Honey in the City
There are nearly 20,000 known species of bees in seven to nine recognized families, though many are undescribed and the actual number is probably higher. They are found on every continent except Antarctica, in every habitat on the planet that contains insect-pollinated flowering plants.
Bees are adapted for feeding on nectar and pollen, the former primarily as an energy source and the latter primarily for protein and other nutrients. Most pollen is used as food for larvae.
How long is the biggest bee?
They have a long, complex "tongue" that enables them to obtain the nectar from flowers. The antennae are almost universally made up of 13 segments in males and 12 in females, as is typical for the superfamily.
Tiny stingless bee species exist whose workers are less than 2 mm (0.079 inches) long. The largest bee in the world is a leaf-cutter, the females of which can attain a length of 39 mm (1.5 inches). Members of the family Halictidae, or sweat bees, are the most common type of bee in the Northern Hemisphere, though they are small and often mistaken for wasps or flies.
Honey bee as the most popular amongst them
The best-known bee species is the European honey bee, which, as its name suggests, produces honey, as do a few other types of bee. Human management of this species is known as beekeeping or apiculture.
40,000 new Sika employees: bees on the green roof
Sika Sarnafil in Champagne au Mont d’Or, France, is doing an amazing job ensuring biodiversity in the city. In 2005, they put a Sarnavert green roof from their own production range on their office building and later installed two beehives up there, which they share with another company. This was the beginning of a new friendship. The bees feel very comfortable on the green roof and are treated like 40,000 new Sika employees and clients can visit them as a model.
Each hive produces 15kg of best honey
The first crop of honey was harvested in September 2014, each hive producing 15 kg. This is quality honey, guaranteed pesticide-free, made inside a city. The hives are maintained by a Sika technician, while a beekeeper is responsible for harvesting. The honey bears the Sika label, and with a bit of luck you might get a pot from your Sika Sarnafil France dealer after the next harvest!
Bees are essential for ecosystem
Bees play an important role in pollinating flowering plants, and are the major type of pollinator in ecosystems that contain flowering plants. They either focus on gathering nectar or on gathering pollen, depending on demand, especially in social species. Bees gathering nectar may accomplish pollination, but bees that are deliberately gathering pollen are more efficient pollinators. It is estimated that one third of the human food supply depends on insect pollination, most of which is accomplished by bees, especially the domesticated European honey bee.
Bees are responsible for 30% of human food supply
Contract pollination has overtaken the role of honey production for beekeepers in many countries. Monoculture and the massive decline of many species (both wild and domesticated) have increasingly caused honey beekeepers to become migratory so that bees can be concentrated in seasonally varying high-demand areas of pollination. More and more green areas in an urban environment should be used to give bees a new habitat. And remember: you will get honey afterwards. And never forget that these small creatures are responsible for a substantial 30% of our food supply. So we should treat them well.
