Ants are often attacked by blood-sucking parasites such as mites. Some people regard ants as harmful especially those who collect cereal seeds or keep aphids domesticated in the garden.
Furthermore, skin contact with the poison from fire ants can cause allergic reactions. Ove... | | |

Later, they eat the whole insides of the pupae. After that the black slip wasp larvae pupate. 2 weeks later the young black slip wasps hatch and bite through the skin of the butterfly pupae. The adult black slip wasp ov... | | |
| | | Adult Chaoboridae are not blood-sucking insects and prefer the proximity of water. Some species feed on nectar, while others appear not to take food. | | |
| | The mouthparts have degenerated in many species and are not suitable for penetrating the skin, therefore they do not suck blood. Their antennae are hairy and can thus register more vibrations. The wings are usually very well developed and can be shaped differently according to the gender of the insect. In resting position the wings are posited roof-like on the body. Chiro... | | |
| | The bodies of Chironomus atroviridis are medium in size, soft-skinned and delicate. The mouthparts of these insects are not suitable for stinging or sucking blood. Their antennae have discrete groups of hairs on their surface which are capable of improving their ability to detect vibrations. The chest (thorax) is very arched. The wings are well developed and are posited roof-like on the abdomen in resti... | | |
| | Root-maggot flies prefer to live on flowering plants, where they feed on the nectar and pollen. However, they also sometimes feed on liquid manure, sweat, blood or the watery discharge from wounds. Some species live on rotting seaweed, others reside in the nests of bees or wasps, where they eat the food reserves of their hosts or the unwanted remains of these. | | |
| | Anthomyia pluvialis are active from May to October. The males are often encountered in groups in the shade of trees. The adult flies feed on nectar and pollen from flowering plants, the females suck the blood of other insects or conspecifics. | | |
| | Many species have a metallic sheen or are brightly coloured.The antennae have 3 to 7 segments (depending on the species) and widen at the top. By increasing blood pressure, these fins will increase even too. Some species have very broad, externally serrated forelegs, which help them when digging in the ground. | | |
| | Lepidopterans usually only ingest liquid food (nectar, water). A few species live off animal excrement, urine, sweat, blood or even tears. Caterpillars often eat their own egg shells after hatching, and then feed on leaves, pine needles, flowers, seeds or fruits. Some caterpillars live as social parasites with ants. | | |
| | ...e Bombycidae and the caterpillars of the silkmoth (silkworms) are of importance. These caterpillars are considered pests especially in gardens and monoculture farming, because an infestation leads to significant crop losses. Lepidopterans which suck blood or tears are considered to be disease vectors. | | |
