...y. In case of danger or disturbance, the spider falls back into the vegetation and adopts a special posture as camouflage. At to the soil the autumn spider can often be found in the company of spiders from the family Linyphiidae.
Males survive mating, which occurs in September and lasts only a few minutes Before mating takes place a number of sexually mature males appear in the vicinity of the orb-web of the female , where they wait for the female’s readiness to mate. If an insect gets caught in the female’s web, the males race towards it and the fastest spide...
...male. While the female spider eats the gift , the successful male starts a courtship ritual during which it drums and plucks at the threads of the web to get the full attention of the female. When the female is ready, she takes position on a mating string at the rear of the web. After mating the male spider leaves.
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 s... | | |
| They also feed on dung heaps and carcasses to obtain protein and minerals. 30 000 to 50 000 flies can be encountered at the same time, especially in autumn when they gather to overwinter and to mark their mating spots with special scents in the vicinity of their winter habitats for next year. In extreme cases, several hundred thousand can gather. In spring, after overwintering, the flies meet up at the marked places. Male Sepsis fulgens usually then vis...
... of their winter habitats for next year. In extreme cases, several hundred thousand can gather. In spring, after overwintering, the flies meet up at the marked places. Male Sepsis fulgens usually then visit dung-heaps where they await females for mating. The mating takes place at another location later on.
The female flies lay their eggs on dung-heaps or compost heaps. From the first or second day after hatching, the larvae begin feeding on feces or rotting parts of plants. At the end of their third la... | | |
| | | The fertilized females lay 20 - 30 oblong eggs, about 0. 5 mm in length, immediately after mating. This is done near the water’s edge, in the presence of the males who keep watch. After oviposition the females are guided back to the riparian vegetation by the males, and mating occurs again. The grip of the female on the male is so strong during mating that the blue wax layer at the end of the male’s abdomen dissolves and the tip turns black. | | |
| | During the mating season, (which is from mid July toAugust), the males can be observed on "patrol" flights, looking for females. During these, they often stay in the air. They fight with rival conspecifics when entering their territory. Mating almost always begins near the ground and often ends at the top of trees or bushes near water. | | |
| | Mating, which is not initiated through courtship by the males, takes place in May/June. Through the use of a special grip, the male spiders avoid the female’s 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 you... | | |
| | Scarlet dragonflies prey on insects (flies, mosquitoes), or on spiders, which they catch while in flight. They have their own territory which they defend against rivals. The mating season of the scarlet dragonfly is from May to August in Central Europe, and from April to October in the Mediterranean. Mating begins within a few seconds of flight and is usually continued on the ground. | | |

They hunt in the evening and can only be observed flying in daylight during the mating season. Mating starts in the air and is completed after 5 - 10 minutes on a solid surface, on the ground or on plant parts. | | |
| In late March, the adult bees of the first generation hatch. The males appear first and fly back and forth over the soil nests on hot days. Mating takes place in April. Immediately afterwards, the fertilized females begin constructing the brood nest in the ground. Nest colonies form/can form, comprising several hundred - up to one thousand - individual nests in a relatively small area. The nes...
...the larvae by the females, a single egg is deposited on the food and the brood chambers are closed. Shortly after hatching, the larvae of the 2nd generation start feeding on the food supply. They develop in their chamber. Approximately 3 weeks after mating the males die. The females care for their brood until the end of May and then they die too. The larvae are left to fend for themselves until June when they pupate. In early July, the adults of the 2nd generation hatch from their pupae. They are acti... | | |

...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... | | |
