| | Female Excentricus planicornis reach body lengths of 4.9 - 5.5 mm and are therefore slightly larger than the males, which are 4.6 - 5.3 mm in length. The body is slenderly built and tapers into a point at the end of the abdomen. | | |

The forehead is yellow at the sides and bears a transparent cyst (the identifying characteristic for all Conopidae). The underside of the female’s face, has a whitish-yellow shimmer with a dark keel. Their compound eyes are large and striking and allow them to see well. The antennae are black with a brown 3rd segment, fan-shaped and stand on humplike black projections which have yellow edges... | | |
| | At present in Europe, the majority of scoliid wasp species are black and yellow. Male specimens of the subfamily Proscoliinae are almost uniformly black in colour, while females are predominantly of a reddish hue. Scoliidae are more or less hairy. The antennae of the males are straight and divided into 13 segments, while the shorter antennae of the female are heart-shaped or spiral and consist of 12 segments. The mouth parts include an extended proboscis even at the lower calyx which allows easier access to the nectar. Between the first and second segment (sternite) of the abdomen is a deep constric... | | |
| | The first pair of legs are strongly built and ciliated. They help the Scoliidae to bury themselves in the ground. The burial, if it is not for the night only, especially in the female specimens allows access to the soil or rotting wood, where different species of scarab larvae live, which are amongst the preferred host animals of the Scoliid wasp’s larvae.
Scoliidae prefer warm temperatures. Adults (especially Campsomerinae) ar... | | |
| After mating, the females lay their eggs, 2-4 mm in length (depending on the species, inside scarab or weevil larvae. The host larva is stung in the neck or chest area and is repeatedly kneaded with the mouth parts (mandibles). The females then build tunnels in the earth, sometimes to a depth of one metre beneath the surface of the soil, and drag the permanently paralyzed host larvae into these, depositing them at the end. The host larva are thus stowed in an "incubator". O...
...of the soil, and drag the permanently paralyzed host larvae into these, depositing them at the end. The host larva are thus stowed in an "incubator". One egg is placed on each host insect. During a period of one to three months, Scoliidae females can lay 50 or more eggs. After egg laying the female leaves the tunnel. | | |
| | The female digs a course in the soil for her eggs. At the end of the tunnel is a chamber which houses the egg and a stunned insect that will later serve as food for the hatched larvae. After oviposition, the nest is sealed and the entrance camouflaged. | | |
| | After mating and fertilization female mosquitoes feed on blood which they suck from mammals, birds, reptiles or amphibians. This is essential for the formation of the eggs, as the blood supplies the protein required for this. All mosquitoes also feed on nectar or fruit juice. | | |
| | The Nigma walckenaeri is the largest species of Dictynidae in Central Europe. While the females reach body lengths of 4. 5 - 5. 0 mm, the males are 3. 5 - 4. 0 mm in length. They have small groups of white hairs all over their bodies. The front section of the female’s body is yellowish brown to yellow, and the male’s is reddish-brown to brown. The male’s head appears posited markedly higher. The central eyes of these spiders are remarkably small. The front section of the chest (sternum) and the mouthparts are b... | | |
