Hedychrum rutilans is a species of cuckoo wasps (insects in the family Chrysididae).

The species occurs primarily in Austria, Italy, Bulgaria, Greece, France, Poland, Portugal, Spain, Switzerland and in North Africa.

The color is more green and partially golden in the male and more extensively golden-red in the female.

The female cuckoo wasp lays its eggs on the paralyzed honeybee workers serving as provisions for the beewolf larvae, placed by the female beewolf in its brood cells.

[4] Adults grow up to 4–10 mm (0.16–0.39 in) long and can be encountered from late June to September, often feeding on flowers of Mentha species, Achillea millefolium and Euphorbia paralias, but also on honeydew or various exudates.
