Definition
Meaning
A species of mayfly (Rhithrogena germanica, or sometimes other species) common in March, important as a fishing fly.
Primarily refers to the natural insect or the artificial fly used by anglers to imitate it. By extension, can refer to the period of March when this hatch occurs. It is a specific term in the jargon of fly fishing.

Common Pitfalls
Translation Traps (for Russian speakers)
- Do not translate as "марширующий коричневый". It is a fixed name for an insect. A descriptive translation like "мартовская поденка" (March mayfly) or transliteration "марч-браун" (in fishing context) is appropriate.
Common Mistakes
- Using it as a verb (e.g., 'The fish march browned to the surface').
- Capitalising it as a proper noun (it is generally not capitalised).
- Confusing it with a colour description (e.g., 'a march brown jacket').

FAQ
Frequently Asked Questions
No, it is not a standard colour name in English. It is the specific name of an insect, though it originates from the insect's colour and month of appearance.
Only attributively in very niche contexts related to fishing (e.g., 'a March Brown imitation'). It is not a general-purpose adjective.
Typically not. While 'March' is capitalised as a month, the compound term is usually written in lowercase unless starting a sentence, similar to other common names of insects.
No. It is highly specialised jargon. Even many native English speakers who do not fish will have never heard the term.
