The wasps (Chrysididae) together with the Platt wasps (Bethylidae), dryinidae (Dryinidae) and the families Sclerogibbidae, Embolemidae, Plumariidae and Scolebythidae the superfamily chrysidoidea within the aculeata (Aculeata). More than 4000 species are known worldwide , in Central Europe the golden wasps are represented by around 120 species.


With their striking, lively shiny metallic ( iridescent ) coloration, the golden wasps are among the more conspicuous representatives of the hymenoptera, even if the European species hardly reach ten millimeters in body size. Many species are even smaller than five millimeters.

The golden wasps differ from other wasps by reducing the number of visible limbs of the abdomen to 5 or fewer. The remaining segments are telescoped into one another and form a laying tube in the females and a genital tube in the males, which are usually drawn into the abdomen and are not visible. The poison sting has withered.

The antenna whip is eleven-limbed, it sits on a pedicellus that is connected to the basal limb (scapus). The labial palps are tripartite, the maxillary palps consist of 5 limbs.

There are no closed cells on the hind wings .

Way of life

All golden wasps have a parasitic way of life, albeit in different forms: there are brood parasites , similar to the cuckoo bees , in which the larva kills the host larva and then feeds on the food supply , and parasitoids that attack the adult larvae or pupae of the host species. Numerous stinging voices from the groups of solitary folded wasps , digger wasps or bees come into question as host species .


The golden wasp family comprises a total of 83 genera. These are grouped into 5 subfamilies, if one adds the subfamily Parnopinae , which used to be known as the tribe Parnopini within the subfamily Chrysidinae . In the Amiseginae , Cleptinae and Loboscelidiinae the males have 5 visible abdominal segments, the females 4. The males of the Parnopinae have 4, the females 3. In the tribe Allocoeliini of the subfamily Chrysidinae, only 2 tergites and 3 sternites are visible in both sexes . The other tribes of this subfamily each have 3 abdominal segments in both sexes.
