| Adult Sicus ferrugineus reach body lengths of 8 - 14 mm. The body size depends on the size of the host in which the larvae develop. The essentially rust-red body colour is sometimes black-brown, yellow, brown or reddish- brown. | | |
| | ...ong proboscis and is as long as the female body and only slightly shorter than the male’s. Due to its appearance, the acorn weevil can be confused with a related species, the hazelnut weevil (Curculio nucum). They can be differentiated by their body size: the acorn weevil is slightly smaller, and by the size of the probe beam - in the hazelnut weevil it is twice as long as wide, while in the acorn weevil the length is three times the width. | | |

Beetles can vary enormously in size ranging from 170 mm in length (Titan beetle in Brazil) to lengths of 0.5 to 75 mm (European species). The largest beetle in Germany and Central Europe is the stag beetle. | | |
| | The wasp nests of Dolichovespula saxonica, are built from rotting wood, are grey in colour and are approximately the size of a ball? football or tennis ball or what? The whole exterior surface of the nests is smooth. While the adult animals feed mainly on nectar, the larvae are fed on flies. The life cycle of Dolichovespula saxonica is approximately April to Sept... | | |

The exine has two-layers and consists mainly of sporopollenin. The structure is determined by the pollen grain. Pollen grains vary in size, shape and surface structure, so that it is possible to identify what plant genus and species they come from. Pollen grains reach average sizes of between 10 and 100 microns. They have one or more apertures, which lack the outer layer of the exine so that the intine can grow through into a pollen tube.
Pollen grains are usually spread singly (monads) but may also be released into the ... | | |
| | Armadillium (Pill woodlice) | | ...armadillium is smooth. The armadillium has a high resistance to water shortages. Therefore, it is also found in forest edges and ruderal on plants growing on waste ground or among refuse.
The females breed up to 3 times a year. Depending on the size of the female, from 20 to 160 young isopods hatch.

A colony can accommodate as many as 200 wasps. The nest can grow to approximately the size of a football. In August additional males and young queens are bred. The young fertilized queens seek out winter hideouts, while all the other wasps die. | | |
| | The size of the blow-fly varies greatly. For the sake of example the Cynomya mortuorum can reach a body length of up to 18 mm. The body of the blow-fly is compact and often shiny metallic blue, green or golden-green in colour. In addition to their well deve... | | |

During their development (3 to 5 years) they profit from the warmth created by the decomposition of the plant material. The mature larvae pupate in a cavity approximately the size of an egg, surrounded by a cocoon. The adult beetle hatches and remains in this dwelling for a few weeks. Adult rhinoceros beetles can be observed outdoors from June onwards. They fly at night. Their life expectancy is around 4-5 weeks. | | |
