Sometime in the first week of May two of my bait hives were occupied by swarms. One was knee-height in a field and the other was above head-height on top of my greenhouse. I was away all week so cannot be sure the date the swarms moved in (though looking back at the weather records I suspect it was mid-week). The bees seem to be drawing out the frames well but it’s been too cold to do an inspection. This is a good example – both my absence and the lousy weather – of a situation when a box full of frames allows the bees to get established, rather than adding the frames after it’s occupied. The clear ‘crownboard’ on these Modern Beekeeping poly Nationals make it simple to take a quick peek without disturbing the colony too much.
In the larger swarm (right) the colony has divided to occupy the two frames of old tatty drawn comb I left on either side of the box. In retrospect I think only one manky old brood frame is probably needed, so when I transfer these to new boxes I’ll re-populate the bait hives with nine foundationless frames and one old frame. Despite the temperature (which has hovered between 11 and 13oC most of the last few days) there’s a reasonable flow on from remaining OSR, so I’m not feeding them. Pollen was being taken into both colonies today when I checked, suggesting there’s a mated, laying queen present.
The forecast looks to be improving for the end of the week. A lot of colonies appear to be delaying swarming because of the inclement weather. Several inspected at the weekend in the association apiary had sealed QCs but the queen still present (we couldn’t avoid the bad weather as we were running a queen rearing course and needed larvae for grafting). Therefore I’m going to empty these bait hives as soon as possible, move the captured swarms to a temporary apiary, refill the boxes with more frames, add a drop or two of lemongrass oil and put them back in position.
Finally … I’m not aware I’ve lost a swarm as my queens are all clipped (I think) so these two are likely from one of the many other beekeepers in the area. Thank you!
