Species of fly
Stonemyia tranquilla, the peaceful stonian horsefly, is a species of fly in the family Tabanidae.[2][3] The fly is about 1.5cm long and, unlike most other tabanid flies, does not need to suck blood to reproduce, hence the scientific name which translates to "tranquil".[4]
Distribution
This fly inhabits the United States and Canada, being most common in New England, New York, the St. Lawrence River Valley, Nova Scotia and New Brunswick, but is occasionally seen in the Midwest and the Appalachian Mountains southwards to North Carolina.[5]
