Reg Foggerdy left a car driven by his brother late Wednesday in pursuit of a camel in the Great Victoria Desert in Western Australia state, Police Superintendent Andy Greatwood said.

After his brother alerted authorities, police trackers found the former miner sitting under a tree on Tuesday morning 15 kilometers (9 miles) from where he became lost.

“He just spent the last two days under a tree eating black ants and that sustained him,” Greatwood said. “When we found him, he was extremely dehydrated, disoriented and basically delusional.”
