Etymology: Chrysops is the scientific name for the deerflies and horseflies of the genus, and it is built entirely from Ancient Greek. The first element, "chrusos" (gold), gives the name its meaning, while "ops" (eye, or face) comes from the same root as "ōps," the word for the eye in Greek poetry. Taken together, the name means "golden-eyed," a reference to the bright, often striking markings on the compound eyes of many species. Because the name was assembled from classical parts, it was coined by taxonomists rather than inherited from ancient writers. Modern entomologists began naming insects in this Latinized Greek style in the 18th and 19th centuries, when the genus was described and placed in the family Tabanidae. The Greek roots were chosen for their descriptive value, so the name tells you something about the insect before you have seen one.

Synonyms: deer fly, biting fly, horsefly, tabanid, gadfly
