The European beewolf (Philanthus triangulum), also known as the bee-killer wasp or the bee-eating philanthus (from the now obsolete synonym Philanthus apivorus), is a solitary wasp that lives in the Western Palearctic and Afrotropics. Although the adults of the species are herbivores (feeding on nectar and pollen), the species derives its name from the behaviour of the inseminated females, who hunt western honey bees. The female places several of its paralysed prey together with an egg in a small underground chamber, to serve as food for the wasp larvae. All members of the genus Philanthus hunt various species of bees, but P. triangulum is apparently the only one that specialises in western honey bees.
The European beewolf is a species of solitary wasp with bold yellow and black markings on the abdomen, males have trident-shaped markings between their bluish eyes while the larger females have a reddish stripe behind the eyes and a pale face.
The European beewolf is found mainly in areas of open sandy ground in areas such as lowland heathland and coastal dunes. They are infrequently found in clay areas and in Britain have been recorded digging burrows... Wikipedia →
