Leaf beetle, grass leaf beetle (not an accepted common name).
Oulema species. The Oulema species recorded from Fiji has not been identified. However, the cereal leaf beetle (oat leaf beetle), Oulema melanopus, is a major pest of wheat, barley, oat, and millet, worldwide. In countries where it is not yet present, it is considered a pest of quarantine importance. For these reasons, the Fiji species is described here.
