Black American Gad Fly, maggot, and chrysalis, after Riley. 
Should these flies be troublesome it would seem—looking at their 
great size, which makes them very conspicuous ; and their loud hum, 
which draws attention to their presence ; and also considering their 
habit of circling round the animal before striking for blood-sucking— 
that an active boy might secure the fly with a common long-handled 
insect net when on the wing, or with finger and thumb on the animal; 
but I have mainly mentioned this attack to show how completely dif¬ 
ferent the Ox Gad Fly is in size and appearance, in condition in every 
state, and in habit, from the excessively injurious cattte pest the Ox 
Warble Fly.
