| Fertilized females lay their eggs in flight, on sedentary or slow-flying hosts (bees, bumble bees or wasps). The larvae hatch and burrow into the abdomen of their host animals and feed on their insides until they are completely empty. They pupate and overwinter in the... | | |

| At present in Europe, the majority of scoliid wasp species are black and yellow. Male specimens of the subfamily Proscoliinae are almost uniformly black in colour, while females are predominantly of a reddish hue. Scoliidae are more or less hairy. The antennae of the males are straight and divided into 13 segments, while the shorter antennae of the female are heart-shaped or spiral and consist of 12 segments. The mouth par... | | |

| Males and females of most species have colourful or dark wings. Only a few species (also differong by gender) have no wings. The fine, longitudinal veins in the tips of the fore wings and hind wings are an identifying characteristic. The markings on the wings may be ... | | |
|
| After mating, the fertilized females lay hundreds of large, light coloured eggs on meat, often on living or dead earthworms. For this reason they also penetrate rooms where meat is stored for human or animal consumption or processing. Egg laying also takes place on open wounds. Meat th... | | |

| The canary speckled wood is encountered throughout the year, at altitudes of 200 to 2000 metres in wooded areas, forest edges, on cultivated land, in gardens and at grassy cliffs. The females lay their eggs on the food plants (grasses) of the caterpillars, which hatch approximately 10 days later. | | |
|
| After mating, the fertilized females lay their eggs separately in each brood cell in the nests of mason bees (Osmia), Anthophora, potter wasps (Eumenidae), pill wasps (Eumenes), Vespidae or sphecoid wasps (Spheciformes). The host insects try to prevent the rubytail wasps from entering ... | | |
|
| The females lay their eggs in almost any appropriate water, regardless of the volume. The larvae of the mosquitoes develop under water. They get oxygen from the water surface, through a proboscis, which is located at the back end of the body. They feed on micro... | | |
|
| The females lay their eggs in ‘packages’ in wet or muddy ground. The eggs overwinter there. In spring the eggs are transported into water by the rain. The pre-larvae soon hatch from their eggs and fully develop into larvae. At the end of June, after one year of... | | |

| .... 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. From mid-August to September, the females migrate back to the roses to store their eggs in the bark, which then overwinter. | | |
|
| After mating, the fertilized females lay their eggs in plant tissue. The larvae of Eupteryx aurata develop into adult cicada in 5 stages. The body structure of the larvae is roughly equivalent to that of the adults. In Central Europe, the 2nd generation each year overwinter as eggs. | | |
