This morning I encountered what looked like caterpillar poo that could walk. I fired off a few shots and a quick video then came home to do some research.

Leaf beetles of the genus Neochlamisus are sometimes known as the warty leaf beetles. They are members of the case-bearing leaf beetle group, the Camptosomata. Measuring 3–4 millimeters in length as adults, they are cryptic, superficially resembling caterpillar frass.
