The whip scorpion, Mastigoproctus Giganteus (Uropygi: Thelyphonidae), preys on the chemically defended florida scrub millipede, Floridobolus Penneri (Spirobolida: Floridobolidae)

Abstract

On several occasions in Aug-Sep 2008 we detected giant whip scorpions, Mastigoproctus giganteus, feeding on rare Florida scrub millipedes, Floridobolus penneri, in bucket-style pitfall traps in the field. Subsequently in laboratory feeding trials we determined that M. giganteus will readily attack, kill, and consume F. penneri even if the prey discharges its irritating defensive secretion.
