These are semitree- and tree-dwelling tarantulas. They are fairly aggressive by nature and quick moving. They do not have urticating (stinging) hairs, but their venom is highly powerful.
They assume a defensive stance when they feel threatened. They rise up, displaying the underside of the first pair of legs and open their chelicerae, ready to attack. In this species, the underside of the first two pairs of legs is yellow, while the remainder of the underside is black. This is intended to warn off potential attackers.
As among most tarantulas, females take their egg cocoons with them wherever they go.
