Beowulf

stinging insect of the genus Apis, living in societies under a queen and producing wax and honey, Old English beo "bee," from Proto-Germanic *bion (source also of Old Norse by, Old High German bia, Middle Dutch bie), from PIE root *bhei- "bee."

Used metaphorically for "busy worker" since 1530s. The sense of "meeting of neighbors to unite their labor for the benefit of one of their number" is by 1769, American English, probably is from comparison to the combined labor and social activity of the insect: Raising-bee (1814) for building construction; quilting bee (1824, see quilt (v.)); logging-bee for a log-rolling; paring-bee for preparing harvested apples; also hanging bee "a lynching"). It was extended to other situations (such as spelling bee, attested by 1809).

To have a bee in (one's) bonnet (1825), of one who is harebrained or has an intense new notion or fancy, is said in Jamieson to be Scottish, perhaps from earlier expressions such as head full of bees (1510s), denoting mad mental activity.

Old English wulf "wolf, wolfish person, devil," from Proto-Germanic *wulfaz (source also of Old Saxon wulf, Old Norse ulfr, Old Frisian, Dutch, Old High German, German wolf, Gothic wulfs), from PIE root *wlkwo- "wolf" (source also of Sanskrit vrkas, Avestan vehrka-; Albanian ul'k; Old Church Slavonic vluku; Russian volcica; Lithuanian vilkas "wolf;" Old Persian Varkana- "Hyrcania," district southeast of the Caspian Sea, literally "wolf-land;" probably also Greek lykos, Latin lupus).

This manne can litle skyl ... to saue himself harmlesse from the perilous accidentes of this world, keping ye wulf from the doore (as they cal it). ["The Institution of a Gentleman," 1555]

Probably extinct in England from the end of the 15th century; in Scotland from the early 18th. Wolves as a symbol of lust are ancient, such as Roman slang lupa "whore," literally "she-wolf" (preserved in Spanish loba, Italian lupa, French louve). The equation of "wolf" and "prostitute, sexually voracious female" persisted into 12c., but by Elizabethan times wolves had become primarily symbolic of male lust. The specific use of wolf for "sexually aggressive male" first recorded 1847; wolf-whistle attested by 1945, American English, at first associated with sailors. The image of a wolf in sheep's skin is attested from c. 1400. See here for a discussion of "wolf" in Indo-European history. The wolf-spider so called for prowling and leaping on its prey rather than waiting in a web.
