The larvæ of this insect, says Mr. Clark, are mostly known among the country people by the name of wormals, wormuls, warbles, or, more properly, Bots. And our ancestors erroneously imagined that poverty or improper food engendered them in horses. The truth, however, seems to be, that when the animal is kept without food the Bots are also, and are then, without doubt, most troublesome; whence it was very naturally supposed that poverty or bad food was the parent of them.[1013]
A cow with its hide perforated by Warbles, in England, was said to be elf-shot: the holes being made by the arrows of the little malignant fairies. In the Northern Antiquities, p. 404, we find the following:
“If at such a time you were to look through an elf-bore in wood, where a thorter knot has been taken out, or through the hole made by an elf-arrow (which has probably been made by a Warble) in the skin of a beast that has been elf-shot, you may see the elf-bull naiging (butting) with the strongest bull or ox in the herd; but you will never see with that eye again.”
In the Scottish history of the trials of witches, we find the following: Alexander Smaill offended Jonet Cock, who threatened him, “deare sail yow rewe it! and within half ane howre therafter, going to the pleugh,—befoir he had gone one about, their came ane great Wasp or Bee, so that the foir horses did runne away with the pleugh, and wer liklie to have killed themselves, and the said Alexander and the boy that was with him, narrowlie escaped with their lyves.”[1014] Possibly the incident is not exaggerated, as a single Œstrus will turn the oxen of a whole herd, and render them furious.
Spencer, in his Travels in Circassia, speaks of a poisonous Fly, known in Hungary under the name of the Golubaeser-fly, which is singularly destructive to cattle. The Hungarian peasants, to account for the severity of the bite
of this insect, tell us that in the caverns, near the Castle of Golubaes, the renowned champion, St. George, killed the dragon, and that its decomposed remains have continued to generate these insects down to the present day. So firmly did they believe this, that they closed up the mouths of the caverns with stone walls.[1015]
