| Female maps of the first generation (spring) reach wingspans of up to 38 mm, those of the second generation (summer) reach 43 mm, while the males can reach spans of 32 mm in spring and 38 mm in summer. The body of the butterfly is slim and the upper surface is a black-brown colour. The underside is lighter and slightly hairy. The rings on the segments are white. The upper surface of the wings in the spring generation is a brownish-red to orange colour and is interspersed with black patches. The summer generation are black-brown to black or sometimes blue-black) The undersides of the wings in the two generations differ only slightly. | | |
| The Pear Sawfly prefers habitats such as forests and gardens. Depending on the weather, it produces 2 or 3 new generations a year. Reproduction is normally parthenogenetic (without males). The females of the spring generation leave the soil in early May and lay their eggs, in June, on the leaves of different plants, such as cherry, pear, juneberry, mountain ash, hawthorn, quince, birch or roses. They scratch into the leaf tissue with their ovipositor, forming ...
...n July and August), the adults of the 2nd cherry slug generation hatch, mate and lay eggs. The larvae (cherry slugs) are active from September to October. They also pupate and overwinter in the soil. They leave the pupae as adult cherry slugs in the spring. | | |
| | | In spring and autumn, the females dig tunnels into the ground, where they lay 50 - 90 eggs. The eggs, as well as the hatching larvae of the spring generation, are guarded by the females. The larvae shed their skin 4 - 5 times. They are similar to the adult earwigs, but are much brighter lighter in colour and without wings. They reach maturity in approximately one month. | | |
| | ...st several years, with the living of the larvae is often similar to the living of the adult beetles. The living of the larvae affects the duration of their larval stage.
In the Palearctic beetles mostly overwinter as pupa and slip off during the spring. Some species overwinter as adult beetles (for example: ladybirds and Hydrophilidae).
The most important natural enemies of the beetles are pathogens (viruses, bacteria, protozoa, fungi), parasites (Ichneumon wasps, tachina flies, Acarina) and en... | | |
| | Females are 20 to 28 mm in length. They overwinter in caves beneath the ground or in leaves. They lay their eggs in the spring, in mouse or mole holes, and even in walls or under rocks. The containments for pollen, honey and for the brood are built from wax. When the labor force hatches the nest expands to accommodate up to 500 bumblebees. Nests in soil can have a depth of... | | |

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.
Wasps have a smooth sting which they use to inject crippling substances into their prey and to defend themselves (even by spraying poison) and this sting can be used again and again. The H... | | |

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 ... | | |
| | Maps prefer to live in damp areas with nettles, which blooms - in addition to those of the Velcro – are delivering food (nectar). In Germany, the map overwinters as a pupa. In April, the spring generation hatch, the males slightly earlier than the females. | | |
| | The common wasp nests both above and underground nest construction begins in spring. Often they exploit existing cavities which were previously used by other animals which they then expand considerably. Dark cavities in buildings are also often used for nesting. | | |
| | ... to seek out human settlements. The females spin webs almost the whole year round. 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. | | |
