They are highly organized and have a social stratification system (caste system), with each insect performing a particular task. Several million ants can live in a colony. Most of these are infertile females and are workers or soldiers with duties both outside and inside the nest.
Only the queen ant can produce eggs. The males - like the y... | | |

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....
...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 spider wraps the prey in silk and offers it as a "bridal gift" to the female. While the female spider eats the gift , the successful male starts a courtship ri...
...e 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. | | |

Half blankets and neck shield have a dark brown to black hue and the centre and tips of the wings bear patches of yellowy - red. On the upper side of the insect is a yellow mark in the shape of a small heart. These bugs have large complex eyes. The head and legs are lighter in colour than the rest of the body.

The wings are usually very well developed and can be shaped differently according to the gender of the insect. In resting position the wings are posited roof-like on the body. Chironomids have a life expectancy of a few days. | | |
| | ...similar dripped designs, The females have a poisonous sting at the end of their abdomens; the drones lack this sting but have, in its place, sex organs. The wings of the european hornet are reddish-orange in colour. A characteristic feature of this insect (apart from the body size) is the deep humming tone produced when flying. | | |
| | After mating, the fertilized females lay their eggs inside or even on the surface of larger adult stink bugs. The female achieves this by holding the host insect in a complicated clamp apparatus. The females have no ovipositors. | | |

The host larva are thus stowed in an "incubator". One egg is placed on each host insect. During a period of one to three months, Scoliidae females can lay 50 or more eggs. After egg laying the female leaves the tunnel. | | |
