| Western honey bees are brown in color. In some sub-species 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. | | |

For this purpose they dig a main gallery, which is up to 60 cm deep and leads into the ground, and into diverse brood cells (incubators). The entrance to the nest looks like a crater surrounded by a small mound. The brood cells are filled with a pulp of pollen and nectar by the females and afterwards they lay an egg on this mixture. A few days later the larvae hatch. The development of the larvae to the point of pupation takes a few weeks. The pupae overwinter. | | |

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 of the exine antheres forms and nourishes the pollen grains. Pollen is spread by wind, water or living organisms. This also leads to pollination.

The Anthidium manicatum lives on nectar and pollen, which it collects from plants such as Stachys, sage or motherwort. It nests in pre-existing holes in earth, masonry or wood. The females build individual cells for their eggs using pieces of leaves bound together by a substance they secrete. They then supply each cell with pollen or nectar, before introducing an egg into the cell. After egg-laying the cell is sealed. When the larvae hatch, they live ... | | |

The fertilized females lay their eggs in spring in the nests of their larvae’s hosts. This happens near the brood-cells which have adjacent food stores. The young larvae hatch after a few days and start eating the host’s eggs or larvae. Later on they feed on the stored nectar and pollen. Pupation takes place in a cocoon within the host’s breeding cell.

The nest is made from a paper-like material, mostly won made of poplar bark. The nest includes brood cells, where the eggs are stored and the larvae develop. The larvae are fed a meat pulp made of insects, preferable Diptera. When the first female workers have hatched, further construction of the nest, and the provision of food supplies for the larvae is... | | |
| | While the males in autumn die after mating, the females overwinter hidden. In spring they dig a nest, which consists of the main course (leading diagonally into the earth) and several short side galleries leading to the cells for the brood. They lay one egg only in each brood cell. The egg is located on a nectar pollen mixture, which (as food for the larvae) also is introduced to the brood cell. In summer the bees of the new generation slip. The parent female specimens s... | | |

The nests are often found in buildings, garages, sheds or blindboxes. When finished, nests consist of about 50 cells. They have no protective outer surface. Up to 30 workers live in a single nest. At the end of July, the adult females and males of the new generation appear. In September the wasps die with the exception of the fertilized young queens, which hiberna... | | |
| | The andromeda lace bug is only seen in daytime and feeds on plants (phytophagous). As it is not inclined to move much , it is mainly found on the undersides of the leaves of the host plants. It sucks fluid from the leaves’ cells , which causes the leaves to yellow and eventually fall off. Thus the whole plant loses its leaves from top to bottom . Often the host plants die. Some examples of the plants which the andromeda lace bug prefers to eat are : heather species (Eri... | | |

Lace bugs feed on plant juices, which they remove from the epidermis layer of the leaf undersides with their piercing and sucking mouth parts. When the leaf cells are empty, the damaged area is discoloured bronze or silver. Each individual spends its entire life on the one plant, if not on the same plant part.
