First of all, let's be clear: they are not insects, so the term "beneficial insects" is not valid. The first and second floors are all nonsense.
Toads and frogs are beneficial to nature.
The toad has a pair of venom glands behind its ears that secrete venom. In traditional Chinese medicine, the so-called "toad crisp" is prepared after the toad venom is dried.
Hope it helps.

<> similarities: Both are amphibians and feed on insects. Differences:
The toad ** is rough, ugly, has a lot of bumps on its body, secretes venom, and is inedible, but has great medicinal value; Frogs are smaller than bullfrogs, have a smooth body surface, and have patterns on their backs to catch pests.
Tips: Toads are wild protected animals, and the protection of wild animals starts from itself, refuses to buy and sell wild animal products, and does not interfere with the free life of wild animals. At present, the consumption of rare and endangered wild animals in society is not only a bad social habit, but also one of the reasons for the repeated prohibition of illegal hunting and killing of rare and endangered wild animals.
If there is no trade, there is no killing, and the consumption of wild animals is not eliminated, they do not belong on the table.
