Cankerworm

Hebrew: yelek

“the licking locust,” which licks up the grass of the field; probably the locust at a certain stage of its growth, just as it emerges from the caterpillar state (Joel 1:4; 2:25)

The word is rendered “caterpillar” in Psalm 105:34; Jeremiah 51:14, 17 (but Revised King James Version “canker-worm”). “It spoileth and fleeth away” (Nahum 3:16), or as some read the passage, “The cankerworm putteth off [i.e., the envelope of its wings], and fleeth away.”
