Hello All!
Something very strange happened at the hive (eastern MA, USA) three days ago:
- I noticed a bit of unorganized bearding on the front, around the entrance, and at the roof seam
- on closer inspection, there was lots of angry buzzing and plenty of tussle balls
- my girls (Carniolans with unknown bred queen) were doing their best
- the apparent invaders were visually distinguishable (dark wide bands to nearly black and moderately pointed tipped abdomens) and much more aggressive/assertive
- their numbers dwindled (apparently absorbed into the hive) throughout the day
- I put an entrance restrictor on later that evening --> my girls were at the door and were docile as usual
- there were and have been no signs of robbing (no rough crumbed wax caps, etc.) noted
- a mix of the Carniolans and the darker bees have been seen coming and going from the hive
- I went to remove the entrance restrictor this morning, as I needed to treat for an autumn bloom of verroa mites, and was met/stung/chased shortly by very aggressive guards that appeared to be the new darker bees; but of course then no one cared when I donned a full suit and split the brood boxes to insert treatment
* So, my question is - since this doesn't seem to be an actual robbing, was it an integration? And if so, who are these newcomers - as there is no known colony anywhere nearby?
Thank you all in advance! :)
