The species is active mainly at night.
In the wild they can be found hiding under rocks or bark, but may reach human-occupied areas during migrations.
When the spider feels threatened, it lifts its front torso, swinging its feet to expose a red stain on its mouth and claws.
If the threat continues the spider will turn and look for a place to hide.
C. olivaceum has been reported as living in large colonies and this has been observed in the burial caves around Jerusalem and reported from dried up wells in the Jordan Valley.
