Hawaii has over 200 endemic Mecyclothorax species, making it one of the largest island beetle radiations.
Rice Water Weevil
A small, grey-brown weevil that feeds on rice roots as a larva and on rice leaves as an adult. Adults create distinctive narrow feeding scars along the surface of rice leaves parallel to the leaf veins.
