Die Gemeine Goldwespe oder Feuer-Goldwespe (Chrysis ignita) ist eine Art aus der Familie der Goldwespen (Chrysididae).
Die Gemeine Goldwespe ist eine Art von parasitischen Insekten, die in Europa und Westasien vorkommt. Sie hat eine variable Körperlänge von 4 bis 13 mm und einen schlanken Körper mit leuchtend grünblauem Kopf und Thorax. Ihr Abdomen ist kupferrot bis rot metallisch-glänzend, wobei die Unterseite grün oder blau metallisch ist. Sie befällt eine Vielzahl von Stechimmen und legt ihre Eier in deren Nester, wo die Larven die Eier und die Nahrungsvorräte der Wirte fressen. Die Gemeine Goldwespe ist die häufigste Art von Goldwespen in Mitteleuropa und fliegt von April bis September.
Chrysis ignita is a species of cuckoo wasp. It is one of a group of species which are difficult to separate and which may be referred to as ruby-tailed wasps. Cuckoo wasps are parasitoids and kleptoparasites, laying their eggs in the nests of other species where their young consume the larvae of their hosts. They have a number of adaptations which have evolved to equip them for their life cycle. They have metallic, armored bodies, and can roll up into balls to protect themselves from harm when infiltrating the nests of their hosts. Unlike most other aculeates, however, cuckoo wasps cannot sting. The hosts of Chrysis ignita are believed to be potter wasps such as Ancistrocerus parietum. Chrysis ignita is found across the Palearctic excluding Africa, from western Europe to China and Japan.
Chrysis ignita is a chrysidid wasp with a colorful, metallic exoskeleton and a reduced stinger used as an ovipositor. It can be identified by its distinctive ruby-colored abdomen and textured exoskeleton. These wasps are found in various habitats including walls, cliffs, and areas with dead wood. They are believed to parasitize potter wasp species, but many of the host records are considered doubtful due to misidentifications. Field studies can be conducted using traps or by breeding host wasps in the hopes of observing parasitization. Some specialized Chrysis species have evolved chemical mimicry to infiltrate the nests of their hosts, matching the scent profile of the host wasp to remain undetected.
