|...not initiated through courtship by the males, takes place in May/June. Through the use of a special grip, the male spiders avoid the femaleís deadly bite and leave after mating. In order to store the fertilized eggs, females produce a dark green cocoon , and encase it in a fine white web. . The cocoon is attached to parts of plants (mostly leaves) and is guarded and protected against predators by the mother until the young spiders hatch, which takes about 100 days.|

Approximately 14 days after the rubytail wasp larvae hatch, even the food supplies of their hosts (only insects, no pollen) have been consumed, and they spin a cocoon for themselves in the hostís 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. |
|After mating, the females erect a cocoon for the eggs. The white cocoon is 6 - 7 mm in length and is hidden, at a slight distance from the hideout of the spider. After reaching maturity (after the last moult) the life expectancy of the males is very short, and most die shortly after mating. |
|Mating season is in May. Most males die after mating - those that survive can be encountered until July. The females spin a flat cocoon covered with light coloured spider 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 ...|

Eggs are laid on the soil or on grass. The caterpillars shed their skin twice. They overwinter and pupate in May. The cocoon is spun on a blade of grass and is yellowish-green. The next adult meadow browns emerge in June.
The meadow brown is active from June to September. It reproduces once a year. |

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. |

The female autumn spider creates several white, round cocoons onthe branches or the bark of trees for the protection of the eggs. Up to 100 yellow eggs are laid in these cocoons. A few days later the female autumn spider dies. The eggs overwinter in the cocoon. The new generation hatches in spring.
Some natural enemies of the autumn spider are: insectivores, birds and other spiders from the family pirate spiders (Mimetidae), for example species of the genus Ero.|
