Fossilised mind control, 48 million years ago

This carpenter ant (Camponotus leonardi) is caught in the throes of a fungus-induced death grip. It has clamped itself to a leaf 25 centimetres above a forest floor in Thailand, and died.

It turns out this parasitic mind-control is at least 48 million years old. David Hughes of Harvard University and colleagues discovered fossilised leaves of this age in Messel, Germany that bore characteristic “death grip” scars, suggesting that ants once clamped themselves onto them.
