Strabo Geography 13.1.64

[64] Now the story of the Teucrians and the mice—whence the epithet “Sminthian,” ¹ since “sminthi” means “mice”—must be transferred to this place. And writers excuse this giving of epithets from small creatures by such examples as the following: It is from locusts, ² they say, which the Oetaeans call “cornopes,” that Heracles is worshipped among the Oetaeans as “Cornopion,” for ridding them of locusts; and he is worshipped among the Erythraeans who live in Mimas as “Ipoctonus,” ³ because he is the destroyer of the vine-eating ips; ⁴ and in fact, they add, these are the only Erythraeans in whose country this creature is not to be found. And the Rhodians, who call erysibe ⁵ “erythibe,” have a temple of Apollo “Erythibius” in their country; and among the Aeolians in Asia a certain month is called Pornopion, since the Boeotians so call the locusts, and a sacrifice is offered to Apollo Pornopion.

[64] The story about the Teucri, and the mice from whom the name of Smintheus is derived, (for mice are called Sminthii,) must be transferred to this place. Writers defend the derivation of titles from insignificant objects by examples of this kind; as from the parnopes, which the Oetaesans call cornopes, Hercules had a surname, and was worshipped under the title of Hercules Cornopion, because he had delivered them from locusts. So the Erythraeans, who live near the river Melius, worship Hercules Ipoctonus, because he destroyed the ipes, or worms, which are destructive to vines; for this pest is found everywhere except in the country of the Erythraeans. The Rhodians have in the island a temple of Apollo Erythibius, so called from erysibe, (mildew,) and which they call erythibe. Among the Aeolians in Asia one of their months is called Pornopion, for this name the Boeotians give to parnopes, (locusts,) and a sacrifice is performed to Apollo Pornopion.
