| Heteroptera have a wide variety of forms. With regard to their habitat and way of life they also vary greatly. There are plant sucking species, predatory species and parasites such as the bedbug. Their habitats range from forests and meadows to human dwellings. Some species prefer humid locations such as swamps, while others ... | | |

Royal jelly and propolis are used as raw materials in pharmaceutical products. However, it is also consumed in its pure form and is a legal food substance. Royal jelly can cause allergic reactions in humans even when it has been processed in some way. | | |

They mainly eat the microorganisms which are involved in the decomposition of plant materials. The larvae of other species are omnivorous and eat their way through plant stems or leaves. Others live off fungal cultures or prey on omnivorous insects. Drosophilidae reproduce several times a year. | | |
| | In May or June, the females lay their eggs, often in flower buds. The larvae are roundish in shape and in the initial larval stages live socially with other larvae. They feed in the same way as the adults. By July, the next generation has already reached maturity. In southernCentral Europe, Lygus pratensis reproduce twice a year. The adults overwinter in moss, leaf litter or under tree bark.

| | In late April - early May, it appears on alder leaves once more, in order to start the so-called "maturation feeding". Alder can release hormones, which lower digests the beetle and thus forces it to change host. In this way alder are protected from excessive damage to their leaves. The alder leaf beetle then evades on other alder, willow, poplar, hazel, other fruit trees and herbs. These beetles often occur here in great numbers, which can kill younger trees and ... | | |

Birds pose the biggest threat as they prey on the larvae when they are on their way into the water and especially like to attack the juvenile dragonflies when they have just hatched from the excuvia. | | |
| | Females lay their eggs on sitting or slow flying host animals, especially on bees, bumblebees, wasps, or sometimes grasshoppers. They cling to the host animal and lay eggs between the segments of their abdomen. The hatching larvae then eat their way into the abdomen of the host animal, reside there and feed on the insides of the host until it is hollow. The larvae overwinter in the host insects. Some species, such as Conops flavipes (the most common species of the genus Conops) live in the nest... | | |
| | ...n regions (depending on climatic conditions), they reproduce only once or twice. The adult butterflies of the first new generation appear in July/August, the second generation in September / October. Butterflies of both new generations make their way south in autumn. Many do not make it across the Alpine border and die on the glaciers. In other cases (such as in the British Isles) painted ladies die before their return flight starts. | | |
| | The larvae of the phantom midges live (standing vertically) in water. Their body is transparent (glass rods larvae). They have antennae, which are also shaped in such a way as to function as holding devices for the capture of small insects (eg mosquito larvae) or crustaceans (eg Daphnia). The antennae are used to impale the prey, to crush it and to guide it into the larvae’s mouth. | | |
| | ...dark grey or dark brown in colour, and has a dimpled surface. The diet of the larvae is the same as the adults. If the plant they are on is disturbed while they are feeding, the larvae fall to the ground. Often, they are not able to find their way back to the food plants and run the risk of starvation. | | |
