The headword is a masculine noun in the nominative (and vocative) singular. It has three meanings according to LSJ s.v.: (1) a species of biting fly, probably from the genus Tabanus, that pesters livestock; (2) a spur; and (3) metaphorically, an incentive; cf. Chantraine s.v. (1).
[1] The first gloss is a masculine noun in the nominative singular; see LSJ s.v., which tentatively identifies it as Tabanus bovinus. Also see the scholia to Homer, Odyssey 22.299 (web address 1); Hesychius mu2017; Etymologicum Gudianum s.v.; omicroniota 180; and omicroniota 181. The mu/wy is distinguished from the oi)=stros at Aristotle, History of Animals 490a20 and 596b14. [In her critical apparatus, Adler notes that mss AGF omit this gloss and that ms M inserts it above the passage.]
[2] Same glossing of the headword in Photius' Lexicon (mu641 Theodoridis), Hesychius mu2017, and the Synagoge; cf. Lexica Segueriana 305.16, ps.-Zonaras 1380.3, and Etymologicum Magnum 596.21 (Kallierges). Adler also cites Etymologicum Genuinum.
[3] A garbling of a phrase in Callimachus, Hecale fr. 301 Pfeiffer (accusative case there), with comment from the scholia there.
[4] Polybius fr. 61 Büttner-Wobst. An example of the headword's sense as a spur also occurs at Polybius 11.18.4 (web address 2): prosqe/nta tou\s mu/wpas (having applied the spurs). [Adler notes that mss GM preferred the genitive plural a)mfote/rwn tw=n merw=n (from either of the sides) for the Suda's dual number; cf. Büttner-Wobst, p. 523.]
[5] Epithet of the goddess Aphrodite, born in the east, and traditionally linked to the island of Cyprus, where her most prominent cults were located; see OCD(4) s.v. Aphrodite, kappa 2738, and alpha 974 (end).
[6] Greek Anthology 5.203.1-2 (Asclepiades), the hetaera Lysidice dedicates a golden spur to Aphrodite; cf. Gow and Page (Hellenistic Epigrams, vol. I, 45-46), (Hellenistic Epigrams, vol. II, 120-1), and another extract from this epigram at upsilon 659. As Gow and Page note (ibid.), by way of its references to equestrian practice the epigram plays on allusions to Lysidice's professional techniques. [This and the next two excerpts from the Greek Anthology were omitted by ms. F (so Adler).]
[7] Greek Anthology 6.95.1, Antiphilus' epigram to the plowman Parmis (Gow and Page, The Garland of Philip, vol. I, pp. 100-1; vol. II, pp. 126-7). Cf. pi 1842.
[8] Greek Anthology 6.233.5 (Maikios/Maecius/Maccius), the horseman Stratius's dedication of equestrian equipment to Poseidon; cf. Gow and Page (Garland of Philip, vol. I, 282-283 and vol. II, 314-6), and further excerpts from this epigram at gamma 373, kappa 1520, mu 266, and psi 66.
