Cankerworm in the Bible

Joel 1:4 That which the palmerworm hath left hath the locust eaten; and that which the locust hath left hath the cankerworm eaten; and that which the cankerworm hath left hath the caterpiller eaten.
Joel 2:25 And I will restore to you the years that the locust hath eaten, the cankerworm, and the caterpiller, and the palmerworm, my great army which I sent among you.
Nahum 3:15-16 There shall the fire devour thee; the sword shall cut thee off, it shall eat thee up like the cankerworm: make thyself many as the cankerworm, make thyself many as the locusts. 16 Thou hast multiplied thy merchants above the stars of heaven: the cankerworm spoileth, and flieth away.
