... opisthosoma is the characteristic leaf-shaped marking (folium) , which varies in colour (often in highly-contrasting red tones). The underside is yellow to brown in colour, with one dark and two bright stripes in the middle.
The legs of the autumn spider are yellow to light brown in colour and have indistinct dark spots and rings. The midfoot (metatarsal) of the first leg pair is (on the ventral side) slightly hairy, ( on the ventral side).
Due to its appearance, the autumn spider can easily can confused with the small autumn spider (Metellina mengei), which is similar in colour. . The species can be told apart by the shape of their genitals, their body size and the hair on the legs of the males.
The autumn spider can be encountered in a wide range of environments, at various altitudes. It prefers semi-open habitats such as forest edges, clearings, box, trees, lawns, gardens, hedgerows, bogs and swamps, where it can be found as a mature adult in h...
...at various altitudes. It prefers semi-open habitats such as forest edges, clearings, box, trees, lawns, gardens, hedgerows, bogs and swamps, where it can be found as a mature adult in herbal layers and shrub layers from August to October.
The autumn spider is diurnal and feeds on insects. It builds a relatively small orb-web which is often close to the ground, The web is not more than about 1.5 metres from the ground. The autumn spider is usually found upside down in the centre of its web or near the edge , waiting for prey. 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...
...tual 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 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. | | |
| | Anomoia purmunda live in forests edges and are common in gardens. They are active from April to autumn. This species reproduces once a year.
The fertilized females of Anomoia purmunda lay their eggs in holes bored into the fruit of hawthorn. The larvae develop in the fruit and feed on it. In autumn they pupate and overwinter in the soil. | | |
| | | Autumn spider | | The autumn spider (Metellina segmentata) in the order Araneae, suborder Araneomorphae (Section: Entelegynae), and the superfamily Araneoidea, used to belong to the family long-jawed orb weaver (Tetragnathidae). It is now in the family Metidae. | | |
| | The autumn spider is found throughout the Palearctic. In Germany and Central Europe, it is the most commonly encountered species of the genus Metellina and is non-endangered. It reproduces once a year. Female autumn spiders are 6.5 to 9 mm in length, males, 5 to 7.5 mm. | | |
| | The mating season of the beetles is from spring to autumn and begins with copulation among the autumn generation of beetles from the previous year, which happens immediately after its release in March / April. Egg laying takes place in several sessions on the food plants of the larvae. The females attach each of the 100 to 600 oval, light to egg... | | |
| | Forest bug | | The forest bug (Pentatoma rufipes) belongs to the family Pentatomidae. It is one of the biggest bugs in Central Europe and can reach a length of 13 to 15 mm. In the summer, it is bronze coloured, in the autumn, dark brown in colour. The upper edges of the pronotum are strongly curved. The neck shield at the top lights in orange. The proboscis is very long. The legs and the first set of antennae are maroon coloured. The larvae of forest bugs are dark. Wit... | | |

While the old queens usually die in the autumn the young fertilized queens seek safe homes. With the cold of coming winter huge numbers of worker wasps die from starvation and as a result many colony wasps become solitary. In spring new colonies emerge from the overwintering young queens.

The colour of the male and female Bibionidae is different, the male being black and the female being reddish brown to amber. In spring and autumn Bibionidae often swarm en masse. They do not sting and they feed on nectar or honeydew. They contribute to the pollination of fruit trees. The insects mate within the swarm, and the males of the Bibio marci for example can become very aggressive.... | | |
| | The common wasp is found in almost every kind of landscape. In areas inhabited by humans, wasps are considered a nuisance in autumn time. The venom of the wasp may cause allergic reactions. When wasps sting hormones are released and this can encourage other wasps to sting. Due to this a large swarm of this kind of wasp poses a great danger to humans. | | |

The adult spider can be encountered from high summer to late autumn. The eggs (laid by the female) survive the winter in a cocoon. The young spiders hatch in the spring. | | |
