Bug was the moniker given to a human female originating from the planetoid Sídi; she was the offspring of Rank and Leera, who operated an inn. Her parents typically disregarded and underestimated her, and she received the nickname Bug early in life, in reference to the native Sídi ash-beetles. This occurred after Leera crushed one that Bug had tried to domesticate. Eventually, Bug lost recollection of her original given name. In approximately 20 BBY, Bug encountered Falta, a Dathomirian sorceress who journeyed to Sídi in search of information regarding her missing daughter, Yenna. Bug successfully impressed Falta and aided her in discovering a transmission, intercepted by a abandoned military relay tower, indicating her daughter's location in the Mid Rim. Subsequently, Bug convinced Falta to permit her to accompany her, intending to eventually select a new, more suitable name for herself.
