The name Chrysis ignita is often confused with several other species in the same genus. Recent studies based on DNA-barcoding reaveal that C. ignita is a rare species. For instance from Norway, there is only one known locality. Probably the species has declined all over the region. Hosts probably include Ancistrocerus parietum. The species is similar to C. terminata but the frontal carina is not forming tooth-like tubercles.
