Definition
Meaning
A common name for various species of biting horseflies, especially of the family Tabanidae, known for their painful bite and prevalence in warmer months.
Often refers specifically to troublesome flies in rural or marshy areas; can be used generically for large, aggressive biting flies.
Linguistics
Semantic Notes
The term is more common in specific regions (e.g., Australia, parts of the UK). It is not a precise scientific classification but a folk name applied to several similar species.
Dialectal Variation
British vs American Usage
Differences
In British English, 'march fly' might refer to specific regional horseflies. In American English, 'horsefly' or 'deer fly' is more common; 'march fly' is rarely used and would likely be understood as a regionalism.
Connotations
Both convey a nuisance insect. British: can imply a seasonal pest of marshy areas. American: if used, sounds technical or old-fashioned.
Frequency
Much more frequent in Australian and some British regional dialects. Very low frequency in general American English.

Frequently Asked Questions
No. March flies (horseflies) are larger, bite painfully to suck blood, and are common outdoors. Houseflies are smaller, do not bite, and are found around human habitation.
The name likely originates from the Old English 'marce' or similar words related to a boundary or march (marshy land), or from the month of March when they become active. It is not related to the verb 'to march'.
Yes, like many biting insects, some species of horseflies (called march flies) can mechanically transmit pathogens, though they are not as notorious as mosquitoes for disease transmission.
Clean the bite with antiseptic, apply a cold compress to reduce swelling, and avoid scratching. Monitor for signs of infection or allergic reaction.
