Charles Ellicott Commentary Psalms 78:46

"He gave also their increase unto the caterpillar, And their labor unto the locust." — Psalms 78:46 (ASV)

Caterpillar. —Hebrew, chasîl. (See 1 Kings 8:37.) Probably the locust in the larva or pupa state. For locust see Exodus 10:4 and following, and Bib. Ed., iv. 292. The Septuagint, Vulgate, and Symmachus have “blight,” but in 2 Chronicles 6:28 “cockchafer,” as Aquila and Jerome here.
