Adult Vespinae mainly feed on small parts of dead or living animals, from insects, pollen, plant juices and from nectars. Their larvae are mainly fed on animal meat.

| | 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 live in sand or salt, or in or on water. In rare... | | |
| | | As is typical of insects , bugs’ bodies comprise three sections. In general, they have a broad and oblate shape (flattened at the end). At the front, they have a sucker and 2 antennae. Heteroptera are mostly plant suckers. Ectoparasites such as the bedbug suck blood.

Like all bees, the honey bee has mouth parts, which can lap up sweet plant secretions (nectar and honeydew). Nectar is transported in part of the stomach called the "honey stomach". Other bees on the same level in the hive are supplied with nectar by this bee.

| | Ladybirds eat aphids, scale insects, powdery mildew, fungi, Spider mites, true bugs, thrips, beetle larvae, or larvae of Tenthredinidae and larvae of Lepidoptera. When food is short ladybirds also feed on plant substances. Cannibalism can be encountered among both adult ladybirds and their larvae. | | |

The hatched larvae, which are resist to the cold, are usually hairy and are found en masse (especially in the upper layers of humus). They live on rotting plant remains and are important soil regenerators. The pupae of Bibionidae also live in the soil. The larvae can be harmful when they occur en masse especially in times of drought as they also attack the roots of living plants. | | |
| Moth flies usually feed on plant juices or nectar, however some species do not eat at all. The females of the genus Sycorax sting frogs and suck their blood. The tropical Sand flies are known to tranmsit diseases. As moth flies are not good flyers , their move often is complet...
...e are slender and have a body length of up to 4 mm. They have a very distinctive head shape. The larvae of Moth flies live in a variety of habitats such as water, forest soil, moss, fungi or in heavily polluted water (i.e. drains, sewage treatment plants).

The main food source of the Bibio marci are different plant juices, nectar and sometimes pollen. Bibio marci like living in bushes, shrubs or on small plants. | | |
| | Pollen | Pollen is a floury substance, produced by seed plants. It consists of single grains (microspores) with a resistant wall (sporoderm). The sporoderm has an inner (intine) and an outer (exine) structure.
The cell is completely surrounded by the intine. The outer layer of the intine has a high pectin ...
... intine develops into a pollen tube.
The exine has two-layers and consists mainly of sporopollenin. The structure is determined by the pollen grain. Pollen grains vary in size, shape and surface structure, so that it is possible to identify what plant genus and species they come from. Pollen grains reach average sizes of between 10 and 100 microns. They have one or more apertures, which lack the outer layer of the exine so that the intine can grow through into a pollen tube.
Pollen grains ar... | | |

There are two kinds of honey : blossom honey (from the nectar of flowers ) and honeydew honey (from the excreta of plant sucking insects, and from plants’ secretions.
The following are examples of blossom honey: rape honey, acacia honey, dandelion honey, sunflower honey, heather honey, clover honey, chestnut honey and linden honey. Some examples of honeydew honey are: forest honey, pine honey a... | | |
