| 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 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. | | |
| | Bumblebees | Bumblebees (Bombus) are a genus of social bees. Since these Hymenoptera have a sting for defence, they belong to the stinging bees. There are approximately 250 species of bumblebees. They live mainly in the temperate and cooler areas of the northern hemisphere. There is a particularly large variety of species in Europe and Asia; In Europe there are approximately 70 species, 36 of which can be found in Germany. Examples of Eur...
...which can be found in Germany. Examples of European bumblebee species are: Bombus argillaceus, Bombus jonellus, Bombus subterranus, Bombus veteranus, Bombus alpinis, Early Bumblebee, Bombus pomorum, Bombus pascuorum and Bombus sicheli. 16 species of bumblebees are currently threatened with extinction. | | |
| | | Bumblebees (as well as bees in general and flies) are among the most important crop pollinators. Some of the most important natural enemies of bumblebees are: Cuckoo bumblebees, Anthidium manicatum, Mutilla and thick-headed flies. | | |
| | 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 from type to type. Bumblebees eat using a proboscis, which can vary in length. They have one pair of compound eyes , antennae and six legs.

| Females lay their eggs on sitting or slow flying host animals, especially on bees, bumblebees, wasps, or sometimes grasshoppers. They cling to the host animal and lay eggs between the segments of their abdomen. The hatching larvae then eat their way into the abdomen of the host animal, reside there and feed on the insides of the host until i...
...men of the host animal, reside there and feed on the insides of the host until it is hollow. The larvae overwinter in the host insects. Some species, such as Conops flavipes (the most common species of the genus Conops) live in the nests of bees and bumblebees where their larvae feed on the bee brood. | | |

When the labor force hatches the nest expands to accommodate up to 500 bumblebees. Nests in soil can have a depth of 1.5 metres. Bombus terrestris live from March to October and are found in forests, on meadow slopes, and in gardens or fields. They can be encountered from the lowlands to the mountains. The workers of the Bombu... | | |
| | The shrill carder-bee | | Bombus sylvarum is an annual colony building insect species which belongs to the bumblebees. Bombus sylvarum are widespread in Germany and Europe although they are rare in the north (of europe or germany. They inhabit forest edges, parks, gardens, meadows, ditches and embankments. Bombus sylvarum prefer flat areas. | | |
| | Sicus ferrugineus are diurnal and can be found from May to September in a variety of habitats inhabited by bumblebees. The adults are avid flower visitors, feeding on nectar, pollen and honeydew, especially from thistles, blackberries or the parsley family. | | |
| | After mating, the fertilized females lay their eggs singly on bumblebees, ambushing the workers in flight. They cling to the host animal and lay their egg between the abdominal segments. The larvae hatch quickly and then eat their way into the abdomen of the host and hollow it out gradually. Sicus ferrugineus larvae pupa... | | |
