Spider-hunting Wasps

Spider-hunting Wasps, also called Spider Wasps and Pompilid Wasps, as their name indicates, prey on spiders of all sizes. The spider is paralyzed by the sting and an egg laid on or beside it. Where size allows, the paralyzed spider may be dragged to a nest hole. The hatched larva eats the spider. There are some 40 species of Spider-hunting Wasp in the UK.
