Are there black flies in june?

[latebuyer]

someone mentioned there are black flies in the maritimes in june. Is that correct? How bad is it?

Here in southern Maine, black flies are typically supplanted by mosquitos by June, but the Maritimes are typically a little behind us, being farther north, so it's possible.  Severity depends on how wet a spring there was, and whether there is a breeze on the day of your visit.
