Palmer-Worm

(Heb. gazam). The English word may denote either a caterpillar (as rendered by the LXX.), which wanders like a palmer or pilgrim, or which travels like pilgrims in bands (Joel 1:4; 2:25), the wingless locusts, or the migratory locust in its larva state.

גום, Joel i, 4; Amos iv, 9. Bochart says that it is a kind of locust, furnished with very sharp teeth, with which it gnaws off grass, corn, leaves of trees, and even their bark.
