申命記 14:19

שרץ העוף — These are the lowly creatures which move upon the ground: flies, hornets and the unclean species of grass-hoppers (cf. Rashi on Leviticus 11:20), come under the term of שרץ.

וְכֹל֙ שֶׁ֣רֶץ הָע֔וֹף טָמֵ֥א ה֖וּא לָכֶ֑ם לֹ֖א יֵאָכֵֽלוּ׃

And every creeping thing that flies is unclean to you: they shall not be eaten.
