As for her body, the head is very delicately attached to the neck and so is easily moved, not fixed like the head of a grasshopper. The eyes are prominent, and have much the quality of horn, The breast is solid, and the legs grow right out of the waist, which is not at all pinched* up, as in wasps. As in them, the abdomen is armoured and resembles a corselet in having flat zones and scales. She differs, however, from the wasp and the bee, in that her weapon is not the hinder-part, but the mouth, or rather the proboscis; for, like the elephant, she has a trunk with which she forages, seizing things and holding them tenaciously, since it is like a tentacle at the end. A tooth protrudes from it with which the fly inflicts bites in order to drink the blood, for although she drinks milk, she likes blood also. The bite causes no great pain. Though she has six feet, she walks with only four and uses the two in fwont for all the purposes of hands. You can see her standing on four legs, holding up something to eat in her hands just as we human beings do.

The fly is not born in the form which I have described, but as a maggot from the dead bodies of men or animals. Then, little by little, she puts out legs, grows her wings, changes from a creeping to a flying thing, is impregnated and becomes mother to a little maggot which is to-morrow’s fly. Living in the society of man, on the same. food and at the same table, she eats everything except oil: to taste this is death to her. Being the creature of a day— for life is meted out to her in very scant measure— she likes sunshine best and goes about her affairs in it. At night she keeps quiet and does not fly or sing, but hides away and is still.
