Kalium,
It is hard to tell from your description. Swarming is unlikely this time of year even for your area.
They are unlikely to swarm to the base of the hive they left.
Good to know. I thought that they will swarm to nearby objects (like a post a metre away or so), but yeah, wasn't really sure.
I often get small swarms turn up to my apiary this time of year. They are just a handful of bees with a queen and they are a pain in the arse.
That's fascinating. Yeah it was just a couple of handful of bees with a queen by the looks.
Judging by the clustering behaviour that I saw in the new box, I definitely got the queen.
There were so many bees in the air, nothing I've seen around my hive before (and
there was no robbing going on).
Why do they show up at your apiary? Are they hoping someone will let them in?
I've never heard of this in anything I've ever read (swarms turning up at existing apiaries/hives)
I think they come out of feral hives in the area. I spray them with soapy water and kill them.
I know of a couple of reasonable size (one 40+ hive, another 160+ hive) apiaries within a few kms as well.
Given that I'm keen to expand my hive numbers, I'd much rather try and see if I can make a hive
out of those bees wherever they came from :)
Have a look at the "swarm" tomorrow & let us know what you see.
You need to build up to more than one hive in the spring. Two or three hives means you don't have to worry about those little surprises.

TBH I was hoping I could grow my hive numbers by swarm trapping + splitting in the spring.
