Abstract | Full Text

Outdoor decaying corpses immediately attract Calliphoridae and Sarcophagidae flies. However, the invasive red and black imported fire ant (Solenopsis invicta and richteri) is also attracted to carrion with a reportedly predatory behavior. We documented outdoor decomposition in piglets exposed and unexposed to fire ants. We observed early and extensive fire ant colonization with an intense necrophagous behavior. The ant-inflicted post-mortem skin lesions and flesh removal areas became blow fly oviposition sites. This work documents a previously unreported vigorous fire ant necrophagous behavior on carrion that creates wounds unrelated to the cause of death which could potentially affect post-mortem interval estimates.
