Beekeeping and the Sweet Honey Bee


honey bee/apis

Honey (fra Germanic: honang = "the golden")  is the storing-nutrients of the honeybees which they use in connection to overwintering. The bees gather nectare from flowers but also sugar from the excrements of the aphids, known as honeydew, and from nectaries in ferns and on leaves from some hardwoods.

The colour of the honey mostly comes from the flowers from where the nectare is taken - and it can be from white-yellow til greenish black. The taste also depends on which flowers the bees have visited. Clover and lime honey are light and mild, while heather honey, lavender honey and rosemary honey are dark and spicy.

The type of honey can always be determined by examination of the pollen grains in the product.

Honey types:
flower honey ( mild with a fine characteristic scent)
forest honey (dark, neutrally sweet)
heather honey (dark and spicy)
herb-honey (each spice delivers a dark and very characteristic honey)
rape-honey (very mild, light with a quick crystallization)
clover-honey (mild, light and with a gentle taste).

In addition is also the artificial honey made from sugar, glucose and fruktose

Honey is used as a herbal medicine but mostly in German-speaking countries, where they have a long tradition to value the preventive effect on the health. It was known since antiquity that honey works antiseptic  - and the Egyptians used honey for treating wounds.


The content of antioxidants enzymes, vitamins and minerals make honey a more healthy product than pure sugar.

Some bacterias can survive in honey which makes the product unsuitable for small children under 12 months. Their gastric fluid is not yet sour enough to kill the harmful bacterias -  and eating honey might give them a serious food poisoning( fx botulism) ( netdoktor.dk ) 


Before humans made sugar from sugar cane, honey was a very important and sought for sweetener, and often the only one known. Today honey is used as a laying on and as a sweetener which brings a characteristic mild taste to dishes, desserts, cakes, candy and drinks.


Globally are more than 20.000 species of wild bees.

Harvesting honey from wild bees is one of the earliest human activities and is still being practized in some  native societies i Africa, Australia and South America. Beekeeping was known by humans for thousands of years. At some point humans began to attempt to domesticate wild bees in artificial hives made from hollow logs, wooden boxes, pottery vessels, and woven straw baskets or "skeps". Traces of beeswax are found in pot sherds throughout the Middle East beginning about 7000 BCE.
 According to legend the Irish Saint Modomnoc introduced the beekeeping in Ireland in the 500s.


cave painting, 15.000 years ago
Depictions of humans collecting honey from wild bees date to 15,000 years ago. The honey was usually being collected by pacifying the bees with smoke and then break the tree or the cliff where the bee-colony lived which resulted in the destruction of the colony.Beekeeping in pottery vessels began about 9,000 years ago in North Africa. Honeybees were kept in Egypt from antiquity. Domestication is shown in Egyptian art from around 4,500 years ago. Simple hives and smoke were used and honey was stored in jars, some of which were found in the tombs of pharaohs such as Tutankhamun.





stele, Mesopotamia 760 BCE
There was documented attempt to indtroduce bees to dry areas of Mesopotamia in the 8th century BCE by Shamash-resh-usur, governor of Mari and Suhu. His plans were detailed in a stele of 760 BCE.

In ancient Greece the god Aristaios was the shepherd god for beehives. Beekeeping was also very specifically addressed by the Roman writers of antiquitiy like Virgil, and the life of the bees were described by Aristoteles.

In prehistoric Greece (Crete and Mycenae), there existed a system of high-status apiculture, as can be concluded from the finds of hives, smoking pots, honey extractors and other beekeeping paraphernalia in Knossos. Beekeeping was considered a highly valued industry controlled by beekeeping overseers—owners of gold rings depicting apiculture scenes.

Archaeological finds relating to beekeeping have been discovered at Bronze and Iron Age archaeological sites in Israel in the ruins of a city dating from about 900 BCE. Beekeeping has also been practiced in ancient China since antiquity. In the book "Golden Rules of Business Success" written by Fan Li (or Tao Zhu Gong) there are sections describing the art of beekeeping, stressing the importance of the quality of the wooden box used and how this can affect the quality of the honey.


