features
The wasps have a body length of 5–8 millimeters. The head and mesosoma are mainly greenish-blue. The mesoscutum and the front edge of the pronotum are red or gold-red in the female, while in the male they are gold-red to greenish in color. The mesoscutum is usually darker in the middle of the males. The metasoma is mainly red in the female, and gold-green in the male with a greenish, bluish or black apical border. The tergite T2 often has a black dorsal spot in the female. The wings are transparent.
distribution

In Europe, their distribution area extends from Sweden and Finland through Central Europe (France to the Baltic States and Hungary) to Spain and Italy in the south. With the exception of Jersey , the species is not represented on the British Isles . In North Africa, Chrysis bicolor occurs in Morocco . In the east, the distribution area extends to the Far East of Russia .
Way of life
Chrysis bicolor parasitizes endogeic (in mineral soils) nesting digger wasps of the genera Dinetus and Tachysphex . The following host species are mentioned: Dinetus pictus as well as Tachysphex obscuripennis and Tachysphex pompiliformis .
The golden wasps can be seen from June to the end of August. They prefer open sand biotopes and dry grasslands as habitats.
Similar species
Chrysis illigeri - is similar in color and difficult to distinguish. The distance between the lower eye orbit and the mouth is equal to the basal width of the mandibles , while in Chrysis bicolor this is a maximum of 3/4 of that. Furthermore, the stippling of the second tergite is less pronounced than in Chrysis bicolor . In addition, the metascutellum is more elevatedin profile in Chrysis bicolor .
