noun
Refers to the species Oxya yezoensis or similar grasshoppers found in rice paddies.

蝗 is a general term for grasshoppers, especially those that swarm; 羽長蝗 specifies a particular species with long wings.
Compound of 羽 (hane, 'wing'), 長 (naga, 'long'), and 蝗 (inago, 'grasshopper'). The exact derivation is uncertain, but the name describes the insect's long-winged appearance.
