Beewolf
Beewolves (genus Philanthus), also known as bee-hunters or bee-killer wasps, are solitary, predatory wasps, most of which prey on bees, hence their common name. The adult females dig tunnels in the ground for nesting, while the territorial males mark twigs and other objects with pheromones to claim the territory from competing males.
Batozonellus lacerticida
This species hunts large orb weaver spiders (Araneidae family), mainly "Argiope bruennichii", "Argiope lobata", "Araneus angulatus" and "Araneus ventricosus". The wasps paralyze these spiders with their poisonous stings and drag them into their underground nests. Then they lay an egg into the abdomen of their prey.
