(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.
Chætochilus pometellus, (Harris), is commonly called the palmer-worm.
The first is in Joel i. 4: "That which the palmer-worm hath left, hath the locust eaten."
The Jewish Bible retains the reading of palmer-worm, but affixes the mark of doubt, as it does to the canker-worm.
