This structure, in addition to the structure of the antennae and the body shape, is an essential feature in the identification of the various species and gave rise to their common name in both English and German. Here, the number of strips and the mesh of the lattice plays an essential role. The wing membranes are difficult to discern beneath the ‘lace’. There are species with well developed wings and others which cannot fly because their wings are too short. The lace bugs a... | | |
| | Lace bugs feed solely on plants, either on individual plant species (monophagous) or on a limited number of plant families (oligophagous). This is reflected in the name of each species (hawthorn lace bug, sugarcane lace bug, avocado lace bug, azalea lace bug etc. ). Lace bugs sit on the flowers and leaf undersides of their host plants. These insects ar... | | |

Adult scarabs reach body lengths ranging from 5-60 mm. These almost strongly-built beetles due to a big number of external characteristics allow a distinction by gender. In the case of the European rhinoceros beetle, the males have a distinctive "horn" on their foreheads. | | |
| | 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. | | |

The hinder area of the wings has the same markings. The hind wings have 2 short tails (spores) and a number of blue spots on the upper surface. The underside of both pairs of wings has a vibrant patchwork of stripes and spots. | | |
| | The females lay the first generation of eggs in spring in loose, moist soil or in damp meadows, in gardens or in cultivated land. The eggs are oval and about 1 mm in size and can number up to 1, 200. The larvae hatch after 15 days and feed on fallen leaves or on the roots of young plants. They can cause considerable damage in horticulture and agriculture. 300 to 400 larvae per square metre of usable area is not uncommon. The larvae... | | |

The short period of development and large number of offspring leads to a high density in the small fruit fly population, and this causes substantial losses to growing fruit as well as fruit in storage. On the other hand, the small fruit fly is of major importance in genetic research. | | |
