| Earwigs prefer warm habitats. They feed on plant parts and waste, or live off small insects. They are most active at dusk or at night. During the day they hide under bark or stones. | | |
|
| Moths and Butterflies are of great importance as bio-indicators and plant pollinators. Caterpillars, butterflies and moths have a large number of enemies. Many lepidopteran species are endangered, although this is mainly due to the increased use of pesticides in agriculture. | | |

|
| Egg-laying (up to several hundred eggs in a lifetime) is done with an ovipositor in moist soil orin the mud at the bottom of a body of water. The larvae reach body lengths of about 50 mm and live on plant roots, which they eat. They pupate in the soil or in rotten wood. Crane fly larvae can cause significant damage to crops. | | |
|
| Scentless plant bugs mainly feed on soft materials - leaves, flowers, young stems - and herbaceous plants and can cause considerable damage to crops when they occur en masse. | | |
|
| Their preferred food plants are: St. John's wort (Hypericum perforatum), Geranium robertianum and Clinopodium vulgare in addition to various other herbaceous plants. They feed on plant juices or juice from seeds and fruits. | | |
|
| Mayflies always live near water. Their life expectancy ranges from a few minutes to a few days. The females lay their eggs on standing or flowing fresh water. The newly hatched larvae breathe through tracheal gills. They feed on algae, plant parts and tiny crabs. Larval development usually takes 1 year, but can take up to 3 years depending on the species. During this period the larvae shed their? skin - up to 30 times. In the final stage of development the sub-imagos (pre-adults) h... | | |

Some species of the subfamilies Mesostoinae and Doryctinae are therefore well known for depositing their eggs in plant leaves (they lay their eggs in bile). | | |
|
| The life span of the adults is often only a few days. The larvae live within almost all parts of plants. Some species inject their eggs into plant leaves on which a small ball grows with the eggs inside, other species live parasitically in the implantations of other insects. | | |
|
| After mating, the fertilized females lay their eggs at the base of grasses (Poaceae). After hatching, the maggots eat their way into and through the young sprouts and later feed on the young leaves of the grass plants. Further growth of such plants can be disrupted by this, or even prevented. The damage patterns on grass plants vary. Ragged, cracked leaves, are often seen, as are swollen stems at ground level or near the ground, or the formation of 3 to 4 stalks on the same plant. Seedlings may be cut off at the base. The maggots reach body lengths of up to 5 mm. Approximately 30 days after hatching from the eggs, the maggots have completed their development and they leave the host plants and pupate. | | |
