| ... 100 mm and pupate in the period from July to August in tunnels, which are about 80 mm deep. The pupal period lasts 4 - 6 weeks. In late September or early October of the 4th year, up to 200 great capricorn beetles hatch in a single tree. The entire development period of the larvae can be up to 5 years. | | |

| ...ating season is fromJuly /to September. The fertilized females lay their eggs just below the surface of the soil (usually in chaff or leaves). The larvae of Lagria hirta are cream to light brown in colour. They feed on rotting leaves or on peat. The development of the larvae from egg to beetle takes 9 months, from autumn to spring. Lagria hirta overwinter in the larval stage. In May of the following year, the larvae pupate and hatch as adult beetles. | | |

|
| 4 to 5 weeks after hatching, the development of the nymphs is complete. The winged juvenile bugs mate very quickly. Egg laying by the first new generation occurs in late June / early July singly in the leaf tissue of herbaceous plants. The nymphs hatch in midsummer. The specimens of the second... | | |

| Adult rubytail wasps reach body lengths of 4 - 13 mm. Their size depends on the conditions of development? environmental conditions present during the larval stages. Their bodies are slim and vary in shape. The head and chest (thorax) are bright blue-green in colour. The upper surface has a metallic gold sheen. The upper surface of the abdomen shimmers ... | | |

| ...st’s nest and pupate, either immediately, and then either to fly as another summer generation in the same year, or to overwinter inside of the cocoon. This assumes that the host larvae overwinter as well. The rubytail wasp is able to synchronize its development with the annual cycle of the various host larvae. | | |

| ...lay their eggs in ‘packages’ in wet or muddy ground. The eggs overwinter there. In spring the eggs are transported into water by the rain. The pre-larvae soon hatch from their eggs and fully develop into larvae. At the end of June, after one year of development, the larvae emerge from the water as adult dragonflies. | | |

| ...ider silk in the creases in leaves, rolled up leaves or under rocks for their eggs. Having finshed the cocoon, they spin themself a roof shaped shelter in which to reside, while guarding their brood. The spiders hatch and reach their final stages of development in autumn. The young spiders overwinter under loose bark. On warmer winter days they leave their shelter for a few hours to walk around. | | |

| ...animals in different ways. Firstly through ingestion of their eggs, secondly through oviposition directly on the host animal, or thirdly through the hatched larvae’s direct entry into the host animal. Usually the host animals die before the larvae’s development is complete. The pupation of the larvae usually occurs outside the host animal.
Since the larvae of many tachina flies kill pests, they are very welcome in the agriculture and forestry industry. | | |

| ... to stripes and disc formation. The hatched larvae (nymphs) are a variety of colours and have no wings at first. These grow from the 3rd larval stage on (after the 2nd moult). The young bugs have their defense glands on their backs. In September the development of the nymphs is complete and after the last moult they emerge as fully developed adult bugs. | | |
|
| Adult Scatopsidae like to rest on parsley, to feed on the nectar. They are often found in rural residential areas, as these generally provide favourable conditions for the development of their larvae. | | |
