Pollen grains are usually spread singly (monads) but may also be released into the air in groups of two or four (dyads or tetrads). Pollenkitt is capable of holding pollen grains together in groups. This can also be done with sticky threads of sporopollenin, cellulose or protein. Each 4 pollen grains are formed simultaneously in pollen sacs of pollen mother cells. The pollen sacs are situated in the anthers of the stamens. The innermost layer ... | | |
| | It feeds on nectar from thistles and cornflowers. In May or June the females lay about 100 to 300 eggs in groups on the host plants, on the undersides of the leaves. The caterpillars hatch after about 2 weeks and are yellowish-green and spotted black. They eat in groups. The older larvae are solitary. The caterpillars can be encountered from June to October and reach lengths of up to 40 mm. They develop a clear warning sign, and are equipped with a chemical defense system which is based on sulphur compounds and der... | | |

The small commons primarily enable the solitary bees to rear their offspring together and temporarily to protect themselves. Even sleeping, hibernation and guards groups are formed. Bees which live in colonies however, are non–transient , socially sophisticated and almost perfectly organised.
For humans primarily the honey bee is of interest. There are 9 different species : Apis dorsata laboriosa, Dwarf honey b... | | |

Beetles are often divided by humans into two groups: those that are harmful and those that are beneficial. Sitophilus oryzae and wheat weevil can cause significant damage to cereal stocks, while the Colorado potato beetle, Meligethes aeneus and Western corn rootworm are able to destroy entire harve... | | |
| | Andrena | | Andrena are a genus within the bee family comprising more than 1500 species and about 100 sub-groups. 150 species are found in Europe 110 of which can be found in Germany. The latter include the Andrena vaga, Andrena fulva, the Andrena cineraria and the Andrena haemorrhoa. | | |

The female Bibionidae lay up to 3,000 eggs, individually or in small groups in the soil, where they are buried. The hatched larvae, which are resist to the cold, are usually hairy and are found en masse (especially in the upper layers of humus). They live on rotting plant remains and are important soil regenerators. The ... | | |

Honey can be divided into groups according to the extraction method?: From the procedure honey is won there is strained honey, sliced honey, comb honey, drained honey, pressed honey and stamped honey.
Honey can pose a risk to humans. Honey can contain Clostridium botulinum spo... | | |
| | Common red soldier beetles live in forests, fields, meadows and gardens. They are to find (often in groups) on flowers or leaves. They are active by day and feed on insects, young plants extensions or pollen. | | |
| | The firebugs occure in different stages of their development. The animals accumulate to groups depending on the release of hormones by them, as called pheromones. If the firebugs (at risk) set free defence secretions, their meetings immediately solve. | | |
| | They suck the juices from various plants, including Umbelliferae, hogweed and cow parsley.
Mating usually occurs in spring, but sometimes in summer. The females lay their eggs (by gluing them) in small groups on leaves and stems. After 8 - 10 days the larvae hatch and are guarded for a while. (sounds a bit vague) Graphosoma lineatum overwinter as adults. | | |
