding on has been pulled into the bag. Image 3 is the flowers of the plant in case my id is incorrect http://www.toowoombarc.qld.gov.au/enviro...
