The Triplaria tree (Triplaris spp) and Pseudomyrmex ants: A symbiotic relationship with risks of attack for humans

Abstract

The authors report a massive attack by Pseudomyrmex ants on a human who touched a Triplaria - novice tree (Triplaris spp). The ants naturally live in these trees and their stings cause intense pain and discrete to moderate local inflammation. The problem is common in some Brazilian regions and can be prevented by identifying the trees.
