Beekeeping for Beginners
Session Four –The Colony
Tutor - Derek Evans
THIS SESSION: We will look at
1. Who makes up ‘The Colony’?
2. What are the Individual Life Cycles of The
Colony?
3. What are the jobs of the bees?

How many in The Colony?
Summer Winter
▪ Queen – 1 1
▪ Worker – 60,000 10,000
▪ Drone – 200-2,000 0
Summer – June/July
▪ 5,000 – 7,000 eggs
▪ 7,000 – 11,000 larvae being fed
▪ 16,000 – 24,000 larvae pupating into adults in sealed
cells
Number of bees in The Colony
Nectar flow
May to July
Nectar v Honey
Raw Material for the bees
Nectar consists of around 60%-80% water with a little
sugar, organic acids, and a handful of amino acids that add
flavours and aroma attractants for the pollinators.
Finished product from the bees
Honey is nectar that has been enzymatically treated by bees
(to convert and rearrange some of the sugars) and then
dehydrated to around 18% - 20% water, producing a
concentrated sugar solution which can be stored for long
periods
Head of a bee
1. Eyes
▪ 3 Ocelli eyes
react to light & movement
▪ 2 Compound eyes
Queen 3,000 – 4,000 facets
Worker 4,000 – 6,900 facets
Drone 7,000 – 8,600 facets
2. Antenna - taste,touch,smell
3. Mandible - jaws
4. Proboscis - tongue
1. Hypopharyngeal gland – initially to produce royal jelly
2. Wax gland
3. Sting gland
4. Hypopharyngeal gland – evolves further to produce enzymes to process
nectar into honey
5. Nasanov gland – attraction scent during swarming
RECAP 1. Head 2. Thorax 3. Abdomen
Queen
▪ Queen hatches from a fertilised egg
▪ On her mating flight she mates with up to
20 Drones (Drones then die)
▪ Her temperament affects the whole
colony
▪ Pheromone(or queen substance) informs
colony all is well
▪ 30 minutes for a colony to realise that she
is missing
▪ She lays up to 2,000 eggs a day in summer,
nearly zero in winter
▪ Queen attendants(workers) – feed, encourage
her to lay, grooming, remove her excrement
▪ Can only sting another queen
▪ She can live 2 to 5 years
Drone - (male)
▪ Drone hatches from an unfertilised egg
▪ Sole job is to mate with a virgin Queen
▪ Drone Congregation Area
▪ Drones do not have a sting
▪ Fed by worker bees
▪ Not loyal to one colony
▪ In early Autumn, all the Drones are
evicted and die!
Worker – (all female)
▪ Worker hatches from a fertilised egg
▪ 6 weeks in the summer
▪ 6 months in winter
▪ Sting - defence mechanism to protect the
colony
▪ Work until they die – more to follow after
the coffee break!
2. Individual Life Cycles Developmental stages
Comparison of the Individual Cycles
Egg stage 3 3 3
Larva stage 5 6 7
Pupa stage 8 12 14
Emerge as adult 16 days 21 days 24 days
Lifespan as adult 2 to 5 yrs 6 wks (summer) 3 months
6 mths (winter)
Eggs hatch after first 3 days (1 - 3) into larvae
Second 3 days (4 -6) all larvae fed royal jelly
After day 6 worker (7 – 9) and drone (7 – 10) fed brood
food – higher % of hypopharyngeal secretion
Queen (6 – 8)
larvae fed royal jelly for a further 2 days
What is Royal Jelly and Brood Food?
Royal Jelly:
▪ Secreted from the hypopharyngeal gland of the
worker
▪ Mixture of pollen(protein), nectar (24% carb), enzymes,
amino acids
Brood Food/Bee Bread:
▪ Gathered & stored in cells
▪ Mixture of pollen(protein), nectar (12% carb), yeasts

12 bees to make a

6 weeks in summer
Let’s take a break
then we’ll
consider the bees
division of labour
3. What are the jobs of a worker bee?
Life of a worker bee can be divided into:
1. Hive/House Bee – first 3 weeks0 to 10th day = nursing/welfare
10th to 21st day = food storers
2. Field Bee – second 3 weeks21st day plus = forager

Propolis Water
What is propolis?
▪ Resinous sticky gums and balsams from various
plants and trees. Common sources are :- Alder, Birch,
Cherry, Peach, Plum, Conifers, Hazel, Horse Chestnut,
Oak, Poplar & Willow
▪ Resins mixed with salivary enzymes, wax, other
foreign materials such as wax moth scales, hive litter
and organic debris. Approx. recipe is 50% resins &
balsams, 30% wax, 10% essential oils, 5% pollen & 5%
organic debris

2. The Individual Life Cycles - EGG TO HATCH
3. The jobs bees do - HATCH TO DISPATCH
4. Communication – PHEROMONES/DANCES/
ODOURS

How do Bees Communicate?
Methods of communication:
▪ Pheromones
▪ Floral Odours
▪ Bee Dances
▪ A pheromone is a chemical message which
changes behaviour
▪ Instant change eg nasonov gland, sting
▪ Slow acting eg queen substance
Bee DancesDances incl. variables e.g. tempo, buzzing
▪ Shaking signal (wake up foragers)
▪ Round Dance (distance < 50 metres)
▪ Sickle Dance (distance 50 to 150 metres)
▪ Waggle Dance (distance & direction > 150 metres)
▪ Tremble Dance (activate food storers)
