The entomologist and ecologist’s first encounter with the Gympie-Gympie stinging tree produced a sneezing fit and left her eyes and nose running for hours. Even protective particle masks and welding gloves could not spare her several subsequent stings – one requiring hospitalisation – but that was nothing compared with the severe allergy she developed. “Being stung is the worst kind of pain you can imagine - like being burnt with hot acid and electrocuted at the same time,” said Marina, who at the time was a postgraduate student at James Cook University investigating the herbivores that eat stinging trees. “The allergic reaction developed over time, causing extreme itching and huge hives that eventually required steroid treatment.
