A recent study led by Yoram Zvik, Dr. Sharon Warburg and Dr. Efrat Gavish-Regev from the National Natural History Collections at The Hebrew University of Jerusalem documented the first observation of phoresy involving a myrmecophile pseudoscorpion on a myrmecophile scorpion.
Halfway through the ride, the scorpion and the tiny pseudoscorpion both sting each other. Each one asks the other, "but why have you stung me?"
"It's just my nature," they both respond before dying.
