Methochinae

Medium-sized, black solitary wasps with the female having a red thorax, propodeum and part of the antenna. Female wingless. The larvae are parasitoids on larvae of tiger beetles (Cicindela). The female runs over the surface of the ground looking for the burrow of its host. When found, the wasp allows the host's larva to grasp her around her heavily armoured thorax. As the host comes out of its burrow the wasp bends its gaster down and stings the larva below the head capsule. The larva is quickly immobilised and the wasp then pulls it deep into the burrow where she lays a single egg on the ventral side, usually behind the coxae of the hind legs. The wasp fills the burrow with grains of sand, small twigs and small fibrous pieces of humus before leaving. Probably one generation a year. Nationally: 1 species.
