| | ...the Scoliidae to bury themselves in the ground. The burial, if it is not for the night only, especially in the female specimens allows access to the soil or rotting wood, where different species of scarab larvae live, which are amongst the preferred host animals of the Scoliid wasp’s larvae.
Scoliidae prefer warm temperatures. Adults (especially Campsomerinae) are flower visitors, feeding on nectar or honeydew. They are not aggressive. | | |
| | | At the end of the larval period the caterpillars pupate on their host plants, where they prefer sheltered places such as niches. The pupae hang down from grass fronds near the soil. The pupae are difficult to make out on dry soil and leaf litter because of their camouflage colouration - yellowish green, later brownish... | | |
| | From April on, the larvae hatch. First they suck juice from the fresh leaves and the shoots of their host plants. The larvae (nymphs) are light green to deep green in colour and have orange-spotted antennae. In the 2nd to 4th larval stage, they swop over to herbaceous plants (potatoes, beets, strawberries, etc. ). | | |
| | Mosquitos can host pathogens (viruses, bacteria or parasites) and therefore represent a danger to humans. While their bites can cause pain, in addition to allergic reactions, the hosted bacteria can transmit various fever diseases depending on the region, such as yellow fever, dengue fever or malaria. In some places the fight against mosquitoes involves spraying BTI bacteria over large areas. This method targets the larvae.

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. | | |
| | ...dult Anthaxia podolica settle on flowering plants. where they specialized are limited to certain plant species. They are oligophagous. Sometimes they only settle on yellow flowers. They feed on flower petals, or on the herbaceous components of their host plants. | | |
| | It feeds on nectar from thistles and cornflowers. In May or June the females lay about 100 to 300 eggs in groups on the host plants, on the undersides of the leaves. The caterpillars hatch after about 2 weeks and are yellowish-green and spotted black. They eat in groups. The older larvae are solitary. The caterpillars can be encountered from June to October and reach leng... | | |

In April of the next year, the hairy caterpillars hatch from the eggs and start to feed on their host plant. They are sociable at first and later solitary. | | |
