I was given a simple formula for rough idea of bees in colony by counting returning or leaving bees then multiplying by a number, what number escapes me, any ideas?

Thanks for that, had one that was very simple but will get the calculator out if needed, by the amount of 🐝 Traffic I'd say there are loads! There seems to be great activity mid afternoon at the moment, is this maybe signs of imminent swarming?

Mid afternoon is usually the warmest part of the day and therefore a prime time for orientation flights for young bees, so it's quite normal at this time of year for there to be a significant increase in traffic then.

Are you seeing any drones yet. They will not swarm before they produce drones. Again, mid afternoon is drone play time, so take a good look at those bees buzzing around the entrance to see if some of them are big, fat, hairy a**ed males.

There is a lot of Oil Seed Rape in flower throughout the country now, so that is triggering a rapid build up in many colonies and you may well hear them fanning to ripen honey if you go out after dark and listen to the hive. 3 of my hives have found the rape so far, but it is just coming into bloom here, so plenty time yet for the others to catch on.

Best wishes

Lots of info there thanks, though I saw a dead drone the other day and have kept looking but not seen any. Going out to listen to them now but there was a distinct sweet smell oh honey late afternoon, bees are returning with mostly yellow pollen and the odd orange 'leggings'. Not much oil seed rape too close but lots of trees, cherry, horse chestnut, apples and sycamore coming out now so would think tree pollen is on the menu. Very interesting observing at the moment.

Conserving wild bees

Research suggests that bumble bee boxes have a very low success rate in actually attracting bees into them. We find that if you create an environment where first of all you can attract mice inside, such as a pile of stones, a drystone wall, paving slabs with intentionally made cavities underneath, this will increase the success rate.

Most bumble bee species need a dry space about the size a football, with a narrow entrance tunnel approximately 2cm in diameter and 20 cm long. Most species nest underground along the base of a linear feature such as a hedge or wall. Sites need to be sheltered and out of direct sunlight.

There is a spectacular display of wild bee hotels here
