[the first adjective sense, ''clever, alert, etc,'' is of unknown origin, though it is conjectured that it may refer to the difficulty of catching a fly in midair, that it may be cognate with fledge and hence mean ''accomplished, proven, seasoned,'' and that it is a corruption of fla, a shortening of flash; the third verb sense, ''succeed, persuade, etc,'' is fr a cluster of jokes and phrases having to do with the Wright Brothers' and others' efforts to get something off the ground and make it fly; the two adjective senses involve either a survival or a revival of an early 19thcentury British underworld term of unknown origin]
Heb. zebub, (Eccl. 10:1; Isa. 7:18). This fly was so grievous a pest that the Phoenicians invoked against it the aid of their god Baal-zebub (q.v.). The prophet Isaiah (7:18) alludes to some poisonous fly which was believed to be found on the confines of Egypt, and which would be called by the Lord. Poisonous flies exist in many parts of Africa, for instance, the different kinds of tsetse. Heb. 'arob, the name given to the insects sent as a plague on the land of Egypt (Ex. 8:21-31; Ps. 78:45; 105:31). The LXX. render this by a word which means the "dog-fly," the cynomuia. The Jewish commentators regarded the Hebrew word here as connected with the word _'arab_, which means "mingled;" and they accordingly supposed the plague to consist of a mixed multitude of animals, beasts, reptiles, and insects. But there is no doubt that "the _'arab_" denotes a single definite species. Some interpreters regard it as the Blatta orientalis, the cockroach, a species of beetle. These insects "inflict very painful bites with their jaws; gnaw and destroy clothes, household furniture, leather, and articles of every kind, and either consume or render unavailable all eatables."
in animals, locomotion of either of two basic types-powered, or true, flight and gliding. Winged (true) flight is found only in insects (most orders), most birds, and bats. The evolutionary modifications necessary for true flight in warm-blooded animals include those of the forelimbs into wings; lightening and fusion of bones; shortening of the torso; enlargement of the heart and thoracic muscles; and improved vision. Similar modifications in insects have occurred through different evolutionary pathways. The advantages conferred by flight are also great: in terms of numbers of species as well as numbers of individuals, insects, birds, and bats are among the most successful animal groups