P. Bruegel 1568: Beekeepers.
Beekeeping, 14th century

It wasn't until the 18th century that European understanding of the colonies and biology of bees allowed the construction of the moveable comb hive so that honey could be harvested without destroying the entire colony.

The Bees are buzzing now................



What happens in Spring?


When the temperature is above 7-8 Celsius the bees wake up and start their work. A bee family has about 20.000 working bees in early spring. The bees have been waiting through winter in the beehive and in the center of the bees is the queen, well protected from the cold.



In the first month of spring the bees gather pollen,  especially the yellow catkins of the willows give an important source of protein. If you get a close look at a bee  near a willow tree, you'll see it wearing big pants filled with golden pollen. The bees, who are fed with pollen in spring, are the same who are pollinating the fruit trees in April and May. While gathering pollen the working bees are vey busy, they have to fly 20.000 trips to cover the need of pollen for the beehive. If it is raining, the bees have to use the deposits from the previous years. But when summer arrives they can gather more pollen than they use.

The Queen bee lays 200 eggs in each 24 hours during April. Almost all eggs are working bees, unfertilized eggs are male bees or drones. They must be hatched in April to reach maturity for the swarming season in May. All the other eggs are female bees, but only the Queen bee can lay eggs.



When summer is near the number of bees in the family have raised till 60.000 -  and with so many bees in the same family, the Queen bee cannot control them anymore. The working bees build one or several special cells - Queen cells. They are larger than the working cells and hang down vertical. The Queen bee lays a common fertilized egg in the queen cells. When the eggs are hatched the larvae is fed with a special fodder - gele royal . This makes the larvae grow fast and be larger than the working bees. The larvae will become a new Queen.

Before the new Queen leaves her cell, the old Queen collects about half her subjects and leaves the beehive - she knows, she will lose to the new Queen if she stays. The old Queen and her following subjects gather in one big brown living lump upon a tree or a branch. During the next many hours some bees fly to and fro the place of residence, they are scouts looking for a new place where the bee family can live. When they come back to the other bees they tell them about their discoveries by dancing a special dance outside the lump. And when many scouts are dancing the same dance, they are telling about the same place. The big swarm flies up again and leaves and the scout bees fly through the swarm again and again to lead them to their new residence.

The Bee is Wiser than they thought....


















Scientists have discovered so much by the help of the fantastic computers through the last years, but they have also found out that the little busy bee can be both faster and smarter than any computer. The small-brained bees have solved a mathematic problem, which might keep modern computers working for days and days.

Two scientists from two London universities have found out that bees learn to fly the shortest possible distance between the flowers, dependent on the order, in which they have discovered the flowers. In other words; the bees have solved the classic mathematic problem "The Travelling Salesman".

The challenge about this "travelling salesman" has been formulated and solved by a clever Irish mathematician, Sir William Rowan Hamilton, and it deals with the problem of a salesman, who has to visit several cities once via the shortest possible route.

Computers can solve this by comparing the lenghts of all possible routes and then choose the shortest. The bees solve this as the first animals without any help from a computer. A scientist from The School of Biological Science explains that foraging bees solve this complex mathematical problem each day. They visit numbers of flowers each day - and since they need large energy ressources to keep on flying, they must find a route, which makes the flying trip as short as possible. And they know how........

Viper's Buglos / Slangehoved

Echium vulgare



Viper's buglos is native to most of Europe and west and central Asia. This wildflower is found on disturbed dry soils, dunes, shingle, cliffs and open grassland. It is a good nectar plant, attracting lots of bees. On warm days the brilliant blue flowers are covered in honey bees and bumblebees.

