My bees are "local" (blackish) to Fermanagh and possibly related to local Irish Midland bees (where historically I think Carniolan bees were common). If swarming does occur it happens late in the season (once in early September but normally in August). I do not seem to be troubled with early season swarming (late June-July). My query (as a beekeeper of 6-7 years) is whether late swarming is a feature of bee "type" (ie., genetics) or bee management (eg., slow build-up in the Spring/early Summer) .
