| The Western honey bee is a social insect. The queens reach a body length of 15 to 18 mm, the drones, 13 to 16 mm and the workers, 11 to 13 mm. The drones have larger compound eyes than the workers. Workers can in principle also lay eggs, but are usually prevented by a chemical messenger - a substance excreted by the queen. | | |
| A colony of bumblebees can consist of up to 600 insects with a queen. The majority of bumblebees are workers who live beside the male drones and young queens. In Europe bumblebees survive only one summer. Drones and workers have a life expectancy of 3 to 4 weeks, while a queen lives for approximately 1 year, during which time it hibernates for 8 months. There are, among bumblebees, socially parasitic species (Cuckoo bumblebees) which leave their eggs in the nests of fe...
...rasitic species (Cuckoo bumblebees) which leave their eggs in the nests of fellows and let the fellows care for their breed. The larvae of the cuckoo bumblebees danger the fellows’ own breeds since they eat the eggs and larvae. These species have no workers. | | |

After the larvae have hatched the queen takes care of the brood, feeding the larvae with insects and spiders until they pupate in early June. These larvae will become the female workers. As soon as the young female workers have left their pupae, they take over nearly all activities of the queen, who then almost exclusively lays eggs, up to 40 a day in late summer. With strong heat the female workers move their wings, in order to cooling of the nest and thus to save the brood from too much heat. | | |
| | A hierarchy develops amongst the female workers of the new hornet colony which resembles the pecking order amongst chickens and this can create aggression, which leads to more or less heavy fighting between individual female workers. When this happens workers may sting each other resulting in deaths. If the population of the nest expands greatly and there is no room for further development all the hornets move to a more suitable place and establish a new nest (branch formation). | | |
| | Vespinae living in colonies build nests in dark caves, trees, hedges or attics. A single state with a queen, workers and drones can comprise up to 7000 insects. Labour is organised - the Queen only lays eggs while the workers are responsible for nest building , nest cleaning, food procurement and feeding the larvae, and the drones are responsible for the fertilization of young queens. To avoid inbreeding, some drones leave the nest and look for females from other popula... | | |
| | ...permanent nests or be nomadic. They are highly organized and have a social stratification system (caste system), with each insect performing a particular task. Several million ants can live in a colony. Most of these are infertile females and are workers or soldiers with duties both outside and inside the nest.
Only the queen ant can produce eggs. The males - like the young queens – have wings, and their only task is to fertilize the eggs. The workers and soldiers are much smaller than the queens. They have poison glands on the abdomen which at many species are connected with poison stings. | | |
| | The queen bee is 15 to 23 mm in length, while the, workers and drones are approximately 8 to 21 mm. Bumblebees have a strong rounded body, comprising head, thorax and abdomen. They are protected from the cold by hair which is mostly yellow, white or black in color. The colouring of the bumblebee varies f... | | |
| | ...ies the abdomen also has yellow, orange or red hues. The most noticeable characteristic? of the honey bee is the narrow and elongated radial cells on the forewings. The sides of these cells are almost parallel and only slightly curved. Queens and workers have a poisonous sting, however the queen’s has degenerated as a result of egg laying. | | |
| | Bombus pascuorum | | ...y common bumblebee. It is one of the colony building insects. The head, chest and back are brown in colour with the abdomen of some insects being bright or dark. The queens reach a body length of up to 22 mm, and the drones, up to 18 mm while the workers are considerably smaller. The Bombus pascuorum can be found in meadows and clover fields, but also in walls and buildings. It feeds on nectar and pollen, preferring the flowers of fruit trees, large-flowered hemp-nettle, motherwort, deadnettle and ... | | |
| | Bombus lapidarius nests in stone walls or clusters under piles of rocks. It is also found in straw in stables or in abandoned bird nests.
A colony of Bombus lapidarius comprises 100 to 200 workers. They prefer nectar from clover and deadnettles. In 2005, Bombus lapidarius was the Insect of the Year.