Other names are Blue Devil, Blueweed, Thistle and Viper's Grass. The genus name echium comes from the Greek word Ekbis = viper. The viper part of the name may derive from the spotted stem said to recall marks on a snake, or an imagined resemblance between the flower-head and the head of a snake. Viper's buglos is an example of a wildflower that received a frightening name based simply on its looks. Some people thought that the plante created a hiding place for snakes or that the plant was guilty of other serpent-related qualities.

A red dye is obtained from the root.

Medicine.
Actually Viper's buglos was once considered to be a preventive and remedy for snake bites. Traditional the leaves of the plant were boiled and made into a tea which helped fevers and headaches or made into an infusion for nervous complaints.

Sticky Catchfly/ Tjærenellike

Lychnis viscaria



Sticky Catchfly/Tjærenellike is a very attractive plant with dark pink flowers on a tall stem, which is sticky just below each pair of leaves. The plant is said to increase the disease resistance of surrounding plants. Extract from it contains a relatively high amount of brassino-steroids, which have a proven positive effect on the growth of other plants. In Germany the extract is allowed for use as a 'plant strengthening substance.' Sticky catchfly is native to Europe, Asia and North America.

If you pluck it, your fingers almost fasten in the tar-like paste on the stem, and if you look closely you'll see little dead and half-dead insects in the paste. The English name sticky catcfly is well-chosen. It is not a carnivorous plant though - on the contrary it has lots of nectar for bees and butterflies. In fact it is one of the best nectar plants in Denmark. On the other hand the plant wages war on the insects that try to steal the nectar, the so-called nectar robbers, fx ants. They empty the flowers of nectar without pollinating them , and insects on their way up fasten helplessly in the paste on the stem. Mother Nature is really smart.

The Honey Bee is in Danger.



Life has gradually become an obstacle race for insects like honey bees - they live by flying from flower to flower and return to their large family with pollen and nectar which they change into honey.

Poison, slurry and gigantic corn fields do not harmonize with the bees' need for a clean environment with lots of flowers, bushes, trees and various crops. The development of the industrial agriculture has created a visible distance between the flowers in the landscape, and the population of Danish bee-families have gone from ab. 200.000 in the years around 1950 till ab. 80.000 in these years. The work of honey bees from early spring till late autumn is of crucial importance for the diversity in the nature.

The honey bees are among the most important assistants for the fertility of the flora. Also for the hundreds of plant species which are used in farming, foresting and in the gardens are the bee- pollination of crucial importance. Crops like winter rape and clover are completely dependent on the bee-pollination. Also all plants which seed, like fruit trees, berry-bushes and other similar plants. Danmarks Jordbrugsforskning (research) has estimated that the Danish honey bee- pollination only in the agriculture and in fruit and berry-cultivation represents a value of at least 1 billion kroner. The EU-commission is more concrete in its evaluation of the good deeds of the bees when it's about money. According to EU the bees' work represents ab. three billion kroner a year. (in DK) At the same time is concluded that the value of the pollination of the bees and the following fertility is 30-50 times higher than the value of the honey-production which in Denmark is ab. 60 million kroner a year.

The industrial agriculture has meant that the fields grew larger and larger. Stone-fences, earth banks and lots of hedgerows disappeared, and the distance between the small uncultivated oases for the flowers and bees grew longer and longer.



The verges and ditch-edges were once a study in a diversity of flowers which were good for the honey bees and other pollinating insects. Today are only few plant-species in those places. The heaths are attractive for the bees, but they are now in a crisis, caused by nutrient-rich precipitation. The nitrogen gives several grass species good living conditions at the expense of the heather.

The honeybee and all other pollinating insects lost terrain when 117.000 hectare fallow fields were ploughed and cultivated in 2008 - an area the size of the island Lolland simply disappeared as a habitat for bees.

All in all - the honey bee, the bumblebee, the butterflies and other pollinating insects are in danger. Some species have already disappeared never to return. Fewer pollinating insects will effect us more than we imagine right now - also in our daily economy. Fewer vegetables, berries, fruit will empty our pockets! So it's best for all of us, if there are more uncultivated places for bees, butterflies and other pollinating insects.
