| The green shield bug does not overwinter in the larva state. Mating and egg-laying take place in early summer. A female lays up to 100 eggs. The larvae hatch and go through 5 phases of development, becoming adults in September. During these phases of development the larvae remain together. | | |
| | Map | | The map (Araschnia levana) is a butterfly species in the family Nymphalidae. There are two generations a year whose adults look significantly different. The reason for this is to find in the different day lengths (sunrise to sunset) during the development of both generations’ caterpillars. The reason for this is the differing amounts of daylight available during the caterpillars’ development. The name of the butterfly is derived from the marking on the underside of the wings, which resembles a map. This butterfly is found in Europe, Central Asia and Japan. It is beginning to spread to Scandinavia and the Baltic States. | | |

In the spring of the following year, the hatched larvae sink to the bottom of the water, where they stay for 2-3 years, until the end of their development. The larvae feed on micro-organisms. They reach body lengths exceeding 50 mm and are equipped with powerful mandibles. In the late stages of development, the larvae also catch tadpoles and small fish. | | |

The larvae hatch after 1-2 days and in the first stage of development reach body lengths of 1. 8-2. 2 mm. They feed on the dung, carrion or garbage, in which they live. In the 2nd larval stage, they are 2. 7-3. 8 mm long. At the end of the 3rd larval stage, the larvae are 13-14 mm in length and they then pupate. The p...
... live. In the 2nd larval stage, they are 2. 7-3. 8 mm long. At the end of the 3rd larval stage, the larvae are 13-14 mm in length and they then pupate. The pupae are 8. 4-9. 8 mm long and in size differ from pupae of other species of blow flies. The development time from egg to adult is approximately 38 days in total. | | |

The newly hatched larvae breathe through tracheal gills. They feed on algae, plant parts and tiny crabs. Larval development usually takes 1 year, but can take up to 3 years depending on the species. During this period the larvae shed their? skin - up to 30 times. In the final stage of development the sub-imagos (pre-adults) hatch from the larvae. The sub-imagos have milky coloured wings. The sub-imagos shed their skin to become sexually mature mayflies which have transparent wings.. Since all mayflies hatch at the same time, they occur en... | | |

The fertilized females always lay their eggs on the host plants of their larvae, on the underside of the leaves. The development from egg to caterpillar takes about 10 - 12 days. After hatching the caterpillars immediately begin feeding on the host plants and after about 60 days they have completed their development. They are greenish and have a pale line lengthwise on each side. When they have reached a length of about 20 mm they pupate. They hatch from the pupae from late July to mid September and produce the second annual generation of caterpillars which ove... | | |

The larvae overwinter - unlike those of other kinds of shield bugs - under the bark of trees, and their further development takes place on broad-leaved trees. | | |

The whole brood of the hive are fed with royal jelly during the first three larval stages, thereafter, the larvae of the workers receive more honey or pollen, while the larvae of the queens are given royal jelly until the end of their development. Royal jelly contains amongst other things, carbohydrates, protein, B vitamins and trace elements.
The production of royal jelly takes place in specialized hives/ OR is a specialised form of beekeeping and involves more or less complicated proce... | | |
