| Scoliid wasps | | The scoliid wasps (Scoliidae) are a small family in the order Hymenoptera - unranked: wasps, ants and bees (Apocrita) – in the suborder Aculeata and the superfamily Vespoidea. The family Scoliidae is divided into 2 subfamilies, the Campsomerinae (synonym: Proscoliinae) and the Scoliinae. Both subfamilies together comprise about 300 species. 20 species from 6 different genera are known in North America. | | |
| | The scoliid wasp larvae hatch after about 1 week, under favourable conditions. For 1 - 2 weeks they feed on the body fluids of the host larvae and from the 4th larval stage on they eat the rest of the host larvae. After their last larval stage, scoliid wasps pupate in cocoons, which are often reddish to brown in colour. The Scoliidae larvae of most Palearctic species overwinter in a preliminary pupae stage. About one month after hatching from the eggs, the adult Scoliidae of the new generation hatch from their cocoons.
Scoliidae are occasionally used by humans to combat grubs. | | |
| | | 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... | | |
| 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 animal...
...y 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) are flower visitors, feeding on nectar or honeydew. They are not aggressive. | | |
