Microlarinus lypriformis
Species of beetle
Microlarinus lypriformis is a weevil of the family Curculionidae.[1] It lays eggs in the stems of the puncturevine, Tribulus terrestris, and the larvae feed on the pith of the plant. After pupation, the adult emerges through holes bored in plant.[2] Along with the seed-feeding Microlarinus lareynii it has been introduced as a biological control agent in the United States of America[2] and Canada[3] against Tribulus terrestris.
