Saunder’s Case Moth Cocoon

This cocoon was on a post at the start of the Little Blue Gum Creek walk. It’s large, about 15cm long, with sticks woven into the sides. I remember seeing many like this when I was growing up but had never known what animal made them.

A quick search pointed to it being a Saunder’s Case Moth cocoon. During their caterpillar phase case moths make their cocoons out of silk, most species attach sticks, leaves or other debree as camouflage. Each species had a distinct type of cocoon, but they are also constrained by available materials so even within a single species cases can vary in materials and appearance.
