...each body lengths of 4-9 mm. Their bodies are oval-shaped, with a very flat underside. They have a slightly metallic sheen, are deep black in colour and shimmer slightly bronze when seen in light.
Adults have short, club-shaped antennae. Their mouthparts (maxillary palpi) are elongated, yellowish to reddish-brown in colour and hair-like (filiform) and may be mistaken for antennae. The maxillary palpi like the antennae often have dark ends. On the wing covers (elytra) are 10 stripes of fine, pu...
... lengths of 3-4 mm) hatch. They increase rapidly in size . The larvae feed (starting at the lastest three days after hatching) ) on smaller aquatic animals, and are even prone to cannibalism. In water they catch floating prey with their clamp-like mouthparts (mandibles), hold them tight and swim with the living prey intact to the water’s edge. Having found a good landing point, they put their abdomen on the solid ground and move themselves backwards with tracking the prey over the shore. They crush the... | | |
| | Notably, the females’ clypei (the broad plate at the front of an insect's head) have smaller or larger bulges, which have a simple conical shape, or may even look like little horns. The mouthparts (mandibles) of the females are elongated and have a tooth-like appendage, to capture prey and facilitate their transport to the nest. Different species of the genus Cerceris can be recognised by the shape of their mouthparts. The abdominal segments are strongly constricted at the nodes so that the abdomen appears to have a strongly undulating surface. | | |
| | | The antennae are an identifying characteristic for assignment to a particular family and they can be filiform, serrated or feathered. Their mouthparts are highly specialized. The length of the proboscis varies dramatically and may be up to 280 mm in subtropical species, and completely regressed in others. The lepidopterans are capable of registering sound. | | |
| | ...The head and chest form one unit (Prosoma). This is followed by the abdomen which is usually significantly bigger. Araneae are Chelicerata. At the end of the head are retractable claws, containing glands which secrete poison. They do not use theit mouthparts (at the male as genitals) for chewing their food. Four pairs of legs are attached to the prosoma and each leg comprises six to seven segments, which in addition to the hairs on their legs build an important sensor system. | | |
| | Fossil findings of Nematocera date back to 170 million years ago. The family includes 35 genera with 2,700 species. 104 species occure in Europe.
Nematocera are delicately constructed, with slim, wire like antennae and long thin legs. Their mouthparts are usually used to sting and to suck up food.
The Nematocera are found throughout the world, mostly in the vicinity of water. Different species are common in different areas. They feed on blood, which they suck from mammals, birds, reptiles or ... | | |

The antennae are different lengths in different species. Crane flies can only ingest liquids with their mouthparts. They are not able to sting. | | |

There are several simple eyes (ocelli) on the top of the head. The mouthparts are designed for licking up juices. The antennae are tripartite and almost completely hairless, while those of Melanostoma scalare have short hairs. | | |
| | The bodies of Valenzuela flavidus are yellowish to light grey in colour. They have long, thin antennae with 13 segments. Their mouthparts consist of an intermediate form of chewing and sucking tools. The bright, upper surface of the thorax bears a brown patch at the front and laterally. The wings are dark and their veins stand out clearly. Dark coloured spots can be seen on the upp... | | |
| | They all possess stinging-sucking mouthparts (a sting, a proboscis). Their antennae are relatively long and have one or more segments. The proboscis (rostrum) starts below the back of the head (in the hip region of the first pair of legs) and hangs backwards on the underside of the chest (thor... | | |
| | ...ize. They are a member of the subphylum Chelicerata having the chelicerae – the appendages which appear before the mouth - which give the group its name. On the end of the Chelicerata are retractable claws, and in their points are poison glands. The mouthparts (which also are part of the genitals on the male) are to find on the head too. Attached to the prosoma are 4 (six to seven jointed) leg pairs, which (together with the sensitive hairs) build an important sense organ. On the abdomen of the female spi... | | |
