Warble fly is a name given to the genus Hypoderma, large flies which are parasitic on cattle and deer. Other names include "heel flies", "bomb flies", and "gad flies", while their larvae are often called "cattle grubs" or "wolves." Common species of warble fly include Hypoderma lineatum (horse), Hypoderma bovis (cattle) and Hypoderma tarandi (reindeer) .
Adult warble flies are large, hairy and bee-like; brown, orange or yellow in color. The adults have vestigial mouthparts and so do not feed during their short lifespan, which can be as little as five days.
They are found in all continents of the northern hemisphere, principally between 25 and 60 degrees latitude.

Famous quotes containing the words warble and/or fly:
“Measure your health by your sympathy with morning and spring. If there is no response in you to the awakening of nature—if the prospect of an early morning walk does not banish sleep, if the warble of the first bluebird does not thrill you—know that the morning and spring of your life are past. Thus may you feel your pulse.”
—Henry David Thoreau (1817–1862)
“As long as you don’t fly openly in the face of society, society doesn’t ask any inconvenient questions; and it makes precious short work of the cads who do. There are no secrets better kept than the secrets everybody guesses.”
—George Bernard Shaw (1856–1950)
