| ...he longest period of their lives and can last 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 enemies like birds, hedgeho... | | |
| | Yellow swarming flies are encountered mainly in grasslands. When they are on the hunt for habitats to overwinter, they sometimes appear in swarms of millions (mostly females) in residencial and other buildings. Each year they return to the same buildings. The reasons for this are uncertain. The adult flies overwinter without food. | | |
| | Some species of lace bugs overwinter as adults. After mating, the fertilized females use their ovipositor to lay their eggs almost exclusively on the underside of the leaves of the food plants of their larvae (nymphs). The eggs of some species spend the winter there. The hatched larvae...
...ages, in some species, just 4. The metamorphosis of the larvae of lace bugs is incomplete because it does not involve a pupal stage. The transition from nymph to adult lace bug is finished with the last moult. The nymphs of some species of lace bugs overwinter on the food plants. | | |
| | The larvae hatch after 1 to 3 weeks. They are 2 – 4 mm in length and eat tunnels to the soft cambium (layer between the bark and sapwood). Here, they take in nutrients (vitamins, minerals) with the tree sap. Once they reach the cambium layer, they overwinter. The following year, before eating, they penetrate into the harder sapwood. Here they overwinter for the second time. | | |
| | ... even the food supplies of their hosts (only insects, no pollen) have been consumed, and they spin a cocoon for themselves in the host’s 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. | | |
| Adult rose leafhoppers fly away when disturbed, while the nymphs make long jumps to escape. Rose leafhoppers reproduce twice a year., They can breed especially well in warm summer weather. The eggs of the second generation overwinter in the bark of the sprouts of roses. The larvae, hatch in the spring and possess only rudimentary wings. The adult cicadas (fully developed and equipped with wings) move to their summer host plants in June, as well as to plants of the genus Capsicum...
...t cicadas (fully developed and equipped with wings) move to their summer host plants in June, as well as to plants of the genus Capsicum. From mid-August to September, the females migrate back to the roses to store their eggs in the bark, which then overwinter. | | |
| The caterpillars of the last generation overwinter. They pupate in spring of the following year and emerge as adult butterflies in May. The adult brown argus butterflies are active from May to June. During this time they mate and reproduce. The fertilized females always lay their eggs on the host pl...
...ent. They are greenish and have a pale line lengthwise on each side. When they have reached a length of about 20 mm they pupate. They hatch from the pupae from late July to mid September and produce the second annual generation of caterpillars which overwinter in leaves in frost free places. | | |
| | Forest bug feed by sucking out the insides of fruit. They occasionally kill other insects and suck dead other arthropods (insects, arachnids, crustaceans etc). After mating, the females lay their eggs on top of a leaf. The larvae overwinter - unlike those of other kinds of shield bugs - under the bark of trees, and their further development takes place on broad-leaved trees. | | |
| | The green shield bug does not overwinter in the larva state. Mating and egg-laying take place in early summer. A female lays up to 100 eggs. The larvae hatch and go through 5 phases of development, becoming adults in September. During these phases of development the larvae remain together.... | | |
| | Queens overwinter. They appear in March or April. Bombus pascuorum nest both above ground (old birds’ nests) and below ground (abandoned mice nests). The bees use moss, grass and animal hairs to construct a hollow sphere inside the nest. The interior of the hollow sp... | | |
