Flattened Bark Spider

Hemicloea rogenhoferi

The Flattened Bark Spider is a fascinating native spider that is a master of camouflage and concealment. As its name suggests, its body is extraordinarily flat, allowing it to live in the narrow spaces under the peeling bark of trees, particularly eucalypts. It is a nocturnal hunter that does not build a web to catch prey. Due to its cryptic lifestyle and specific habitat, it is rarely seen by people and is not a household pest. It is a harmless component of the Australian forest ecosystem, preying on insects and other arthropods that share its under-bark habitat.
