We were sipping Aperol Spritzes around dusk in Sydney, Australia. One of our group spotted an orange and black headed shard of bark moving up the tree next to us. We were fascinated by how quickly it scaled the branch; often vertically.

A Google search revealed the interloper to be the caterpillar of a Saunders’ Moth (metura elongatus), found on the Eastern seaboard.
