Syagrus (beetle)
Syagrus is a genus of leaf beetles in the subfamily Eumolpinae.[4] They are known from the mainland of Africa as well as Madagascar. They are often attracted by plants in the family Malvaceae;[5] Syagrus rugifrons and Syagrus calcaratus are pests of cotton. The larvae of Syagrus calcaratus attack the roots of the plant and cause it to wilt.[6]
