Contents The Beekeeping Year Inside the hive Outside the hive Swarming Discussion
Who are we talking about?? Honey Bee: Apis mellifera, migrant from Africa after the last ice age. European subspecies Irish {Northern European Black bee}: Apis Mellifera Mellifera Italian: Apis Mellifera Lingustica Carnolian: Apis Mellifera Carnica Spanish: Apis Mellifera Iberica Buckfast: hybrid of many unstable??

Inside the Hive Seasonal changes within a honey bee colony in 2 month slots January February March April May June July August September October November December
Outside the Hive There are critical plants at certain times through the year These produce either large quantities of food for bees or small quantities but at a vital time What do bees take back to the hive? Nectar Pollen Water Propolis
January - February Coldest months Bees cluster heat and preserve food Mild days cleansing flights Queen may start to lay a few eggs in centre of cluster Hive is sealed dont open Ventilation damp fosters mould and disease Beekeeper making up new equipment
January February On fine days bees emerge to forage Still have stores of honey {hopefully} but need to supplement this and start feeding newly hatched larvae - pollen Key plants: snowdrop, crocus, hazel, witchazel, willow, mahonia Low Nectar but good pollen yields Supplement with bakers fondant
The Beekeeper in Winter
March - April Colony activity increases Significant increase in population Grow from 5000 to 30000 {up to 60000} by June Food required pollen and nectar Larval food little royal jelly then bee bread 21 days from egg laid to emerging adult {3 egg, 5 larva,13 pupa} 3 weeks before adult fully mature Colonies most at risk from starvation Beekeeper clean and replace equipment
March April Bee numbers in hive are increasing Great danger of starvation 1 or 2 weeks bad weather can be disastrous Plants: willow, cherry, dandelion, early fruit bushes, gorse, hawthorn Feed with light syrup, early flow stimulates the queen to lay can be risky
May June The big flow of the year fill supers, 25lbs, of honey per week Beekeeper will collect largest part of annual honey crop Key Plants: horsechestnut Others: oil seed rape {other brassicas}, apple {and other fruit trees only cherry good nectar}, dandelion, raspberry
May - June Queen now laying 1000 to 2000 eggs per day Large quantities of nectar and pollen required Large numbers of young bees orientation flights Colony may raise new queens in special cells Swarm control a major issue Beekeeper needs to thoroughly inspect each hive weekly check for eggs and queen cells
Eggs in cells
Eggs and larvae
Worker Emerging
Honey stores on brood frame
July - August Traditional time to store excess honey No longer true climate and agriculture July dearth Nectar gathered is 80% water Honey is < 20% water Supercedure of queen Beekeeper remove honey, feed bees Treat for varroa
July August June gap is now the July dearth Few good flowering plants Fancy garden species with double flowers have no nectar or pollen Agricultural practices have left few flowering plants Plants: lime, white clover, blackberry, annuals in hay meadows {none left}, H. Balsam Move hives to Mournes for heather
Varroa Mites
Frame with honey
September - October Colony activity slows Bad time for drones?? Wasps a serious threat Hive gets sealed for winter with propolis Last burst of laying by queen winter bees Beekeeper {remove honey}, requeen, unite weak colonies, reduce entrance, mouse guards, extract honey
September October Another critical period bees lay up stores for winter winter bees Shrubs such as fuscia, willow herb Ivy love/hate relationship for some beekeepers excellent pollen source, honey crystallizes {hard} Michaelmas daisies {asters}, Golden Rod
November - December Bees cluster A little brood is reared to replace lost bees Beekeeper add insulation in roof, treat for varroa with oxalic acid, watch for diseased and dying hives and close these up.
November December Weather/season dependent End of ivy Little foraging winter cluster Boxing day feed bees fondant
Swarming
Swarming Swarming season is May June Nuisance and loss of honey Prime swarm Old queen and flying bees Up to half colony Settle close by while scouts search Leave brood, nurse bees and queen cells 3 to 4 weeks before new queen is mated and starts to lay
Queen Cells
Cast Multiple queen cells left in hive First queen to emerge may kill rivals Bees may prevent this so this queen swarms Can be repeated until no bees left Large casts will/can survive Later casts small very poor chance of survival Beekeeper should prevent casts
