This mitzvah prohibits eating all flying insects that creep and swarm, except for the specific locust species that the Torah explicitly permits (see Mitzvah 179). The prohibition includes a wide variety of insects such as flies, mosquitoes, wasps, and other similar creatures. These species are deemed a sheketz (abomination), emphasizing Israel’s calling to avoid impurity and maintain spiritual elevation even in matters of diet.

Commentary & Classical Explanation:

• Rambam (Hilchot Ma’achalot Asurot 2:20): Clarifies that most flying insects are forbidden, with the exception of those kosher locusts identified by tradition.
• Sefer HaChinuch (Mitzvah 160): The root is to instill discipline and holiness by refraining from eating creatures associated with decay and impurity.
• Talmud (Chullin 65a): Explains the distinction between the forbidden swarming insects and the few locust species that are permitted.
